You just needed to do is 25% and then times it by 21 you should get 5.25
Step-by-step explanation:
slope = 2-4/2-1 = -2
y - 2 = -2(x - 2)
y-2 = -2x +4
y = -2x + 6
The 81 balls need to be split into some number of boxes. To figure out how many boxes, we can divide the 81 balls by the 7 ball capacity of a single box.
81/7 = 11.571
This means that we will need 11 full boxes, but there will be a remainder of balls which did not fit. Since we can't have a fraction of a box, we need to round up to 12 boxes to hold all 81 balls.
The answer is 12 boxes.
Devide 120/83=1.45 is rounded to nearest hundreth
