Answer:
y = x-4
Step-by-step explanation:
you can put it in a calculator to be sure
X = 21/35
x = 3/5
Explanation: divide both sides by 35 and reduce the fraction 21/35 to get 3/5.
Answer:
A. 432=18x
B. 22-see explanation
C. 24
D. See if your rounded answer and the actual answer are close.
Step-by-step explanation:
A. He buys a new phone for $432, and pays each month. We will use the variable x, and "x" will represent how many months he pays. It says that he pays $18 per month, so the equation would be 432=18x.
B. We need to isolate x, and to do this we have to divide 432 by 18. To approximate this answer, round 432 to 440 and 18 to 20. Now, divide 440 by 20. We get 22, so this will be the estimation.
C. Divide 432 by 18. We get 24.
E. You can see if it is reasonable if they are close in value.
Answer: The length is 24.5 feet.
Step-by-step explanation:
The formula for the perimeter of a rectangle is P = 2L + 2W.
Plug in the values you know
87 = 2L + 2(19)
Solve for L
87 = 2L + 38
subtract 38 from both sides
49 = 2L
divide both sides by 2
L = 24.5
