Answer:
Let x = the number of quarters
Let y = the number of nickels
X + y = 62 x = 62 - y
.25x + .05y = 12.50 Multiply both sides of the equation by 100 to get rid of the decimal points.
25x + 5y = 1250
25(62-y) + 5y = 1250
1550 - 25y + 5y = 1250
-20y = -300
y = 15 nickels
x = 62 - y = 62 - 15
x = 47 quarters

Answer:
11+x^2/3
Explanation:
“Eleven more” means you add 11 somewhere in the expression.
11+
The “quotient” is the answer to a division problem, so “the quotient of a number squared and three” translates to the answer to a number squared divided by 3.
11+x^2/3
“A number” in the question would be x, because it’s the unknown value.
I hope this helps!
