Answer:
Step-by-step explanation:
If you want the mid point for these questions then for the 1st
1. add -6 and -2 which is -8 then divide by 2 which is -4, then add -1 and -3 which is -4 and then divide by 2 which is -2. so the mid point is (-4,-2)
2. its the same as above first add -4 and 2 which is -2 then divide by 2 which is -1, then add -5 and 3 which is -2 and divide by 2 which is -1. the point is (-1,-1)
3. -3+3=0 dived by 2 which is 0, -1+5=4 divide by 2 which is 2
point is (0,2)
4. -3+4=1 divide by 2 which is 1/2 =0.5, -2+7=5 then divide by 2 which is 5/2=2.5. point is (0.5,2.5)
Answer: 8x - 32
Work:
Simplify using the distributive property of multiplication.
8(x) = 8x
8(-4) = -32
Simplified expression: 8x - 32
If you use a calculator its easy
16.72 - 1.24 = 15.48
15.48 divided by 12 is 1.29
for sales tax 1.24 divided by 12 is .10
so for each one She spent $1.39

Complete question
(A zip line starts on a platform that is 40 meters above the ground. The anchor for the zip line is 198 horizontal meters from the base of the platform.
How long is the zip line? See attached diagram for illustration)
Using pythagoras theory
Y = 40
Z = 198
X =?
X² = y² + z²
X² = 40² + 198²
X² = 40804
X = 202m
The zip line is 202m
