What value of a makes the equation true
Answer:
The correct answer is -2.
Step-by-step explanation:
it is -2 because if you replaced -2 with a you would have -2 minus 1.5 which is -0.5. -0.5 multiplied by 3 gets you -1.5.
Answer:
Step-by-step explanation:
3(a + 1.5) = -1.5
3a + 3*1.5 = -1.5
3a + 4.5 = -1.5
Subtract 4.5 from both sides
3a + 4.5 - 4.5 = -1.5 - 4.5
3a +0 = - 6.0
3a = - 6
Divide both sides by 3
3a/3 = -6/3
a = -2
Which is a solution to 2x + 1 = 21?
Answer:
x = 10 is your answer
- Explain -
Step 1: subtract 1 from both sides (subtraction of equality)
which will give us:
2x = 21 - 1
which equals to
2x = 20
Step 2: Divide both sides by 2
which is
2x/2 = 20/2
2/2 = 1 and 20/2 = 10
Therefore the answer is x = 10

What is Area?Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. The area of a plane figure is the area that its perimeter encloses. The quantity of unit squares whcihh cover a closed figure's surface is its area.
We have, Radius of semicircle = 2 in
So, Area of semicircle = πr²/2
= 3.14/2 x 2/2 x 2 /2
= 1.57 x 1 x 1
= 1.57 mm²
So, the area of the semicircle is 1.57 mm².
Therefore, Radius = 1 in

Which of the following equation have exactly one solution?
A) 58x + 52 = -78x - 78
B) 58x + 52 = 78x - 78
C) -78x + 52 = -52x - 78
D) 52x + 52 = 52x -78
Answer:
A, B, C all have one solution.
Step-by-step explanation:
1) Each equation in this question has one variable (x). This means that only one solution will be there.
2) Solve for x, you can cross out option D. When you subtract 52x from both sides, you're left with 52 = -78
Which is not true
3) Option A, if solved x = -65/68
4) Option B, x = 13/2
5) Option C, x = 5
All except D, have one solution, I don't know if it's a multiple choice answer but this is how I can help.
Answer:
The answer is A, B, and C.

What is the exact circumference of a circle with a radius of 15 cm? 10πcm 15πcm 30πcm 60πcm WIIL GIVE BRAINLIEST
Answer:
(C) 30πcm
Step-by-step explanation:
In order to find circumference you use the formula C (circumference)=2(pi)(r) in which r is the radius. In this case, two and 15 are thirty so to find the circumference all you have is the equation 30 times pi centimeters is equal to the Circumference.
Answer:
37 pi
Step-by-step explanation:
The circumference of a circle is equal to pi times the diameter.
The formula for the circumference of a circle is C=pi d,and since d = 37 ,we know that C=37 pi.
37 pi =116.238928183,but pi is irrational and the decimal will never end.
Thus,the most exact way to express the circumference is 37 pi.

Subtract
(3x² + 7) – (3x - 2)
Answer:
3x^2 - 3x + 9
Step-by-step explanation:
you combine like terms. so the only things you can subtract is 7 - -2 which is actually 7 + 2. hope this helped
Answer:
(3x² + 7) – (3x - 2)= 3(x²-x+3)

3x² + 7- 3x - 2 -add 7 and 2 to get 9
3x²- 3x+9 -factor the common term which is 3
3(x²-x+3) -then here's you answer
You and two of your friends go to eat pizza together. There are two deals: 10% off of 1 pizza 30% off of 3 pizzas Do you want to each pay separately and get 10% off of your bill or do you want to split the bill 3 ways and get 30% off of 3 pizzas? Write a paragraph that convinces your teacher which one is the better deal. Show all of the math involved in your calculations.
Please help :(
Answer:
The first one is the better deal.
Step-by-step explanation:
The first one is the better deal =====
30% of 3 = 0.9
0.9 = 90
10% of 1 = 0.1
0.1 = 10
So the better deal would be 10% of 1

What type of function is represented in the table? x|0|1|2|3|4|5|
A exponential B logarithmic C linear D quadratic. y|-1|0|-3|-10|-21|-36|
Answer:
This may be wrong but im guessing it is B.logarithmic
Step-by-step explanation:
The type of function is Quadratic.
What is function?An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given that;
x 0 1 2 3 4 5
y - 1 0 - 3 - 10 - 21 - 36
As, we can see from the table ,
The first differences of the y-values are 1, 0, -3, -7, -11, -15, which are not constant.
However, the second differences are all equal to -4, which indicates that the function has a quadratic form.
Hence, the function is quadratic.

for a special 16 sided die, what is the theoretical probability for rolling a number less than 9?
Answer:
8/16
Step-by-step explanation:
there are 16 sides on the dice and there is only 8 number that are less than 9 so that makes it 8/16:)
Answer: There is a 8/16 chance of getting a number under 9.
Explanation: There is a total of 16 sides on the die. If you look at the die numbers 1, 2, 3, 4, 5, 6, 7, and, 8 are all numbers under 9. Which explains how there are 8 sides. Meaning 8 numbers are 8 sides and 16 total numbers are 16 total sides. Therefore the answer is 8/16.

44 is equal to 8 times a number minus 4. what is the number?
Answer:
6
Step-by-step explanation:
Let "a number" = x
44 = 8x - 4
Simplify. Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First add 4 to both sides:
44 (+4) = 8x - 4 (+4)
44 + 4 = 8x
48 = 8x
Isolate the variable, x. Divide 8 from both sides:
(48)/8 = (8x)/8
x = 48/8
x = 6
