Step-by-step explanation:
1.(4,16) and (x,24)
4/16 = x/24
Now you will cross multiple to get a liner equation.
16x= 4×24
Now you will divide both sides by the coefficient of x which is 16.
16x/16=4×24/16
Now 16 will cancel 16 and the equation will be like this
x=4×24/16
Now 4 will cancel 16 to get 4 and the 4 at the the nominator will cancel 24 to get 6.
Therefore x = 6.
2.(3, 4) and (9, y)
3/4 = 9/y
cross multiple to get a linear equation.
3y = 4×9
Divide both sides by the coefficient of y.
3y/3=4×9/3
As a said before 3 will cancel 3 to make y stand alone.
y = 36/3
y = 12.
3.(3,18) and (x,30)
3/18 = x/30
18x = 3x30
18x/18 = 3×30/18
x = 5
Therefore x = 5.
4.(3,36) and (6,y)
3/36 = 6/y
3y = 6×36
3y/3 = 6×36/3
y = 216/3
y = 72
Therefore y = 72.
5.(3,39) and (x,65)
3/39 = ×/65
39x = 3× 65
39x/39 = 3×65/39
x = 5
Therefore x = 5.
