Billy has a gift card with a $150 balance. He buys several video games that cost $ 15 each. After the purchases, his gift card balance is $45. Write an equation to help find out how many video games Billy bought. How many games he bought

(Gift card's original Balance - Balance after purchases)  Answer / cost of game

(150 - 45) = 105.     105/15 = 7

He bought 7 games

Step-by-step explanation:

You do the 150 - the 45 to see how much he had spent.

Divide by the cost and it shows how much he bought

v = (b - n)/p

if v = # of games; b = original balance; n = new balance; p = price per game

v = 7; billy bought 7 games

Step-by-step explanation:

v = (150 - 45)/15 = 105/15= 7

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
