Answer:
W = 15 ft. and L = 30 ft.
Step-by-step explanation:
Perimeter = 90 ft.
Twice as long as it is wide: L=2W
P = 2(L + W) = 2(2W + W) = 6W
90 = 6W
W = 15 ft. and L = 30 ft.
Answer:
x = 48
Step-by-step explanation:
First find y
52+y+59 = 180 since they from a straight line
y = 180-59-52
y = 69
Then we know the angles of a triangle add to 180
x+y+63 = 180
x+69+63 = 180
x = 180-69-63
x =48
Answer:
(-2,-110)
Step-by-step explanation:
First solve for x
20x−70=70x+30
x= -2
Now substitute x for -2
y=20x−70
y=20(-2)-70
y = -110

Answer:
$14.42
Step-by-step explanation:
Price of Album - $17.00 * .20 = 3.4 (this is the discount)
Then subtract 3.40 from 17.00 to get 13.60
Add the sales tax in by doing $13.60 * 0.06 = $0.82
Add that to the 13.60 to get $14.42 for the total after discount and after tax.
