The answers are in the picture.
Please help.​

Answer 1

Last one

Explanation:

Let the number be q

22 less than the number: q - 22

Is 24

q - 22 = 24

q = 24 + 22

q = 46

Answer 2

D

Explanation:

We need to convert these words into mathematical expressions:

- "Twenty-two less than a number"; "less than" indicates that we need to use subtraction, and since it's "twenty-two less than", we have: -22. Let's say the "number" is q. Then, we have -22 of q, which is q - 22.

- "is twenty-four"; "is" in math always means "equal", so we need an equal sign with 24 next to it: = 24

Put this altogether:

q - 22 = 24

The answer is thus D.
