Answer:

1=n

Step-by-step explanation:

Step 1- Distribute into the parenthesis.

7(3)+5(3)n= 6n+1(6)+4(6)n

Step 2- Multiply

21+15n= 6n+6+24n

Step 3- Add common variables to simplify.

21+15n= (24n+6n)+6

21+15n= 30n+6

Step 4- Subtract the smallest variable to both sides.

21+15n= 30n+6

   -15n  -15n

21= 15n+6

Step 5- Subtract 6 to both sides.

21= 15n+6

-6           -6

15= 15n

Step 6- Divide both sides by 15.

<u>15</u>= <u>15n</u>

15   15

1=n

THE answer I need some help i do not get it
mamaluj [8]
Hi, AlaynaSanjurjo!
All we need to do is multiply 93 by 3, then divide it by 9. Since we have 3 boxes, and 93 tangerines in each box, we have to add them all up and divide them equally. I am sure you are capable of doing the equation now.
93 * 3 / 9

I hope I helped!

~Olivia

(P.S. I am working for Virtuoso and many don't consider giving others brainliest answers, but could you give me one? I need two more!)

Mumz [18]

Answer:

21/8 or 2 5/8

Step-by-step explanation:

7/2 miles is equal to 3 1/2 mile trail, or also a 3 2/4 mile trail. You then multiply 3 2/4 and 3/4 and get 2 5/8 or 21/8.
