Answer:
2a+8
Step-by-step explanation:
X= 5.1x+11.3
Explanation : combine like terms which is 5.1x and 3x and you get the answer D!
Nothing. It would have to be 5 and 8 to be 13... Not 14 and it would be math. :)
Answer:
The third one, x+(x+1)+(x+2)=-21 because x, x+1 and x+2 are three consecutive numbers.
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
