The sum of the ages of Noi's and Noy's is 26 years. The different between four times Noi's age and two times Noy's age is 28 yea

nlexa [21]

Answer:

The age of Noi is 13.333 Years and the age of Noy is 12.67 years

Step-by-step explanation:

The given information are;

The sum of the ages of Noi and Noy = 26 years

Four times Noi's age - Two times Noy's age = 28

Let the age of Noi = X and let the age of Noy = Y

We have;

X + Y = 26 years.................(1)

4X - 2Y = 28 years.............(2)

Divide equation (2) by 2 to get;

(4X - 2Y)/2 = (28 years)/2 which gives;

2X - Y = 14 years.................(3)

Add equation (3) to equation (1), to get;

X + Y + 2X - Y = 26 years + 14 years

3X = 40 years

X = 40/3 = 13.333 Years

From equation (1), X + Y = 26 years, therefore;

Y = 26 - X = 26 - 13.33 = 12.67 years

Therefore, the age of Noi = 13.333 Years and the age of Noy = 12.67 years.

Answer:

A) 3 cups

B) $40.50

Step-by-step explanation:

Part A

Step 1 - divide the target number of pralines by the number the recipe makes:

108 ÷ 18 = 6

Step 2 - multiply this number by the amount of light cream in the recipe for one batch:

$\frac{1}{2} * 6 = 3$

This means that 3 cups are needed.

Part B

Step 1 - Divide the total pralines by 4:

108 ÷ 4 = 27

Step 2 - Multiply this number by the price Kia is going to sell them:

1.50 * 27 = 40.5

So she will make $40.50 for the school.

Hope this helps!
