Answer:

4. -32

5. x= 10

6. x=3

7. x= 1

8. x=2

9. x=-6

Step-by-step explanation:

For every single equation, you equal it to 180, then for the two angles you have, you add them together. Then you subtract whatever the total is for the added angles from 180, Then you divide by the number in front of x on both sides and you get your answer.

125+25+-5x=180

(add like terms)

150+ -5x= 180

(Subtract 150 from both sides.)

-5x = 30

(Divide by -5)

x=-6

<h3>How to work with place values?</h3>

In any number, the place value refers to the "place" that a digit has on a number. The first one is the units place, the second is the tens place, and so on.

As more in the left is the place value, the largest value it represents.

Particularly, in 145,317

The 3 is on the third place, so it represents the value 300.

For example, in 143,417

The 3 is more in the left than before, this time on the fourth place, this time the value of the 3 is 3,000.

Then, a number where the digit 3 has a value ten times greater than the 3 in 145,317 can be 143,417.
