Answer:
The equation is 1/2 x + 8 = 15 ⇒ answer A
Step-by-step explanation:
* Lets explain how to solve the question
- Grace and her dad are planning to attend the state fair
- The price of an adult ticket is $15
- The price of the adult ticket is one half the price of the student ticket
plus $8
- Assume that the price of the student ticket is x
∵ The price of the student ticket is x
∵ The price of the adult ticket is half the price of the student ticket
x plus 8
- lets multiply half by x and then add the result by 8
∴ The price of the adult ticket = 1/2 x + 8
∵ The price of the adult ticket is $15
- Equate the expression of the price of the adult ticket by the price of
the adult ticket
∴ 1/2 x + 8 = 15
* The equation to determine how much Grace will pay for a student
ticket is 1/2 x + 8 = 15
∴ The answer is choice A
Answer:
3,-4
Step-by-step explanation:
im not sure if this is right or not but I tried
First, use distributive property:
5(2r+6)-12r <em>The original expression; multiply 5 by 2r, and 5 by 6.</em>
10r+30-12r <em>Keep the -12r, just add it on to the end of the number(s) you found</em>
Next, use communitive property:
10r+30-12r <em>What we found in the previous step</em>
-2r+30 <em>Combine the like terms; 10r-12r=-2r, then place the 30 at the end</em>
Done! Your answer is -2r+30.
Hope that helps!
