Answer:

F = -22

Explanation:

Write the formula.

Then replace the variable C with -30 and calculate the result.

F = 1.8C + 32

Now we replace C with -30.

F = 1.8(-30) + 32

Now we calculate the value of the right side.

F = -54 + 32

F = -22

F = 1.8C + 32

C = -30

Plug -30 in for C in the formula:

F = 1.8(-30) + 32

First you must multiply 1.8 and -30 per the rules of PEMDAS

F = -54 + 32

Next you will add -54 and 32

When adding a positive number with a negative number you will act as if you are subtracting the two numbers, then take the sign of the largest number (disregarding the signs). In this case the largest number is 54 and its sign is negative. Your answer will have a negative sign.

F = -22

Hope this helped!
