The machine was operated for 4.5 hours
A machine uses gasoline at a rate of 1/5 gallon per hour
The number of hours it will take the machine to use 9/10 gallon can be calculated as follows
1/5 = 1
9/10= x
cross multiply
1/5x= 9/10
0.2x= 0.9
x= 0.9/0.2
x= 4.5
Hence the machine was operated for 4.5 hours

Answer:
This question is not as hard as it seems.
Let the first number = x.
The other number will be x - 16.
The sum of both the number is 52.
So, x+x-16 = 52
Which would simplify to 2x -16 = 52.
When I add 16 to both sides, it would give me 2x = 68.
Then, divide both sides by 2.
This leaves us with x = 34.
Since we have x, now x-16 would be 34-16 = 18.
The two numbers are 34 and 18, this answer is correct because both of them add up to give me 52.

Answer:
hm the 8 per hour seems more accurate because if you multiply or divide 8 could almost get you to 120
Step-by-step explanation:
So the image consists of 1 rectangle and half a circle.
Rectangle - 12*19 = 228
Half a circle -
In the end there are 2 rectangles (2*228 = 456) and 1 full circle (18*2 = 36), which makes the shaded area 456 ft and 36
