Diana buys 5 sodas every week. Which of the following expressions shows the total number of sodas she buys in y weeks? 5y
y/5
5 + y
5 + 5y

5y

Step-by-step explanation:

because each week she buys five so you multiply 5 by however many weeks.

5y

Step-by-step explanation:

The reason it is 5y is because for every week, Diana buys 5 sodas which means you would have to multiply. For example, if you wanted to find how many sodas Diana drank in 7 weeks you would multiply 5(7) to get 35 sodas in 7 weeks.

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0

step-by-step explanation:

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
