Answer:
x = 25
Step-by-step explanation:
2x-20=30
First, isolate the term with x in it by moving everything else to the other side:
2x = 30 + 20
Simplify like terms:
2x = 50
Further isolate the x by dividing by 2 on both sides:
2x/2 = 50/2
The 2 cancels out on the left, leaving:
x = 25
Answer:
1. 54 square feet.
2. 24 square feet.
3. 78 square feet.
Step-by-step explanation:
1. Each side of cube 1 is 3 feet x 3 feet, so each side has an area of 9 square feet. Multiply by 6 sides and the area is 54 square feet.
2. 6s^2 = (6 x 2) x 2
(6 x 2) x 2
12 x 2
= 24
3. Just add the 36 and 24.
56 + 24 = 78

Answer:
look at the picture I sent
1/4q = 3w + 3...multiply both sides by 4
q = 4(3w + 3)
q = 12w + 12 <===
