Answers
Answer:
2 sides are [tex]\frac{33}{13}[/tex] or 2.5
2 sides are [tex]\frac{47}{13}[/tex] or 3.6
Step-by-step explanation:
There must be 2 2x+3s and 2 3x+2s
The perimeter is the sum of the sides (it has 4 sides)
2(2x+3) + 2(3x+2) = 4(4x-5)
distributive property
2*2x + 2*3
4x+6
other one
2*3x + 2*2
6x+4
perimeter
4*4x + 4*-5
16x-20
together...
(4x+6) + (6x+4) = 16x-20
add like terms
10x+10 = 16x-20
add 20 to both sides
10x+30 = 16x
subtract 10x from both sides
30 = 26x
divide by 26 on both sides
[tex]\frac{30}{26} = x[/tex]
simplify
[tex]\frac{15}{13}[/tex]
Substitute the x value
2 of the sides are 2x+3
so
[tex]2(\frac{15}{13} ) + 3[/tex]
[tex]\frac{30}{13} + \frac{3}{1}[/tex]
[tex]\frac{33}{13}[/tex]
or 2.5
other sides
[tex]3(\frac{15}{13} ) + 2[/tex]
[tex]\frac{45}{13} + \frac{2}{1}[/tex]
[tex]\frac{47}{13}[/tex] or 3.6

Answers
Answer:
[4]x+[8]=[1×]+2
Step-by-step explanation:
x will be negative now that the more x you have the higher your number will have to be.
The requried, x is negative, the left-hand side of the equation is positive, but the right-hand side is negative, so the equation has a negative solution as x = -3.5.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
One possible solution is,
[1]x + [2] = [3]x + [9]
To see that this equation has a negative solution, we can rearrange it to get:
x + 2 = 3x + 9
x - 3x = 9 - 2
-2x = 7
x = -3.5
Since x is negative, the left-hand side of the equation is positive, but the right-hand side is negative, so the equation has a negative solution.

7x + 2y = –1
7x + 2y = 1
14x + 4y = –1
14x + 4y = 1
Answers
Answer:
7x + 2y = 1
Step-by-step explanation:
1. Find the slope of the line.
(y2-y1)/(x2-x1) ----> (11 - (-3))/((-3) -1) ----> (11+3)/ (-3 -1) ----> 14/-4
*lets simplify into (7/-2)*
2. Write into slope intercept form.
y=mx+b (m is the slope) (b is the y intercept)
y = (7/-2)x + b
We now need to find the value of b, this can be done by plugging in values of x and y, and using algebra to solve.
11 = (7/-2)(-3) + b
11 = 10.5 + b
b = 0.5 or 1/2
slope intercept form y = (7/-2)x + 1/2
Now we convert to standard form: ax+by=c
*In this form we our a term cannot be a fraction nor can it be negative*
1. Get x and y on the same side, and since our x term is negative right now, we can make it positive by adding it on both sides.
(7/2)x + y = 1/2
2. We now want to get rid of the fraction in term a, so we multiply the entire function by two, so the denominator cancels out.
2(7/2)x + 2y = 2(1/2)
Simplify and you get
7x + 2y = 1

The equation which can be used .
We need to find the width of the garden.
Solution :
Now Length of the garden is given we will substitute in the given equation to find the width.
Now Using Subtraction property we will subtract both side by 30 we get;
Now Using Division Property we will divide both side by 2 we get;
Hence the Width of the garden will be 9 feet.

Step-by-step explanation:
Answer:
Hint(look at the first number in each part and math it with the first number in each answer.) For example, 3(937), the distributive property for that one would be 3(900) + 3(30) + 3(7). Then for 5(209) it would be 5(200) + 5(0) + 5(9), then for 6(342), it would be 6(300) + 6(40) + 6(2). Then for 9(821), it would be 9(800) + 9(20) + 9(1), and for the last one it would be 11(143), it would be 11(140) + 11(40) + 11(3). You basically distribute each amount into different place values.

which of the follwong is CLOSEST to The area of the shaded part of circle V?
Answers
Answer:
A
Step-by-step explanation:
The entire circle has an area of pi * r^2
r = 10
pi = 3.14
Area = 3.14 * 10^2
Area = 314 cm^2
But that is the whole circle. What is shaded is 1/4 of the circle which 314/4
which = 78.5 cm^2
Answer: A
Answer:
A) 78.5 cm^2
Step-by-step explanation:
1. To find the shaded part of the circle (1/4), we can use a formula similar to the one we use to find the area of a whole circle, but in this case, for the 1/4 part that's shaded: [tex]\frac{1}{4} \pi r^2[/tex]. Keep in mind that pi is approximated to 3.14.
2. (Solving)
Step 1: Plug in the values.
[tex]\frac{1}{4}(3.14)(10^2)[/tex]Step 2: Simplify.
[tex]\frac{1}{4}(3.14)(100)[/tex] [tex]0.785(100)[/tex] [tex]78.5[/tex] 78.5 cm^2Therefore, the answer is A) 78.5 cm^2.
