Answer:
$10
Step-by-step explanation:
The hardcover books are $12 each which would be $60 out of the $100. There are four more paperbacks meaning they would be $10 each and cost $40 total.
I hope this helped!!! :)
That angle would also be 45
Just subtract the smaller volume from the larger:
10 × 10 ×15 - 7 × 9 × 12
First you would multiply 10 × 10 × 15 = 1500 and then multiply 7 × 9 × 12 = 756.
After you would subtract 1500 - 756 which would give you 744
I hope that helped!
3(5y-6)-2y=8
15y-18-2y=8
13y-18=8
13y=26
y=2
That is because you have the expression you can substitute it on the system.( hope this helps)
