Answer:
6
Step-by-step explanation:
-11x-6=5
-11x=5+6
-11x=11
x=11/-11
x=-1
4x+10=4(-1)+10=-4+10=6
Let X = the number of pennies.
The number of nickels would be 2X
A penny is 0.01 and a nickel is 0.05
Now you have:
0.01x + 2(0.05x) = 8.80
Simplify:
0.01x + 0.10x = 8.80
Combine like terms:
0.11x = 8.80
Divide both sides by 0.11:
x = 8.80 / 0.11
x = 80
Pennies = X = 80 total pennies.
Nickels = 2x = 2 *80 = 160 nickels.
Answer:
number of children ticket sold = 70
number of adult ticket sold = 70 × 3 = 210
number of student ticket sold = 500 - 4(70) = 500 - 280 = 220
Step-by-step explanation:
A local theater sells out their show. They sell all 500 tickets for a total of $7920 .00 . The total number of ticket sold is 500.
let
Number of children ticket sold = a
Adult ticket sold = 3a
Student ticket sold = 500 - 3a - a = 500 - 4a
Total cost = 7920
7920 = 12(a) + 15(500 - 4a) + 18(3a)
7920 = 12a + 7500 - 60a + 54a
collect like terms
7920 = 12a - 60a + 54a + 7500
7920 - 7500 = 6a
420 = 6a
divide both sides by 6
a = 420/6
a = 70
number of children ticket sold = 70
number of adult ticket sold = 70 × 3 = 210
number of student ticket sold = 500 - 4(70) = 500 - 280 = 220
