Add the expression (6x - 2y - 5) - (-5 + 9y - 8x)​
enyata [817]

<u>Answer: </u>14x - 11y

<u>Step by Step Explanation: </u>

  • Ignoring that first half, your first step is to distribute the subtraction sign

-(-5+9y-8x) —-> 5-9y+8x

  • Next, combine like terms
  • Your x terms, y terms, and regular numbers

6x-2y-5+5-9y+8x

6x+8x-2y-9y-5+5 (reorganizing terms so that they’re together can be helpful for some people, but it’s not necessary)

6x+8x = 14x, -2y-9y = -11y, -5+5 = 0/Cancel each other out

This leaves you with 14x-11y

The tires on your bicycle have a radius of 14 inches. How many rotations does each tire make when you travel 900 feet? Round you
Nezavi [6.7K]

Around  150 rotations

I rounded the radius to feet which is 1 foot. Then you have to get the diameter which is 1x2=2. The diameter is 2 feet. Now for the circumference, we multiply 2 by 3.14(which is pi). The answer to that is 6.28, and since we are rounding it, we get 6 feet. However, we are traveling 900 feet. Divide 900 by 6 and get 150.
