Which expression shows a sum of five terms? (3 points)
Sav [38]

Answer:

5 + x + 5 + x + x

Step-by-step explanation:

We are given 4 expressions and we have to determine which expressions shows a sum of five terms.

We use the process of elimination:

5(x + 5)

=5x+25  (distributing 5)

This contains sum of only two terms, <u>eliminate</u>.

5x

It contains only 1 term, <u>eliminate</u>.

5 + x + 5 + x + x

It contains 5 terms 5,x,5,x and x, <u>KEEP</u>!

5.

Only contains 1 term, <u>eliminate</u>.

With this said, were left with:

5 + x + 5 + x + x

Which is the correct answer! :)

Lamar hikes Trail B, which is 2 1/2. He stops every 5/6. How many stops does he make?
Dahasolnce [82]

Answer:

2

Step-by-step explanation:

To solve this equation, you need to convert 2 1/2 into an improper fraction:

2 1/2 = 5/2

Then, you convert this into 6ths:

5/2 = 15/6

Next, you divide 15/6 by 5/6:

15/6 / 5/6 = 3

Because Jamal wouldn't make a stop at the end (it wouldn't be considered a stop because he is done), you subtract 1:

3-1=2

The answer is 2 (hope this helps, sorry if i got it wrong)
