Step-by-step explanation:
Simplifying 4 + -2(x + -3) = 24 Reorder the terms: 4 + -2(-3 + x) = 24 4 + (-3 * -2 + x * -2) = 24 4 + (6 + -2x) = 24 Combine like terms: 4 + 6 = 10 10 + -2x = 24 Solving 10 + -2x = 24 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-10' to each side of the equation. 10 + -10 + -2x = 24 + -10 Combine like terms: 10 + -10 = 0 0 + -2x = 24 + -10 -2x = 24 + -10 Combine like terms: 24 + -10 = 14 -2x = 14 Divide each side by '-2'. x = -7 Simplifying x = -7
round off 19340 to 1 s f
Answer:
20000
Step-by-step explanation:
This is because when you round to the signifigant figure, you basically look at any digits at the start of the number, which isn't zero. In this case it would be in the ten thousand 19340. So you round 19340 to the nearest 10 thounsand, which, would be 20000
|6a-5|=4a
the solutions are a= and a=
Answer:
a = 2.5, a = 0.5
Step-by-step explanation:
6a - 5 = 4a, and 6a - 5 = -4a
6a -5 = 4a
Subtract 6a from both sides
-5 = -2a
a = 2.5
6a - 5 = -4a
Subtract 6a from both sides
-5 = -10a
a = 0.5

-Chetan K
Answer:
a=1/2 and a=5/2
Step-by-step explanation:
6a-5=4a:
Subtract 4a from both sides, ending up with 2a-5=0
Add 5 to both sides, ending up with 2a=5
Divide both sides by 2, ending up with a=5/2
6a-5=-4a
Add 4a to both sides ending up with 10a-5=0
Add 5 to both sides ending up with 10a=5
Divide both sides by 10 ending up with a=1/2

2x^2+ 1 = 5x
Answer:
[tex]\frac{5+\sqrt{17}}{4}[/tex], [tex]\frac{5-\sqrt{17}}{4}[/tex]
Step-by-step explanation:
One is asked to find the root of the following equation:
[tex]2x^2+1=5x[/tex]
Manipulate the equation such that it conforms to the standard form of a quadratic equation. The standard quadratic equation in the general format is as follows:
[tex]ax^2+bx+c=0[/tex]
Change the given equation using inverse operations,
[tex]2x^2+1=5x[/tex]
[tex]2x^2-5x+1=0[/tex]
The quadratic formula is a method that can be used to find the roots of a quadratic equation. Graphically speaking, the roots of a quadratic equation are where the graph of the quadratic equation intersects the x-axis. The quadratic formula uses the coefficients of the terms in the quadratic equation to find the values at which the graph of the equation intersects the x-axis. The quadratic formula, in the general format, is as follows:
[tex]\frac{-b(+-)\sqrt{b^2-4ac}}{2a}[/tex]
Please note that the terms used in the general equation of the quadratic formula correspond to the coefficients of the terms in the general format of the quadratic equation. Substitute the coefficients of the terms in the given problem into the quadratic formula,
[tex]\frac{-b(+-)\sqrt{b^2-4ac}}{2a}[/tex]
[tex]\frac{-(-5)(+-)\sqrt{(-5)^2-4(2)(1)}}{2(2)}[/tex]
Simplify,
[tex]\frac{-(-5)(+-)\sqrt{(-5)^2-4(2)(1)}}{2(2)}[/tex]
[tex]\frac{5(+-)\sqrt{25-8}}{4}[/tex]
[tex]\frac{5(+-)\sqrt{17}}{4}[/tex]
Rewrite,
[tex]\frac{5(+-)\sqrt{17}}{4}[/tex]
[tex]\frac{5+\sqrt{17}}{4}[/tex], [tex]\frac{5-\sqrt{17}}{4}[/tex]

1. Un terreno de cultivo en Junín tiene forma de rectángulo de 10m de base y 4m de altura. Debido a que el agricultor desea obtener mayor producción, amplía dicho terreno en dos metros cada lado. ¿En qué porcentaje aumentó el área?
6m + 3z + 4m + 2w - 5z
Step-by-step explanation:
6m + 3z + 4m + 2w - 5z
6m + 4m + 3z - 5z + 2w

The student looks up the word count on his favorite book, if the book has pages that are 5.5 in. x 6.5 in. and 59,540 words how many pages is the book? (This sentence and picture combine.)
Answer:
199 pages
Step-by-step explanation:
The average number of words on the page is 300. Because there are 59,540 words and 59540/300 = 198.46 (approximately), there are 199 pages in the book (because the 0.46 pages would be the last page).

