Answer:
A.
Step-by-step explanation:
So lets say you have 10+2y=2x, first you subract 10 by both sides, now you got 2y=2x-10. Divide all the numbers by 2, and then you got y=x-5.
It depends on where you live. I’d supposed you live in the United States. The average minimum wage for all of United States is $9.73 dollars.

Step-by-step explanation:
1) Convert mixed numbers to decimal numbers dividing the numerator by the denominator and adding the result to Whole number part:
![21+0.75=21.75\\\\2+0.5=2.5](https://tex.z-dn.net/?f=21%2B0.75%3D21.75%5C%5C%5C%5C2%2B0.5%3D2.5)
The unit rate is:

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
