Mathematics

11. The two angles are vertical angles, which mean they are equal to each other.

14x - 5 = 13x

Add 5 to both sides:

14x = 13x + 5

Subtract 13x from both sides:

x = 5

12.  The two angles are supplementary and when added together need to equal 180 degrees.

5x -20 + 3x = 180

Combine like terms:

8x -20 = 180

Add 20 to both sides:

8x = 200

Divide both sides by 8:

x = 200 /8

x = 25

How to do it? i dont really under stand
dybincka [34]

First, we want to ask "What number divided by 7 <em>is </em>800?" That'll give us a jumping off point to answer the rest of the question.

If dividing some number by 7 gets us 800, that means that <em>multiplying </em>800 by 7 should get us back that number. We find that 800 x 7 = 5600. The first number higher than 5600 is 5601, which, when divided by 7, gets us about 800.14, a number greater than 800. So the lowest whole number that makes the inequality ? ÷ 7 > 800 work is 5601.
