Answer:
6 hours
Step-by-step explanation:
Set up a proportion:
15kg/5 hrs = 18kg/x hrs
Cross multiply:
5(18)=15x
90 = 15x
Divide by 15:
90/15 = x
6 = x
I think your answer should be 100 cm...

Answer:
x=-2
Step-by-step explanation:
Given points are (-2,2) and (-2,-3).
Now we need to find equation of the line passing through the given points.
So let's begin by finding slope
which is undefined. That means graph of the line must be vertical as you can see that in given points, x-value is not changing.
Equation of vertical line is given by x=k where k is the fixed value of x-coordinate.
x-coordinate is -2 in given points.
Hence final equation is x=-2.
Answer : B
The dot where the y- axis is 2 and x-axis is 0 would be your y-intercept . For the other 2 dots with planes (3,8) and (2,6) you would do rise over run and connect them. Go down 2 and left 1 so they meet and divide. Once you divide 2 by 1 you get 2 so your equation would be y=2x+2 a.k.a B
Answer: B
