The answer is D. 15pi ft cubed
Step-by-step explanation:
5x - 7 = 13
5x = 13 + 7
5x = 20
x = 20 ÷ 4 = 5
10x - 14
10(5) - 14 = 50 - 14 = 36
Answer:
2nd option
Step-by-step explanation:
2 3/8-1 3/10
19/8-13/10
190/80-104/80
86/80
43/40
1 3/40
Since 2 croissants = $3 we can work out that 1 croissant = $1.50
Multiply $1.50 by 31 and we get $46.50
Therefore 31 croissants is $46.50
