<h2><u>EQUATION</u></h2><h3>Exercise: -30 = 5(x + 1)</h3>
First, apply the distributive property:
-30 = 5(x + 1)
-30 = 5x + 5
Substract 5 from both sides:
-30 - 5 = 5x + 5 - 5
-35 = 5x
Divide both sides by 5:
![\mathsf{\dfrac{-35}{5} = \dfrac{5x}{5}}](https://tex.z-dn.net/?f=%5Cmathsf%7B%5Cdfrac%7B-35%7D%7B5%7D%20%3D%20%5Cdfrac%7B5x%7D%7B5%7D%7D)
![\large{\boxed{\mathsf{-7 = x}}}](https://tex.z-dn.net/?f=%5Clarge%7B%5Cboxed%7B%5Cmathsf%7B-7%20%3D%20x%7D%7D%7D)
Let's check the answer:
-30 = 5(x + 1)
-30 = 5(-7 + 1)
-30 = 5(-6)
-30 = -30
The answer is correct.
<h3><u>Answer</u>. The value of x = -7.</h3>
Answer:
It's not A, B, or D. So, the best choice would be, C. Lisa, because there will be variability in the responses collected.
Answer:
Step-by-step explanation:
The surface area of a sphere with radius r is given by
S = 4 pi r^2
for a radius of 11 units,
S = 4 pi 11^2 = 484 pi = 1520.5 sq. units
This does not correspond to any of the answers.
Please check question.
Answer: 18
Step-by-step explanation: 9 x 12 x 7.5 = 810
since it is inside out 810 x 2 = 1620
1620 divided by 90 = 18
Hope this helps
