Answer:
(-1, 3)
Step-by-step explanation:
The midpoint is the average of the end points.
M = (H +K)/2
M = ((-4, 10) +(2, -4))/2 = (-4+2, 10-4)/2 = (-2, 6)/2
M = (-1, 3)
The coordinates of the midpoint are (-1, 3).
Answer
Find out the what was his total cost .
To prove
As given
A tent was marked up 150% from an original cost of $52.
Last Friday, Ethan bought the tent and paid an additional 10% in sales tax.
Than the equation becomes
150 % is written in the decimal form .

= 1.5
10 % is written in the decimal form .

= 0.1
cost of the tent when 150% marked up from origianl price = 1.5× 52
= $ 78
cost of the tent = origianl cost + 150% marked up from origianl price
= $52 + $78
= $ 130
Sales price on the tent = $130 × 0.1
= 13
Total cost of the tent = $130 + $13
= $143
Therefore the cost of the tent is $143.
Answer:
7A. x = 6
7B. m∠ABC = 135°
Step-by-step explanation:
7A. I forget what the rule is called specifically, but the opposite angle is always congruent. So, you simply end up solving for x when you set the equation to equal 45.
7B. Use the supplementary rule, which basically states that two angles on a flat plane, when adjacent, equal 180°. So, 180 - 45 = 135.
God, my terminology is awful, but that's besides the point.
Answer:
