Answer:
When 3x/4 - 13 = -9, x² = 256/9.
Step-by-step explanation:
3x/4 - 13 = -9
Multiply the expression by 4.
3x - 52 = -36
Add 52 to both sides.
3x = 16
Divide both sides by 3.
x = 16/3
Knowing x, let's square it.
(16/3)²
Apply the power to fraction rule.
16²/3²
Evaluate the powers.
256/9.
24% because you would make a ratio like x/100= 2,160/9000. So basically the x is the percentage you need, 100 is just an easy factorable percent, and 2,160 is the wheat bread and 9000 is all the bread. Basically what you do with this ratio is you cross multiply. This means you multiply 2,160 by 100 and divide by 9000 and that’s your percent
Well lets try this step by step
270/2 = 135
the cube is six sided
the answer must be 5/10 or 50 percent
Answer:
Part A :
Part B: To isolate variable we first divided both sides by 2 to cancel out 2 on the right side. Then we subtracted from both sides to cancel out from the right side leaving alone on right side.
Step-by-step explanation:
Given:
Formula for the perimeter of a rectangle :
To rewrite the given formula in terms of the width .
Solution:
In order to rewrite the formula in terms of the width , we will isolate on one side.
We have:
Dividing both sides by 2.
Subtracting both sides by .
Part A :
Part B: To isolate variable we first divided both sides by 2 to cancel out 2 on the right side. Then we subtracted from both sides to cancel out from the right side leaving alone on right side.
Answer: 64
Step-by-step explanation:
