The Skateboard club has 2 different colours of skateboards Blue and Red. Can you find the number of skateboards of each colour, if the total number of skateboards is 15, and their product is 44

Answers

Answer 1

Answer: 11 and 4 respectively

Step-by-step explanation:

Let's denote the number of skate board for each color by x and y.

x + y = 15 ......... i

x × y = 44 .......... ii.

From equation I

x = 15 - y ....... iii

Put equation iii into ii.

x × y = 44

(15 - y) × y = 44

15y - y² = 44

15y - y² - 44 = 0

y² - 15y + 44 = 0

y² - 11y - 4y + 44 = 0.

y(y - 11) + 4(y - 11) = 0

(y - 4) = 0. .

y = 0 + 4.

y = 4

(y - 11) = 0

y = 0 + 11 = 11

The colors have 11 and 4 colors of blue and red respectively
