5(2x - 8) + 15 = -15

1 answer:

7 0

First, you would follow PEMDAS, so the parenthasis are first. Since you can't subtract 2x and 8, you would distribute to 5. This would make the problem 10x-45+-15. They you would add 45, so that the problem would become 10x=30. Finally, you would divide the entire problem by 10 so that you isolate the variable x=3

A game increased in price by 1/2 . After the increase it was priced at £27. What was the original price of the game? (Hegarty Ma

lukranit [14]

Answer:

£18

Step-by-step explanation:

Let

x = original price of the game

Increase in price = 1/2

New price = £27

x + 1/2x = £27

2x+x/2 = 27

3/2x = 27

x = 27 ÷ 3/2

= 27 × 2/3

= 54 / 3

x = £18

Therefore, the original price of the game is £18
