<h3>
Answer: 100 degrees</h3>
===============================================================
Explanation:
The two angles that involve x are alternate interior angles.
Due to the parallel lines, the alternate interior angles are equal.
We'll use this to solve for x
-7x-18 = -9x-46
-7x+9x = -46+18
2x = -28
x = -28/2
x = -14
Let's check the answer by evaluating each expression as shown below
- -7x-18 = -7*(-14)-18 = 80
- -9x-46 = -9*(-14)-46 = 80
Both angles are 80 degrees each, so it confirms we have the correct x value.
-----------------------
We have one last step. We found the -9x-46 angle to be 80 degrees. Angle 4 is adjacent to this and supplementary.
So we subtract from 180 to get the answer
180-80 = 100
Answer:

Answer:
Hi,
Step-by-step explanation:
So it says the first six months average is 75mm. Total÷Amount =Average so Average x Amount = Total The first six months is 75 so 75x6= 470. The last six months is 15 so 15x6=90. In total, 470+90=560. We need to find the new average so we do 560÷(6+6)= 46.666666… so we round it to 46.67.
I. hope you find this helpful.
Answer:
(3,1)
Step-by-step explanation:
(x,y) (-4,2)
so -4 +2 = - 2 ; -2 +5 = 3
and for y: 2 - 5 = - 3 ; - 3 + 4 = 1
(3,1)
