Mom wants to make 5 lbs of the sugar syrup. How much water and how much sugar does he need to make 20% syrup?
Wittaler [7]

Answer:

Let x pound of the sugar to make 20% syrup.

As per the statement:

Mom wants to make 5 Ibs of the sugar syrup.

We have to find how much water and sugar does she need to make 20% syrup.

By definition of proportion; we have

\frac{x}{5} = \frac{20}{100}

Simplify:

\frac{x}{5} = \frac{1}{5}

Multiply both sides by 5 we get;

x = 1

Remaining = 5 -1 = 4 pounds of water

Therefore, 1 pounds of sugar and 4 pounds of water does she need to make 20% syrup.

Show all your work <br><br> What is m∠KNLm∠KNL?
docker41 [41]
<span>m∠KNL = m∠MNJ
3(x+14) = 5x + 2
3x + 42 = 5x + 2
2x = 40
  x = 20

</span>m∠KNL = 3(x+14)
m∠KNL = 3(20+14)
m∠KNL = 3(34)   
m∠KNL = 102
