Answer:
There are 6/5 white, 2 green, and 14/5 black
Step-by-step explanation:
Think of it like this.
First we add up everything.
3x+5x+7x = 6kg
15x=6
We find x and plug it in to the equation.
x=2/5
3*2/5=6/5 (6/5 is white)
5*2/5=2 (2 is green)
7*2/5=14/5 (14/5 is black)
There are 6/5 white, 2 green, and 14/5 black
Answer:
x = 9/4 or 2.25
Step-by-step explanation:
First you will combine like terms. Combine 2x + 3x - x which gives you 4x. Then combine 9 - 2 and you get 7. Now the equation is 4x + 7 = 16. Subtract 7 from both sides to get x by itself. Now you have 4x = 9. To find what x equals, divide by 4 on each side. x = 9/4 or 2.25
