Answer:
i think x is 55
Step-by-step explanation:
.25(x-13)=17
.25x-3.25=17
.25x=13.75
x=55
x=41
0.25(x-13)=7
We move all terms to the left:
0.25(x-13)-(7)=0
We multiply parentheses
0.25x-3.25-7=0
We add all the numbers together, and all the variables
0.25x-10.25=0
We move all terms containing x to the left, all other terms to the right
0.25x=10.25
x=10.25/0.25
Length = 2x - 5
Width = x
Perimeter = 146
P = 2L + 2W
146 = 2(2x - 5) + 2x
146 = 4x - 10 + 2x
146 = 6x - 10
146 + 10 = 6x
156 = 6x
156/6 = x
26 = x
Length = 2(26) - 5
Length = 52 - 5
Length = 47 cm
Width = 26 cm

67°
Angles on a straight line add to 180, so:
A + D = 180
D = 180 - A
D = 180 - 113
D = 67
$3.11
you have to subtract 24.10 from 22.99
