Answer:
x=12
Step-by-step explanation:
1/2x - 5 = 10 - 3/4x ---> move like terms to the same side
1/2x + 3/4x = 10 + 5 ---> calculate
5/4x = 15 ---> multiply both sides by 4/5
x = 12
Answer:
O A. 
Step-by-step explanation:
Since two -x's are being used, x becomes positive!
2 = 1 + 1
2 = 2
Solution: (-1, 2)
Based on the calculations, the surface area (SA) of a cylinder is equal to: B. 2,813.44 in.²
<h3>How to calculate surface area of a cylinder?</h3>
Mathematically, the surface area (SA) of a cylinder can be calculated by using this formula:
SA = 2πrh + 2πr²
<u>Where:</u>
The dimensions of this new cylinder would be equal to:
Radius = 8 × 2 = 16 in.
Height = 6 × 2 = 12 in.
Substituting the given parameters into the formula, we have;
SA = (2 × 3.14 × 16 × 12) + 2 × 3.14 × 16²
SA = 1,205.76 + 1,607.68
SA = 2,813.44 square inches.
