Answer:

The weight one can dry to get 140 grams is 700 grams

Step-by-step explanation:

Fresh grapes looses 80 percent of it weight while drying . To get 140 grams of dried grape we need to know the weight of the fresh grape.

Let the fresh grape weight = y grams

80% of the fresh grape weight will be =  80/100 × y grams

The weight of fresh grape you should dry to get 140 grams = Fresh grape weight - 80% of the fresh grape weight

140 = y - 80/100 × y

140 = y - 0.8 y

140 = 0.2y

divide both sides by 0.2

y = 140/0.2

y = 700 grams

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
