X= number of nickels
3x= number of dimes
Each nickel is $0.05 and each dime is $0.10. Multiply each coins monetary value by the quantity of each. Add them equal to the total $9.10.
(0.05 * x) + (0.10 * 3x)= 9.10
multiply inside parentheses
0.05x + 0.3x= 9.10
add
0.35x= 9.10
divide both sides by 0.35x
x= 26 nickels
DIMES
3x= 3(26)= 78 dimes
CHECK:
(26 nickels * 0.05) + (78 dimes * 0.10)= 9.10
$1.30 + $7.80= $9.10
$9.10= $9.10
ANSWER: There are 26 nickels and 78 dimes.

Answer: 33°
Step-by-step explanation: Because Angles Q and R are supplementary, we can say 2x + x + 81° = 180°
3x + 81° = 180° Subtract 81° from each side
3x = 99° Divide by 3
x = 33°
Divide the price by the number of ounces.
=$1.99 ÷ 15 ounces
=$0.13
The price per ounce of the 15 ounce can is $0.13.
Hope this helps! :)
