Answer: D. a+2s=$22
a+3s=$28
Step-by-step explanation:
Let's take a look at our variables. They are a and s, the a standing for the cost of an adult ticket and the s standing for the cost of the student ticket. In both situations, only one adutl ticket was purchased, so we start off out equations with only an a. As for the student tickets, Alex buys 2 and Jen buys 3.
a+2s
a+3s
The whole point of writing this equation is to find the cost of the tickets, so we would both equal it to the amount they spent.
a+2s=$22
a+3s=$28
Answer: 2( 7x - 4 )
Explanation:
First let’s distribute the 4 to (3x - 2) by multiplying each term by 4.
2x + 4(3x - 2) =
2x + 4 • 3x - 4 • 2 =
2x + 12x - 8
Next we combine like terms:
2x + 12x - 8 =
14x - 8
None of the answers without parenthesis match the formula above so I will factor out a 2
14x - 8
= 2( 7x - 4 )
Notice how I factored out the 2 putting the result of dividing the equation by 2 inside the parenthesis and then moving a 2 to the outside of the parenthesis.

16 : 80
x : 100
Cross multiply.
80× = 100×16
× = 100 × 16 /80
× = 20 grams.
