Answer:
x = 34
Step-by-step explanation:
This is a straight line so the sum of angles must be 180°
4x + 20 + x - 10 = 180 add like terms
5x + 10 = 180 subtract 10 from both sides
5x = 170 divide both sides by 5
x = 34
To calculate each angle we replace x with the value we found
4x + 20 ➡ 4×34 + 20 = 156
x - 10 ➡ 34 - 10 = 24

Step-by-step explanation:
<h3>7.</h3>
The Commutative Property of Addition changes the order of the numbers but does not affect the sum.
<h3>8.</h3>
We will convert the values into decimals for simplicity.
Arranging from least to greatest:
<h3>9.</h3>
2 + ( -8 )
2 is on the number line.
When -8 is added to 2, the value decreases, and it moves 8 units to the left side.
The result is -6.
