45/100 is 4,500%
2/5 is 40%
18/40 is 45%
15/25 is 60%
The correct answer is A Marie does not know how many cherries she has to share. She knows she is sharing her cherries equally with 3 friends
= x1 + x2/2 , y1 + y2/2
= 7+-1/2 , 1+(-1)/2
Midpoint = (3,0)
The slope of any line can be calculated using the following rule:
slope = (y2-y1) / (x2-x1)
The given points are (-14,-10) and (7,5), therefore:
y2 = 5
y1 = -10
x2 = 7
x1 = -14
Substitute with these values to get the value of the slope as follows:
slope = (5--10) / (7--14) = 5/7
