Answer:
55
Step-by-step explanation:
Add the numbers 5 + 8 and you get 13. Multiply 13 x 2 which is 26. Add 33 + 26 and you get 59. Then, subtract it by 4 and you get 55.
Let L be the length
Let w be the width
Let p be the perimeter
L+w+L+w=p
L=w+20
3L+2w+3L+2w=240
Sub the first equation in for L in the second equation and solve for w
3(w+20)+2w+3(w+20)+2w=240
3w+60+2w+3w+60+2w=240
10w+120=240
10w=240-120
10w=120
W=120/10
W=12
Sub w into the first equation and solve for L
L=w+20
L=12+20
L=32
Hope this helps!
Answer:
7 1/8
Step-by-step explanation:
Assuming that the first 13 was a mistake then the equation would be 13 1/2 + 2n = 27 3/4
subtrace 13 1/2 from 27 3/4
14 1/4
divide by 2
7 1/8
