Lesson Steps

Step Type Explanation Answer

1

Problem

Simplify:
\$ |12 - 31 | times | - 6 + 13 |\$

2

Step

Given expression is

\$ |12 - 31 | times | - 6 + 13 |\$

3

Step

To simplify the expression, let’s first calculate the absolute values:

\$ |12 - 31 | = | - 19 | = 19 \$

\$ | - 6 + 13 | = | 7 | = 7 \$

4

Step

Now, multiply these absolute values together:

19 \$ times \$ 7 = 133

5

Step

So, the simplified expression is

133

6

Choice.A

This is not correct because it is not the result of multiplying 19 and 7

291

7

Choice.B

This is incorrect because the differences' absolute values were multiplied, yielding 133, not 117

117

8

Choice.C

Correct as it simplifies the expression by calculating absolute values inside modulus signs and multiplying them

133

9

Choice.D

This is not correct because it suggests the result is 123, which is not the correct value after performing the multiplication

123
