Answer:
Kameron has 5 quarters in his wallet
Step-by-step explanation:
Let
x----> the number of nickels
y----> the number of quarters
remember that
1 nickel=$0.05
1 quarter=$0.25
we know that
x=3y -----> equation A
0.05x+0.25y=2
Multiply by 100 both sides
5x+25y=200
Simplify
x+5y=40 -----> equation B
Substitute equation A in equation B
(3y)+5y=40
8y=40
y=5 quarters
x=3(5)=15 nickels
Answer:
The answer is A
Step-by-step explanation:
i just got it right
Assuming that you mean that the sector is 7/16th of the area, we know that there are 360 degrees in a circle. To find 7/16th of that, we can simply multiply 360 by 7/16 to get 157.5 as the measure of the sector's arc in degrees
49b^2 -36 = (7b -6)(7b +6)
so because there you missed some signs in these wrote choices
