Answer:
3,150.
Step-by-step explanation:
- 2 · {[ 5 · ( 60 - 2 )] + 25 } · 5.
- 2 · {[ 5 · ( 58 )] + 25 } · 5.
- 2 · { 290 + 25 } · 5.
- 2 · { 315 } · 5.
- 630 · 5.
- 3,150.
These are all of the steps to completely and correctly solve this question.
Hope this helps.

Answer:
6 $10 bills
Step-by-step explanation:
First you have to make a system of equations like such
5x + 10y = 150
x + y = 24
Now you can use any strategy to simplify it but I'll use multiplication and the subtraction:
5x + 10y = 150 - 5x + 5y = 120 = 5y = 30 this simplified is y = 6. You then substitute 6 for y in either equation. x + 6 = 24 and make it on opposite sides. x = 18.
So 18 $5 bills and 6 $10 bills
Answer:
B
Step-by-step explanation:
The area between the curves y = d and y = f(x), between the limits x=a and x=b, is:
∫ₐᵇ (d − f(x)) dx
Alternatively, the area between the curves x = f(y) and x = a, between the limits y = c and y = d, is:
∫ᵈ (f(y) − a) dy
Answer A would give you the area between x = f(y) and the y-axis. It needs to include the − a term to be correct.
