What is a correct method of solving the equation x/-8 - 7 = 12 for x

1 answer:

7 0

Now, I'm not sure if this is correct but I think you have to get 'x' by itself, by adding 7 to both sides and then multipying (-8) to both sides.

if something is on sale for 35% off the original price and the sale price is 2.73, what is the original price?

Troyanec [42]

$4.20, 2.73/65 >>> .042 x 100 >>> answer.

Bonus:
To check it you'd do 4.20/20, then multiply .21 by 13 (65% divided into 5% portions = 13 portions) and your answer will be $2.73.

What is the length of Line segment S R?

tangare [24]

Using Pythagorean theorem.
16^2 + (RT)^2 = 20^2
256 + (RT)^2 = 400
(RT)^2 = 144
RT = 12

Using altitude theorem to find ST:
16/12= 12/ST
16ST = 144
ST = 9

Using Pythagorean theorem again:

12^2 + 9^2 = SR^2
144 + 81 = SR^2
225 = SR^2
SR= 15

Final answer: SR= 15

Hope this helps!
