Question

1.) the sum of d and 13

Answer 1

Answer:

1.) d + 13

• Sum means addition, so use the + sign.

2.) 42 - 3x

• Difference means subtraction, so use the - sign. I chose the variable "x" to represent "a number."

3.) A number plus six squared

• The answer is different depending on parenthesis. Above is the answer for x+(6)^2.

4.) Six plus a number, all divided by another number

Answer 2

Answer:

1) The sum of d and 13:

$x=d+13$

2) The difference between 42 and three time a number:

$y=42-3z$

3) $x+6^2$

The sum of a number ($x$) plus six to the power of two.

4)$\frac{6+x}{y}$

The sum of six plus a number (x), all divided by y
