The line rises to the left so the slope is negative.
Slope = rise / run = (3 - 1) / (-4-3) = 2 / -7
Answer is -2/7 (A)
36 total children
Ratio of boys to girls is: 3:1
36/4 = 9 9 children to each part of the ratio
9 x 3 = 27 total boys
9 x 1 = 9 total girls

Step-by-step explanation:
We will have to expand first then we simplify.
<u>Expand</u>
You will have to distribute the 2 over the x & 7 and the 3 over the x & 1 respectively.
<u />
<u />
<u>Simplify</u>
You will have to add 2x & 3x together and 14 & 3 together.

Answer:
3n/8 +1=25
3n/8= 25-1
3n/8=24
Multiply both sides by 8 to clear the fraction on the left
3n=24x8
n=24x8/3
n=64
The correct question is
<span>Ellie made a cube-shaped cardboard box with side-length s. The area of cardboard she used is given by the formula A = 6s2, where s represents the side length of the cube.
Which equation correctly solves the formula for s?
we know that
</span>A = 6s²---------> clear the variable s
s²=A/6------> applying square root both members
s=√(A/6)--------> s=(1/6)*√(6*A)
<span>
the answer is
</span>s=(1/6)*√(6*A)
