Answer:
B.
Step-by-step explanation:
the denominator you want is 16 so 4(4) is 16, which makes 3(4) 12 so 12/16. 7/16 is already perfect. 8(2) is 16 therefore 5(2) is 10 which makes 10/16.

Answer:
Gallons: Miles:
0 0
1 23
2 46
3 69
Step-by-step explanation:
First, you would figure out what the unit rate is. To do that, you would divide the 184 miles by the 8 gallons of gas. You get 23 miles per gallon of gas.
Then, to fill out the unit rate table, copy this method:
You know that 0 gallons of gas would lead you nowhere, so you would put a zero in the first row.
In the second row, you use your answer from the first row (0) and add the number of miles per gallon of gas. You would add 0 + 23 and get 23. Put 23 in the second row.
In the third row, you multiply the number of miles per gallon of gas by 2. The answer is 23 x 2 = 46.
Lastly, you multiply 23 x 3 (answer: 69) to fill out the final row.

Answer:
- 170 km on the ground
- 15 km over water
Step-by-step explanation:
Let t represent the amount of time spent over level ground. Then 5.75-t is the time spent over water. The total distance covered is ...
distance = speed · time
40(t) + 10(5.75 -t) = 185
30t + 57.5 = 185
30t = 127.5
t = 4.25
40t = 170
185 -170 = 15
The hovercraft covered 170 km on the ground and 15 km on the water.
