What integer is equal to |-10| + |-20|

Please answer

30

Step-by-step explanation:

The absolute value function always gives a positive value, that is

| - a | = | a | = a

Given

| - 10 | + | - 20 |

= 10 + 20

= 30

|-10| + |-20| = 30

Step-by-step explanation:

Absolute Value

The absolute value of x, written |x| is a positive number that represents the distance from the origin and the number.

In practice, the absolute value is found writing the number without the negative sign, if present.

For example:

|-9| = 9

|76| = 76

|0| = 0

The given expression is

|-10| + |-20|

Calculate each absolute value separately:

|-10|=10

|-20|=20

Thus:

|-10| + |-20| = 10+20 = 30

|-10| + |-20| = 30

The value of x round to the nearest hundredth is:

We can find the value of x with the help of trignometric ratio.

Based on the figure the Hypotenuse corresponding to the angle x is: 13 units.

and the adjacent side corresponding to angle x is: 12 units.

Hence, we will use the cosine trignometric ratio in the given right angled triangle as follows:

Round to the nearest hundredth we have:
