Total slices=4*6=24. Take away 3 slices leaving 21=18+3=3 pizzas and ½ a pizza, 3½.
Its 37 and yea its an easy question lol
Mean Absolute Deviation I'm pretty sure. Hope this helped, have a great day! :D
She practices 5 hours a day.
120/4 = 30 hours per week.
30/6 = 5 hours per day.
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
