What is 4^2y-3^2=-5y+(-5+7) Please explain step by step i need this asap :/

dybincka [34]

y = 11/21

To solve this first evaluate the power (then calculate the sum):

$4^{2}$ y - $3^{2}$ = 5y + (-5 + 7)

16y - 9 = -5y + 2

Next Move terms (move variable to the left side and change its sign) (Move constant to the right side and change its sign):

16y - 9 = -5y + 2

16y + 5y = 2 + 9

Next Collect the like terms and calculate the sum:

16y + 5y = 2 + 9

21y = 11

Lastly divide both sides of the equation by 21:

21y = 11

y = $\frac{11}{21}$

Natalka [10]

$0.25 X 10,000 = $2500.
We now know what the total sales price per tile sold was $2500.

$3000
-$2500
=$0500

We now know that the flat fee was $500.

Therefore the equation describing the revenue of the tile from this sale in terms of tiles sold is y = 0.25x + 500
The answer is C)
