Marta's jump rope is 10" shorter than four times the length of Dilbert's rope. If both their ropes laid together end to end and
sladkih [1.3K]

Answer:

Marta's rope is 94"

Step-by-step explanation:

D = dilberts rope length

M = marta's rope length

Marta's jump rope is 10" shorter than four times the length of Dilbert's rope

M = 4D-10

both their ropes laid together end to end and measured 120" long

M+D = 120

Substitute 4D-10 for M in the second equation

4D-10 + D = 120

Combine like terms

5D-10=120

Add 10 to each side

5D-10+10 =120+10

5D =130

Divide by 5

5D/5 = 130/5

D =26

Now we need to find M

M+D = 120

M +26 = 120

Subtract 26 from each side

M = 120-26

M = 94

Solve the equation a = m – n for the variable n.
MaRussiya [10]

Answer:

m - a = n

Step-by-step explanation:

<u>Step 1:  Subtract m from both sides </u>

a - m = m - n - m

a - m = -n

<u>Step 2:  Divide both sides by -1 </u>

(a - m) / -1 = -n / -1

-a + m = n

m - a = n

Answer:  m - a = n
