Answer:
Step-by-step explanation:
25.
x + 2x -75 = 90
3x = 90+75
3x = 165
x = 55
Measure of A = 55
Measure of B = 2(55) - 75 = 110 - 75 = 35
28.
2x+10-x+55 = 90
x = 90-65
x = 25
measure of A = 2(25) +10 = 60
measure of B = -25+55 = 30
31.
2x+3+3x - 223 = 180
5x -220 = 180
5x = 400
x = 80
measure of A = 163
measure of B = 17
32.
-4x+40+x+50 = 180
-3x +90 = 180
-3x = 90
x= -30
measure of A = -4(-30) +40 = 160
measure of B = -30+50 = 20
Where's the graph?? I can't answer if there's no graph. lol xD
Answer:
x = -4

Answer:
Where are the circles?
Step-by-step explanation:
<u>Answer:</u>
The answer is A
<u>Step-by-step explanation:</u>
The answer needs to be in slope-intercept form or y=mx+b because the amount of carpet being cleaned every minute is a constant decrease of 9 square feet.
So our b value (or how much carpet cleaned at 0 minutes) is 220
And our m value (or slope or how much carpet is being cleaned every minute) is 9
So if we plug the variables with the tangible numbers we get A(t) = -9x+220 or A(t) = 220-9x.
