X = 52 would be the answer you get.
Explanation you would divide both sides by 0.6 which leaves the x and by dividing 31.2 divided by 0.6 it gives you 52
Answer:
33.75 miles in 45 minutes,
45 miles in an hour
Step-by-step explanation:
45 minutes: 2 1/3= 7/3 ---> 7/3*3=7,
1 3/4= 7/4 ---> 7/4*3=5.25
car travels 5.25 miles for every 7 minutes,
45/7*5.25= 33.75 miles
1 hour (60 minutes):
using that the car travels 5.25 miles for every 7 minutes,
60/7*5.25= 45 miles
Hope that makes sense!
To figure this out, always divide y by x in each table. All of the values have to be equal or the table isn’t proportional.
In this case, the last choice is proportional.
1/3+4/5= 17/15
The commun multipleof 3 and 5 is 15.
1/3×5= 5/15
4/5×3= 12/15
5/12+12/15= 17/12
17/12×7= 119/84
119/84
Hope this helps! :)
\(^ ◇^)/
A = l * w
66 = l * (l - 5)
66 =
-5l
0 =
-5l - 66
l = 11 or 6 check which works.
A = 11 * 6, which fits.
length = 11 miles
width = 5 miles
