7) x= men
x+6= women

x + (x+6)= 30
2x + 6= 30
2x= 24
x= 12
x+6= 18

8) x= first integer
x+1= second integer
x+2= third integer

x + (x+1) + (x+2)= 153
3x + 3= 153
3x= 150
x= 50

Second integer
= x+1
= x+50
= 51

9) x= first integer
x+2= second integer
x+4= third integer

x + (x+2) + (x+4)= 54
3x + 6= 54
3x= 48
x= 16

x + (x+2)= 34
16 + 16 + 2= 34
34=34

10) rate= 356 km/hr
distance= 1424 km

Distance= rate * time
D= rt
1424= 356 * t
divide both sides by 356
4 hrs= t
