Answer:
$3.03
Step-by-step explanation:
7x + $3.60 = $24.81
Subtract $3.60 from both sides of the equation:
7x + $3.60 - $3.60 = $24.81 - $3.60
7x = $24.81 - $3.60
7x = $21.21
Divide each side by 7:
(7x/7) = ($21.21/7)
x = ($21.21/7)
x = $3.03

Answer:
Step-by-step explanation:
22/64→11/32
49/63→7/9
24/96→¼
51/75→17/25
17/68→1/4
28/36→7/9
1/3x - 2/3 = -18
1/3x = -18 + 2/3
x = -54 + 2
x = -52 answer
