Answer: m=1

Step-by-step explanation:

-19-6m= -m-40+16m

Add 40 to both sides then add 6m to both sides you’ll get: 21=21m

Divide my 21 and you’ll get your answer which is 1 :)

Answer:

m=1

Step-by-step explanation:

1st, distribute the -8 on the right side in the paranthesis.

-19-6m=-m-40+16m

Since the 8 is a negative, -2m x -8 = positive 16m

2nd, group the m's on 1 side, and numbers on the other.

-19+40= -m+16m+6m

40 becomes positive and 6m become negative as they switch sides.

3rd, simplify both sides.

21=21m

Finally, divide both sides by 21.

1=m

Good Luck!

Steps:

1. -19-6m=-m-8(5-2m) (Next, multiply 5 and -2m by -8.)

2. -19-6m=-m-40+16m (Next, group the #'s and m's together.)

3. -19+40=-m+16m+6m (Next, simplify both sides.)

4. 21=21m (Next, divide both sides by 21.)

5. 1=m

Your answer is m=1.

Since Jordyn and Teri have fewer rolls of kite string, they decide to tie their string together so their kite can fly higher. Wr

Question:

Jordyn, Teri, and Morgan are going to have a kite-flying contest. Jordyn and Teri each have one roll of kite string. They also each have 45 yards of extra string. Morgan has three rolls of kite string plus 10 yards of extra string. All the rolls of string are the same length. The girls want to see who can fly their kite the highest.

Since Jordyn and Teri have fewer rolls of kite string, they decide to tie their string together, so their kite can fly higher. Write at least two expressions to show how much kite string Jordyn and Teri have. Let x represent the number of yards of string on one roll.

Answer:

$y=x +45$
