2(4 + 2x) ≥ 5x + 5
First, we will need to expand our problem. Expanding is basically removing the parentheses. To do this, we will look at the first part of the problem to begin with. 2(4 + 2x). Since parentheses usually mean multiplication, we can start with 2(4). So, 2 × 4 = 8. We'll do the same thing with 2(2), 2 × 2 = 4.

Second, our next step is to subtract 4 from each side. We are trying to get the variable (x) on one side of the problem by itself.

Third, we can now simplify (5x) + 5 - (4). I put parentheses around what we are going to focus on. Subtract 5x - 4 to get 1, which can be put as the variable (x). Now we have, x + 5.

Fourth, let's subtract 5 from each side now. This will set up 8 - 5 which equals 3.

Fifth, we can switch sides now to get the result of this problem.

Answer:
Answer:
15 5/8 in³ (=15.625 in³)
Step-by-step explanation:
recall
volume of cube = length ³
given length = 2 1/2 = 5/2 inches
volume of cube,
= (5/2) ³
= 5³ / 2³
= 125 / 8
= 15 5/8 in³
Answer:
The value of number is 82.5
Step-by-step explanation:
Given as :
Let The number = x
∴ 25.6 % of x = 21.12
Or, 25.6 × x = 21.12 × 100
Or, 25.6 × x = 2112
∴ x = 
i.e x = 82.5
Hence 25.6 % of 82.5 is 21.12 So , The value of number is 82.5 Answer
Answer:
3/7
Step-by-step explanation:
add 1/2 and 5/2=3, make /7 in to fraction: 3/7
= 3/7 - 1/2 x 2/3 + 1/3
multiply
= 3/7 - 1/3 + 1/3
cancel out the 1/3s
= 3/7
