The daily lowest temperature, in degrees fahrenheit, for a certain week are -2, -3, x, 2x, 4, 8. for the week, the sum of the temperatures was -7°f. what is the value of x?

-14/9

Step-by-step explanation:

Combine -2, -3, x, 2x, 4, 8.  We get -5 + 3x + 12.  This sum is -7.

Solve this equation for x:  3x + 7 = -7, so 3x = -14/3.

Then x is -14/9.

-4.7

Step-by-step explanation:

-2 + (-3) + x + 2x + 4 + 8 =  -7

                    -5 + 3x +12 =  -7

                            3x + 7 =  -7

                                  3x = -14

                                    x = -14/3 = -4.7 °F

The value of x is -4.7.

Check:

-2 + (-3) + (-4.7) + 2(-4.7) + 4 + 8 = -7

                      -5 - 4.7 - 9.3 + 12 = -7

                                               -7 = -7

OK
