Answer:
Number of 5 dollar bills = 23
Number of 10 dollar bills = 13
Step-by-step explanation:
Let number of 5 dollar bills be x
and the number of 10 dollar bills be y
Total $245, means we can write:
5x + 10y = 245
Ten more 5 dollar bills than 10 dollar bills, means:
x - 10 = y
Now we substitute 2nd equation in first and solve for x:

Also,
y = x - 10
y = 23 - 10 = 13
So there are 23 5-dollar bills and 13 10-dollar bills

Answer:
18 Laptop models were sold.
Step-by-step explanation:
27/3=9
9*2=18
16 and 17. area is given. A=

use this relation to find radius
18.base=2, h=3.8 so, area=(1/2)*base*h=3.8 thats option D
19. area= base*h=12*7=84 option B
20.area of trapezoid= (1/2)h(a+b) where a and b are parallel sides.
so, area=(1/2)(3)(8.9+3.3)=(1/2)(3)(12.2)=3*6.1=18.3 option D
