We first need to find the sum of the interior angles in a pentagon, which you do by doing (5 - 2) × 180, which equals 3 × 180 = 540°. Now you know that all of the angles inside the shape must add up to 540, so you can make an equation:
90 + 112 + 2x + 148 + 2x + 10 = 540
360 + 4x = 540
- 360
4x = 180
÷ 4
x = 45

Answer:
666.667
Step-by-step explanation:
One ton weighs 2,000 lbs, so you divide 2,000 by 3.
480.
There is 1 before 8. And 1 is below not 5 or more in order to round up to 490. So, the only choice is to stay at 480. Therefore, the answer is 480.
Answer:
12x - 9y
Step-by-step explanation:
According to the distributive property:
3(4x - 3y) =
3*4x - 3*3y =
12x - 9y
