Answer:

  1. -17.9
  2. 2n -7.4

Step-by-step explanation:

In each case, the only "like" terms are the constants. They are added together in the usual way.

1. -2.8 +0.9 -12 -4 = 0.9 -(2.8 +12 +4) = 0.9 -18.8 = -17.9

2. 2n +5.5 -0.9 -8 -4 = 2n +5.5 -(0.9 +8 +4) = 2n +5.5 -12.9 = 2n -7.4

There are 25 questions on your math test. You have completed 5 questions so far. What fraction of the total questions do you sti
maksim [4K]

Answer:

\frac{4}{5}

Step-by-step explanation:

If you have completed 5 questions, you still have 25-5=20 more questions to answer. We need to find what fraction 20 is of 25, if that makes sense. A fraction is simply a part over a whole. In this case, the part is 20 and the whole is 25. Therefore, the fraction we are looking for is \frac{20}{25}, which simplifies to \frac{4}{5}. Hope this helps!
