Billy has a gift card with a $145 balance. He buys several video games that cost $45 each. After the purchases, his gift card balance is $10. Enter an equation to help find out how many video games Billy bought.

Equation is  145 - 45 x = 10.

Billy bought 3 video games.

Step-by-step explanation:

As given,

Total Balance in the gift card = $145

The cost of each video game = $45

After purchasing , Balance in Gift card = $10

Now,

Let Total number of  video games Billy purchase = x

⇒Cost for video game = 45x

Now,

As we know ,

Total Balance - Purchased Item = Balance left

⇒ 145 - 45 x = 10

∴ The equation is 145 - 45 x = 10

Now,

145 - 10 = 45x

⇒135 = 45x

⇒ x = = 3

∴ we get

Billy bought 3 video games

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
