Answer:
16
Step-by-step explanation:
(3x +3) + (5x-2) + (3x+3) =180
3x +3 + 5x-2 + 3x+3 =180
11x +4=180
11x =180-4
11x=176
x=176/11
x= 16
Answer:
x = 20
Step-by-step explanation:
This is a 30-60-90° triangle, so the side length measurements will follow the rule of 1, √3 , 2.
You are solving for the hypotenuse (2), and you are given the side (1). Multiply it by 2:
10 x 2 = 20
x = 20.
If you need to solve for the third side, it is the same. Multiply this time by √3:
10 x √3 = 10√3.

If a 1.8 ounce jar costs $4.05, you want to do $4.05 divided by 1.8. That will give you the cost per ounce.
$4.05 / 1.8 = $2.25 per ounce.
