Answer:

Each pound of chocolate chips costs $ 1.5 and each pound of walnuts cost $ 3.75 .

Step-by-step explanation:

Let, each pound of chocolate chips costs $ x and each pound of walnuts costs $ y.

Then, according to the question,

5x + 6y = 30 --------------(1) and,

3x + 2y = 12 ----------------(2)

Multiplying (2) by 3 we get,

9x + 6y = 36 ---------------------(3)

Deducting (1) from (3) we get,

4x = 6

⇒ x = 1.5 ----------------------(4)

From (4), putting the value of x in (2) , we get,

2y = 7.5

⇒ y = 3.75 ---------------------------(5)

Constance's car has a 12-gallon gas

antiseptic1488 [7]

Answer:

7.5 hours

Step-by-step explanation:

Constance's car has a 12-gallon gas tank.

She can travel 25 miles on one gallon of gas, so she can travel

$25\cdot 12=300$ miles using all gas from the tank.

Constance begins with a full tank of gas and drives at a constant rate of 40 miles per hour.

So, Constance can drive for

$300 : 40=7.5$ hours.
