It would be 12% of 50
50 * 12/100 = 600/100 = 6
so, 6 cars are red
First you would subtract x from both sides to move all the x's to one side
Then you would add 4 to both side to move all the non x's to one side
Lastly divide by negative 15 to have x by itself
9/-15 =-.6
So x as has root at x=-0.6
Answer:
x=33
Step-by-step explanation:
x+(3x+48)=180
combine like terms
4x+48=180
subtract 48 from 180
4x=132
then you divide both sides by 4
x=33.
check your work (plug it in)
33+((33x3)+48)=180
33x3=99
99+48=147
then you add 33 from the other x
147+33=180
