Answer:
54
Step-by-step explanation:
54
I believe your answer is C. But I’m not completely sure!
50 is the value cause 20 is 40 of the percent, 20+20 is 40 now you made it into 80%.20% is remaining so add 10.
3x+75=180( cause supplementary angles)
-75 -75
3x=105
3x/3= 105/3
x=35
Examples :
2/x < 4 ....multiply both sides by x, cancelling it on the left side
2 < 4x ...now divide by 4
2/4 < x
1/2 < x
5/x + 7 > = 12
5/x > = 12 - 7
5/x > = 5 ....multiply by x, cancelling it on the left
5 > = 5x...divide by 5
5/5 > = x
1 > = x
