Find the value of x for which the lines rand s are parallel.
erastovalidia [21]

Answer:

x = 12

Step-by-step explanation:

<1 and the 142-deg angle are vertical, so m<1 = 142 deg

The angle measuring 3x + 2 and <1 are same-side interior angles. If the lines are parallel, then those two angles are supplementary.

3x + 2 + 142 = 180

3x + 144 = 180

3x = 36

x = 12

On the number line below, the letters a and b are the same distance from 0. What is a + b?
jolli1 [7]

Answer:

The answer here would be 0.

Step-by-step explanation:

If a and b are both equal distances from 0, then adding the together would equal 0. Since a is the inverse of b,  using any number and its inverse will show you why the answer is 0. For example, if b is 9 then a would be -9. Adding these together equals 0.

How do I get the answer to number 4
elixir [45]
Hello,

You have 7 balloons and in total, they cost 9.1. dollars. To find the unit price per balloon simply divide 9.1. by 7.

You'll get 1.3, OR 1.30. 

To check your answer simply use inverse operations. Multiply 7 by 1.3 or 1.30 (it doesn't matter); you'll end up with the starting value 9.1.

Thus, the unit price per balloon is $1.30.
