Answer:
9 nickels
Step-by-step explanation:
Set the number of pennies as x. The number of nickels would be 31 - x.
The pennies are worth x cents and the nickels are worth 5 * (31 - x), or 155-5x.
We are given that he has 67 cents, so:
x + 155 - 5x = 67
Solve.
-4x = 67 - 155 = -88
x = 22
Nickels are 31 - x, so the number of nickels he has is 9.
I hope this helps!
Answer:
46°
Step-by-step explanation:
The exterior angle marked 69° is the sum of the remote interior angles 23° and x. So ...
69° = 23° +x
x = 69° -23°
x = 46°
The number of people being served went from 6 to 24, so the serving quadrupled.
So multiply 2.5 by 4 and you get 10 pounds of apples.
Step-by-step explanation:
2(x + 5) + 6x = 8x + 10
2x + 10 + 6x = 8x + 10
8x + 10 = 8x + 10
Since this equality is true for any real values of x, there are infinitely many solutions for x.
