Answer:
6 dollars
Step-by-step explanation:
40-10=30
30/5= 6
Maybe it was (7-2x)/-4+2<-x then times 4 both sides
<span>
</span>
-7+2x+8<-4x
<span>
</span>
2x+1<-4x
<span>
</span>
6x+1<0
<span>
</span>
6x<-1
<span>
</span>
x<-1/6
<span>
</span>
there we go
The solution is 25% acid, which means 2.5 liters acid (10 x .25).
<span>you need that 2.5 liters to be 10%, or 1/10th the total. </span>
<span>the total would have to be 25 liters (2.5 x 10) so when you add to 10 to get 25 you get </span><span>15 liters. Hope I helped!</span>
