Answer:
h < 4
Step-by-step explanation:
Simplify both sides
-8h + 16 > -3h - 4
Add 3h to both sides
-5h + 16 > -4
Subtract 16 from both sides
-5h > -20
Divide both sides by -5
-20 divided by -5 = 4
Since you divided by a negative number, you change the inequality sign to < instead of >
Answer:
B
Step-by-step explanation:
Firstly, let’s say they are to fill a total of x liters, rate for big hose would be x/20 while for small hose it would be x/30.
Now if they are to work combined, total time would be
x/20 + x/30 = 5x/60 = x/12
Hence, it will take them 12 minutes
The correct answer is "D".
q+r=p
Because the missing angle would equal 180-q-r, it would be the same as p. The one angle (the unmarked) is supplementary to the missing angle. (180 degrees)
I hope this helps!

7+2h= g. Add 2h to other side to make g alone
3(7+2h) + 3h = 10 Substitute
21+6h +3h= 10. Distribute
9h= -11
H= -11/9
