The answer is 2(3x-y)+5(x+2y).
Answer:
27, you need to simplify both sides of the equation to get x on one side.

Answer:
Decreased by 20%.
16 lbs is 80% of 20 lbs.
Step-by-step explanation:

y × 20 = 16 × 100
20y = 1600
20y ÷ 20 = 1600 ÷ 20
y = 80
100% - 80% = 20%

Answer:
Not a right triangle
Step-by-step explanation:
We can figure out if it is a right triangle or not by using the pythagorean theorem.
a^2 + b^2 = c^2
In this case a and b are 16 and 18
In order for it to be a right triangle, c has to equal 34, in this problem.
16^2 + 18^2 = c^2
= 580^2
=
= 24.0832
Since 24.0832 does not equal 34, this is not a right triangle
