Answer:
x = 25 degrees
Step-by-step explanation:
All angles in a triangle should add up to 180 degrees. So to solve for x, set up an equation where all three angles added up equals 180.
180 = 99 + 56 + x
180 = 155 + x
25 = x
The unknown angle is equal to 25 degrees.
Expression (non-algebraic): 3+2
An equation: 2x +1 = 21
An inequality: 2x > 2+2
Answer:
960
Step-by-step explanation:
We need to find 1/5 of 4800, we will do:
4800/5=960
So 960 is our answer.
The answer would be A) $79.20
(220*.4).9 as 60 percent off means that the product is only 40 percent of its original value, furthermore, we multiply the entire thing by .9
Negative 3x over the power by four
