(a) Kim x years old
Jordan x+7 years old
4(x+7)=200
An Equation That Could Be Used To Solve For Kim's Age , x Is 4x+28=200.
(b) 4x=200-28
4x=172
x=43
Kim Is 43 Years Old.
(c) x+7
=43+7
=50
Jordan Is 50 Years Old.
Diametre = 2 x Radius
Radius = 7
Circumference = 2πr
= 2x22/7x7
= 44
Let the two numbers be x and y
x + y = 5(x-y)
x + y = 5x -5y
6y = 4x
x= (6/4)y
x= (3/2)y
there the ratio is 3/2
True.
The y-axis of the f(x) must equal to the x-axis of g(x)
The x-axis of the f(x) must equal to the y-axis of g(x)
