The answer is x= -10. To get this answer you have to simplify both sides of the equation, distribute, and combine the like terms. The second step is to add 15/2x to both sides. Step 3 is to subtract 72 from both sides, then divide both sides by 3
Answer:
27
Step-by-step explanation:
the watch was alredy 19 seconds behind so you take 46 and subtract 19 and you get 27
A + c = 158......a = 158 - c
9.90a + 5.50c = 1265
9.90(158 - c) + 5.50c = 1265
1564.20 - 9.90c + 5.50c = 1265
- 4.40c = 1265 - 1564.20
-4.40c = - 299.20
c = -299.20/-4.40
c = 68 <=== 68 child tickets sold
