Given line l and line M are parallel. Find the value of x and y.

Liula [17]

Answer:

x = 4

y = 10

Step-by-step explanation:

29x - 3 + 15x + 7 = 180 (Linear Pair)

44x + 4 = 180

44x + 4 = 180 - 4

44x = 176

$\frac{44x}{44} = \frac{176}{44}$

x = 4

29(4) - 3

116 - 3

113

13y - 17 = 113 (Alternate Exterior Angles Theorem)

13y - 17 + 17= 113 + 17

13y = 130

$\frac{13y}{13} = \frac{130}{13}$

y = 10

If 2 liters of sea water contain 70 grams of salt, how much salt is in 32 liters of sea water?

OLga [1]

Answer:

1120 grams

Step-by-step explanation:

The amount of sea water is directly proportional to the amount of salt in the water.

Let the amount of sea water be W and the amount of salt be S.

This means that:

W α S

=> W = kS

where k = constant of proportionality

2 liters of sea water contain 70 grams of salt Therefore:

2 = k * 70

k = 2 / 70 = 1/35

Therefore, for 32 liters of sea water:

32 = 1/35 * S

S = 35 * 32

S = 1120 grams

There are 1120 grams of salt in 32 liters of water.
