Answer:
First, put it into slope/intercept form so you can see what you've got.
"Slope/intercept form" is y = everything else .
So that means you have to take the equation you have and "solve it for 'y' ".
2y - 10x = 20
Add 10x to each side: 2y = 10x + 20
Divide each side by 2 : y = 5x + 10
And that's exactly the information you need to graph it. On your graph,
mark a little dot on the y-axis at 10, and draw a line through that dot
with a slope of 5.
Answer:
pick a group of 3 randomly: 10C3 = 120
pick a group of 3 girls: 4C3 = 4
Probability=4/120=1/30

Answer:
24 pounds
Step-by-step explanation:
let Andy's bike be x pounds then Barry's bike is x + 6 ( 6 pounds more )
The total weight of their bikes is 42, hence
x + x + 6 = 42
2x + 6 = 42 ( subtract 6 from both sides of the equation )
2x = 36 ( divide both sides by 2 )
x = 18
Hence Barry's bike weighs x + 6 = 18 + 6 = 24
