Let Aaron Height Be x
Aaron = x cm
Peter = x-15 cm
5(x)-2(x-15) = 525 cm
5x-2x+30= 525 cm
3x+30=525
3x=525-30
3x=495
x= 495÷3
x= 165 cm
Aaron Height = x = 165 CM
Peter Heigt = x-15 = 165-15 = 150 CM
1/4 =2/8+3/8 =5/8
1-5/8=3/8
Answer:
2 1/2 hours

Answer: Width: 3.5 Length:10
Step-by-step explanation:
width=x
length=2x+3
area=35
x(2x+3)=35
2x^2+3x=35
2x^2+3x-35=0
(2x-7)(x+5)=0
x obviously cannot be negative ,so x=3.5
