Answer:

The number is 4.

Step-by-step explanation:

The difference of twice a number and 12 is 2x - 12.

Multiplying by 5 gives 5(2x - 12)

So 5(2x - 12) = -20

Solving for x

10x - 60 = -20

10x  = -20 + 60 = 40

x = 40/10

x = 4.

Dot got a 75% on her test. She missed 12 questions. how many questions were on the test
AleksAgata [21]
Well, if it was out of 50, it would be 76%.

So the answer might be 50 questions total, but maybe there was 49 questions total.

I would probably go with 50 questions total.
