What’s b = 3x + 9xy ? solving the equation for x.

x= .

Step-by-step explanation:

Given :  b = 3x + 9xy.

To find :  Solving the equation for x.

Solution : We have given

b = 3x + 9xy.

Taking common 3x from right hand side

b = 3x ( 1 + 3y).

On dividing both sides by 1 + 3y .

= 3x

On dividing both sides by 3

= x .

Therefore, x = .

1/4 because there is 4 grades.

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
