So the man can wash lies Down
Answer:
1,000
Step-by-step explanation:
20
20×10×5=1,000
3/4=0.75 or 75%
1/2=0.5 or 50%
So, 3/4 is bigger.
If y varies directly with x, means that they can be modeled by a linear equation, lets choose a line with 0 y intercept, that is:
y = mx + b
y = mx
where m is the slope of the line, now we plug in the data we have:
y = mx
20/3 = m(30)
solving for m:
m = (20/3)(1/30)
m = 20/90
m = 2/9
so the line equation, or function modeling the y and x relationship is:
y = (2/9)x
