x=21
Step-by-step explanation:
Answer:
13in
Step-by-step explanation:
Let the width be w
The length will be 8+w
(8+w)(w)=65
8w+w^2=65
w^2+8w-65
Use quadratic equation formula.
You will get two answers
w=5 or w= -13
Pick the answer that is more sensible.
It cannot be a negative number; hence use 5in
5in+8in= 13in
Answer:
1/2
Step-by-step explanation:
turn 2/7 into 4/14 then subtract that from 11/14 and you get 7/14 and the also can go as 1/2
The equation would be 4y=5x 4(x+15)=5x x+15=y
let x be the amount that Shelia deposits each time
let y represent the amount that Sherri deposits each time
4(x+15)=5x
4x+60=5x
-4x -4x
60=x
Check:
x+15=y 60+15=y y=75
4(75)=5(60)
300=300
Shelia deposits $60 each time.
