Answer:
Number of $10 bills = 2
Number of $5 bills = 3
Number of $1 bills = 5
Step-by-step explanation:
Given:
Total amount = $40
Number of $10 bills = x
Number of $5 bills = x + 1
Number of $1 bills = x + 1 + 2 = x + 3
Find:
Number of each bills
Computation:
10(x) + 5(x+1) + 1(x+3) = 40
10x + 5x + 5 + x + 3 = 40
16x = 32
x = 2
Number of $10 bills = x = 2
Number of $5 bills = x + 1 = 3
Number of $1 bills = x + 3 = 5
There are 12 total people who enjoy reading (7+5), of which 5 don't ride a motorcycle. So the relative frequency of people that don't ride motorcycles is
.
(xy)⁷
=(x⁷)(y⁷)
This is the simplified term.
Answer:
142 in²
Step-by-step explanation:
We want to find the area of all the rectangles and add them up.
For the 2 small rectangles on the side, the area is 15 in for each of them because 5x3. The 2 thinner rectangles each have an area of 21 in because 7x3. The 2 largest rectangles each have an area of 35 in because 5x7.
Now we can add it all up.
15+15+21+21+35+35=30+42+70=142
answer :
A. 100
step by step calculation
exterior angle plus interior angle add up to 180 degrees
hence:
180-70=110
180-60=120
180-50=130
therefore 100 is not an exterior angle of that triangle
