Question

After dropping 5*F the temperature was 25*F. Create and solve an equation to show the starting temperature.

Steps:
1. Variable-
2. Coefficient-
3. Constant-
4. Equation-

Answer 1

30°F

Explanation:

Let the starting temperature be: x°F

After dropping 5°F, the expression becomes.

`x - 5`

The resulting temperature was 25°F

This means:

`x - 5 = 25`

The variable is x.

The coefficient of the variable is 1.

The constants are -5 and 25

The equation is

`x - 5 = 25`

We now add 5 to both sides to get:

`x = 25 + 5`

`x = 30`

Therefore the initial temperature is 30°F
