If the ratio is 3:5, then for every 3 boys there are 5 girls, so you multiply 3 and 5 by 24 and you get your answer.
you know that y=mx +c then in the place of m is 3 then answe is also three.
Answer:
k = 2.5
Step-by-step explanation:
Compare y = 2.5x to y = kx (which is the equation for direct proportion):
k = 2.5 is the const. of prop.
Answer:
y=-2x+16
Step-by-step explanation:
since you are given the slope, you can plug it into the equation y=mx+b where m= slope and b= y intercept
you now have y=-2x+b
to find b, you have to plug in the coordinate you are given into the equation
6=-2(5)+b and solve for b
6=-10+b
b=16
since you now have both the slope & y intercept, you can plug them both back into the original equation, y=mx+b and you get
y=-2x+16

2300 I think was the answer if my calculations are correct
