Answer:
C
Step-by-step explanation:
-0.2(x-20)=44-x
Divide both sides by -0.2:
x-20=-220+5x
Subtract x from both sides:
-20=-220+4x
Add 220 to both sides:
200=4x
x=50, or answer choice C. Hope this helps!
I dont have time to do all of these right now my apolgies but Ill explain how to do it.
The 3 angles of a triangle add up to 180.
So let me show you how to do 1.
.
.
.
1. 58 degrees
92, 30, ?
If we add together the first two angles,
92+30= 122
Knowing the total addition of all three angles would ne 180, we can subtract 122 from it to get the third angle.
180-122= 58
So we now know the last angle is 58 degrees because
92+30+58=180
Most teachers say that they do it to make sure the kids dont't forget what ws tought that day or to review
