D = distance from finish line
D= 5 - 1/3x
Distance from the finish line is equal to the distance of the start line from the finish line, minus one third of a km times the number of minutes hes been running.
using given variables; D= 5 - 1/3*3
D=5-3/3
D=5-1
D=4
None of the above. The first two are slope-intercept, whereas the third one isn't a form.
Answer:
Hello!
Let's simply divide our two numbers to find how many carriages we need.
22/4=5.5
The thing is, we cannot have 5.5 carriages. We can just have an extra carriage with only 2 people. This gives us 6 carriages.
Therefore, our answer is 6.
I hope this helps!
1 foot = 12 inches
12 * 5 = 60 and 8 * 12 = 96
Therefore, 60 inches is a shorter length than 8 feet.
Let

be the amount of time it takes to perform an arm routine and

be the amount of time it takes to perform an abdominal routine. We see:


Subtracting the second equation from the first gives

. Substituting gives

, so

and

.
Thus, an arm routine takes ten minutes and an abdominal routine takes thirty minutes.
