Solve equation. Verify answer 14=-2w
notka56 [123]

Answer:

w = -7

Step-by-step explanation:

Isolate the variable, w. Note the equal sign, what you do to one side, you do to the other.

Divide -2 from both sides:

(14)/-2 = (-2w)/-2

(14)/-2 = w

Note that when you are dividing:

  • 1 negative & 1 positive sign will result in a negative answer
  • 2 negative sign will result in a positive
  • 2 positive sign will result in a positive

In this case:

(14)/-2 = -7

-7 is your answer for w.

Is 120% less than, more than or equal to 1

Divide 120 with 100

120/100 = 1.2

1.2 > 1 ∴ 120% is 'more than' 1
