150, I believe
"if 40% of a number is 60" (40/100) * x = 60 (.4) x = 60 [reduce or just write it this way] x = 60(.4) [multiply both sides by .40]
Before the fraction: -1/2, i have a negative sign
use y=mx+b
3=-1/2(2)+b
3+1=-1+b+1
4=b
check your work
0=-1/2x+4
0+4=-1/2x
(4)÷(-1/2)=(-1/2x)÷(-1/2)
-2=x
another pair is (-2,0) use this to figure out the other points, and/or the points you have in the multiple choice.
Answer:4 times x
4(x)
Step-by-step explanation:
4 times as many songs on Lou's music player
Lou's music player is x
P/90 = 4/18
18P = 90*4 [cross-multiplication]
P = 360/18
P = 20
So, answer is P equals to 20
