Answer:
1 hour and 45 minutes
and 1 hour
Step-by-step explanation:
x= run
y= walk
5x+2.5y = distance
5x+2.5(1.5)=12.5
solve for x
5x=8.75
x=1.75
1.75 in hours is 1 hour and (60*.75)=45
1 hour and 45 minutes
" If the marathon race participant ran for 2 hours, how many hours did the participant walk?"
We use the same equation
5x+2.5y=distance
we'll assume that they till walked 12.5 miles
which means that
5(2)+2.5y=12.5
solve for y
2.5=2.5y
y=1
1 hour
Answer:
B
Step-by-step explanation:
The 1st and 3rd ones are growth. The 2nd and 4th are decay. You can figure this out by looking inside the ( ). If the number is greater than one, it is growth. If the number is less than one, it is decay.
Hope this helped :)
Answer:
slope: 8.75 y intercept: 0
Step-by-step explanation:
Im not certain, but i think the equation would be y = 8.75x. I dont think there is a y intercept because she doesnt have any money to start with
