if you add 4 to it then you would get 8
25% off translates into 0.25($30) = $7.50 off.
A faster way to determine the sales price is to subtract 0.25 from 1.00 and then mult. the regular price by the result: sales price = 0.75($30) = $22.50 (answer)
Answer:

Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles given and equate to 180
4x - 13 + 15 + x + 18 = 180 ( simplify left side )
5x + 20 = 180 ( subtract 20 from both sides )
5x = 160 ( divide both sides by 5 )
x = 32
∠A = 4x - 13 = (4 × 32) - 13 = 128 - 13 = 115°
∠C = x + 18 = 32 + 18 = 50°
As a check : 115° + 15° + 50° = 180° ← correct
Answer:
It is $9.99 discounted off of the original price, and the sale price would be $39.96.
Step-by-step explanation:
49.95 × .20 (20%) = 9.99
49.95 - 9.99 = 39.96
Answer:
Step-by-step explanation:
I'll give a couple answers so you get the gist of things.
All you have to do is substitute 1/2 for x and 3/4 for y.
Ex - 30. x × y = 1/2 × 3/4 = 3/8
