Question

-i need at least one of them answered to get the point-

1. In this hanger, the weight of the triangle is x and the weight of the square is y

a. Write an equation using x and y to
represent the hanger

b. if x is 6, what is y​

Answer 1

Answer:

a. Hanger represent Equation $3x-2y=0$

b. x = 6 and y = 9

Step-by-step explanation:

Given:

Weight of triangle is x

Weight of Square is y

a.Now according to figure shown which represents the hanger

$x+3y=4x+y$

Equating this equation we get,

$4x-x+y-3y=0\\3x-2y=0$

∴Hanger represent equation $3x-2y=0$

b. Now given x=6

Substituting the value of x in above equation we get,

$3\times6-2y=0\\18-2y=0\\2y=18\\y=\frac{18}{2}=9$

Hence x=6 and y=9
