On the third step it adds 8 on both sides. You are suppose to subtract 8 on both sides.
A more accurate method for approximating the volume of the spherical slab other than using just cylindrical slabs is the; use the cross sections of the actual sphere, and to not use the cylindrical slabs.
<h3>What is a Cylinder?</h3>
A Cylinder is a surface created by projecting a closed two-dimensional curve along an axis intersecting the plane of the curve.
Sphere
This is a regular three-dimensional object in which every cross-section is a circle; the figure described by the revolution of a circle about it's diameter.
Therefore, the use of cross sections of the actual sphere is a more accurate method for approximating the volume of the spherical slab.

x
Answer:
x = 16
∠A = 39
∠B = 54
∠C = 87
Step-by-step explanation:
Make a equation of all of the angles added together is equal to 180 since the angles of a triangle added together is 180
(4x-10)+(2x+7)+(7x-25)=180
combine like terms
4x+2x+7x-10+7-25 = 180
13x-28=180
solve for x
13x=208
x = 16
plug in x to find the measure of the angle
∠A = 2(16) + 7 = 39
∠B = 4(16) - 10 = 54
∠C = 7(16) - 25 = 87
Add them together to double check your answer
39 + 54 + 87 = 180

Answer:
y = 2x+5
Step-by-step explanation:
Add y on both sides, this cancels out the y on the left side
add 2x and add 5 on both sides, this cancels out the -2x and the -5 on the left side.
<u>OR </u>
Divide/Multiply both sides by -1, as it will cancel out the negatives as two negatives make a positive.
If you needed a value for y, more info is needed.
