Answer 2

The correct answer for each part is -

1. c. Minus, difference, take away

In this part, the first option states multiplication and second options states addition.

2. a. x, y

Both X and y are variable in the equation.

3. a. 2a - 8

Twice a number will be represented as : 2*a = 2a.

Decrease by eight will be represented as : 2a - 8.

4. c. 8 ÷ a = 2

On solving this equation for a, we can find out number of siblings of Joey.
