Answer:
x < -3/4 OR x>16/5
Step-by-step explanation:
5x – 4 > 12 OR 12x+5 < -4
Solve the parts separately and then put back together
5x – 4 > 12
Add 4 to each side
5x-4+4>12+4
5x >16
Divide each side by 5
5x/5>16/5
x > 16/5
12x+5 < -4
Subtract 5 from each side
12x+5-5<-4-5
12x<-9
Divide each side by 12
12x<-9/12
x <-3/4
Put back together
x < -3/4 OR x>16/5
1+1 = 2 that is the answer
Answer:
400
Step-by-step explanation:
0.30 * x = 240
x = 240/0.30 = 800
0.50 * 800 = 400
4(4x)+2(x)=72
16x+2x=72
18x=72
x=4
