Answer and Step-by-step explanation:

Solve for m.

<u>First, distribute the 5.</u>

5 + 20m - 2m = -13

<u>Combine like terms.</u>

5 + 18m = -13

<u>Subtract 5 from both sides of the equation.</u>

18m = -18

<u>Divide by 18 to both sides of the equation.</u>

<u>m = -1 <- This is the answer.</u>

\large\mathfrak{{\pmb{\underline{\red{Step-by-step\:explanation}}{\red{:}}}}}

5 \: (1 + 4m) - 2m =  - 13

➼ \: 5  + 20m - 2m \:  =  \:  - 13

➼ \: 18m =  - 13 - 5

➼ \: 18m =  - 18

➼ \: m =  \frac{ - 18}{18}

➼ \: m =  - 1

\large\mathfrak{{\pmb{\underline{\blue{To\:verify}}{\blue{:}}}}}

5 \: (1 + 4 \times  - 1) - 2 \times  - 1 =  - 13

➼ \: 5 \: (1 - 4) + 2 =  - 13

➼ \: 5 \times ( - 3) + 2 =  - 13

➼ \:  - 15 + 2 =  - 13

➼ \:  - 13 =  - 13

➼ \: L.H.S.=R. H. S

Hence verified.

A coffee dispensary uses ⅘ of a barrel of coffee beans per batch of coffee they ship. Yesterday, the dispensary used 3 ⅕ of a ba
KengaRu [80]

Answer:

4 batches

Step-by-step explanation:

First, you need to convert the mix number into a single fraction:

3 1/5 = 16/5 total barrels of coffee beans used

This allows us to divide the numbers easier in the next step.

Next, because each batch uses 4/5 of a barrel of beans, you need to divide 16/5 by 4/5:

(16/5) / (4/5) = 16/4 = 4 batches

(The fives cancel out because they are the same divisor.)

I hope this helps!