Explain what is the difference between radius
and circumference
Answer:
The circumference is the perimeter, specifically the perimeter of a circle. It can be solved by using the following formula:
C = 2πr
C stands for circumference.
π stands for pi, or 3.14 (rounded).
r stands for radius.
The radius is the distance from the center point of the circle to any point on the circle. It is denoted by the variable, r, as stated above. It is 1/2 of the diameter.
Answer:
the radius is the line from center to perimeter and circumference is the enclosed boundary
Step-by-step explanation:
radius- is any of the line segments from a circle or spheres center to its perimeter
circumference- the enclosed boundary a curved geometric figure, especially a circle
Please help me with this question, and show working out.
===============================================================
Explanation:
If you used scissors to cut a vertical slice down the lampshade, then it can be unrolled to form a rectangle.
The horizontal portion of this rectangle is the distance around the circle, which is the perimeter of the circle, or the circumference. That's C = 2pi*r. Check out the diagram below to see what I mean.
The diagram shows that the diameter is 20 cm, so the radius is half that at 20/2 = 10 cm.
The circumference is C = 2*pi*r = 2*pi*10 = 20pi cm exactly
The height of the rectangle is the height of the cylinder, which is h = 30 as shown in the diagram.
The area of the rectangle is length*height = (20pi)*(30) = 600pi square cm exactly.
If we were to use something like pi = 3.14, then its approximate area is 600*pi = 600*3.14 = 1884 square cm
Let's bump this up by 10%. To do so, we'll multiply by 1.10
1.10*1884 = 2072.4

O 13
O 36
Answer:
4 step by step explanation
The at {x} = 10, the value of the function remains +8.
What is function?A function is a relation between a dependent and independent variable. We can write the examples of functions as -
y = f(x) = ax + b
y = f(x, y, z) = ax + by + cz
Given is that the function f(x) is defined as -
f(x) = + 8
The given function is a constant function. This means that the value of the function remains the same irrespective of the value of {x} or the value in the function domain. So, at {x} = 10, the value of the function remains +8 only. This is true for all the values of {x}.
Therefore, the at {x} = 10, the value of the function remains +8.

Step-by-step explanation:
kendra revived a bonus that was 30%of her monthly earnings is her monthly earnings were 930 how much was kendras bonus
Hey there! I'm happy to help!
30% is the same thing as 0.3 because 0.3 is 30% of 1. If you multiply something by 1, it will just stay the same, so you need that percent of 1.
To convert a decimal to a percent, you move the decimal to the left two spaces.
Now, we simply multiply this by 930.
0.3×930=279
So, Kendra will receive a bonus of $279.

I need help with Shape equation puzzle 2 it’s due tomorrow
Hey there! I'm happy to help!
First of all, I would guide you to decipher clue 2 first. It is the only one that has just one shape, so then we can find the value of that shape.
To find what this circle is, we just divide 12 by three to see what 3 times the circle is!
12÷3=4
CIRCLE=4
-----------------------------------------------------------------
Now, let's look at clue one. This one only has two shapes, and it has the circle, which we already know.
We know that our circle is 4, so 5 circles will be 20.
This means that the diamond plus two will be 20, so let's just subtract 2 from 20!
20-2=18
DIAMOND=18
-----------------------------------------------------------------
Finally, let's look at the third one. This one is the trickiest. Two circles is eight, and that is going to be equal to our diamond (eighteen) and two triangles.
How is that going to work?
The triangles make us go backwards! Otherwise known as negative numbers!
To get from eighteen to eight, we have to go back ten. Ten is going to be made up of two triangles, so we just divide ten by two so each triangle gets an equal amount.
10÷2=5
TRIANGLE=5
-----------------------------------------------------------------
Have a wonderful day and keep on learning! :D
An equation is formed of two equal expressions. The value of the Circle, Diamond, and the triangle is 4, 18, and -5, respectively.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Let the circle be represented by C, the diamond be represented by D, and the triangle be represented by T.
Now, the clues can be rewritten as,
D + 2 = 5(C)
3(C) = 12
2(C) = D + 2(T)
Since the second clue has only one variable C, let's solve it first,
3(C) = 12
C = 12 / 3
C = 4
Further, the first clue has two variables C and D, and the value of C is already known, therefore, solve it second.
D + 2 = 5(C)
D + 2 = 5(4)
D + 2 = 20
D = 20 - 2
D = 18
Furthermore, by solving the last Clue we will get,
2(C) = D + 2(T)
Substitute the known values,
2(4) = 18 + 2(T)
8 = 18 + 2T
8 - 18 = 2T
-10 = 2T
T = -5
Hence, the value of the Circle, Diamond, and the triangle is 4, 18, and -5, respectively.
