Answer:
(8,1)
Step-by-step explanation:
The midpoint is (8,1)
To find the midpoint take the average of the x coordinates and the average of the y coordinates
x= (x1+x2)/2 and y = (y1+y2)/2
x = (-3+19)/2 = 16/2 = 8
y = (-12+14)/2 = 2/2 = 1
You save $15
Work:
75 x 0.20 (20%) = 15
3 + 5 − 1
explination
turn into improper fractions
1*24+16=40
40/24
1*24+21=45
45/24
40/24+45/24=85/24
work out how many times 24 goes into 85 to get back to a mixed number.
24 goes into 85 three times with 13 left over so the answer is
3 and 13/24
