Hey there!
Set up an equation. This would be 4+0.5x=12. You have to get x by itself, so subtract 4 on each side. You get 0.5x=8. Divide by 0.5 on each side to get x=16. Heidi purchased 16 tickets.
I hope this helps!
28! hope this helps, you just plug in 4 for x, and then multiply by two.
Answer:
No.The answer should be -4.1
Step-by-step explanation:
1+4(3x-10)-12
5(3x-10)-12
15x-50-12
15x-62
x=-62/15
x=-4.1

We are asked to find the two integers, given that they are consecutive, and their sum is 65.

- Consecutive integers are right next to each other, like 12 and 13. or 65 and 66.
Let the first integer be x, and let the second integer be x+1.
Their sum is 65. Let's set up our equation:

Combine like terms:

Subtract 1 from both sides of the equal sign:

Divide both sides by 2:

To find the second integer, subtract the first integer from the sum of the two integers:


The integers are: 33 and 32.
Hope it helps you out! :D
