We can have two d = rt equations.
d = 40 t
d = 50 (9 - t)
We know the distance is the same, so we can just set the equations equal to each now.
40 t = 50 (9 - t)
40 t = 450 - 50 t
90 t = 450
t = 5
So, Terrell took 5 hours going 40 mph, and 4 hours going 50 mph. 5 * 40 gives us 200 miles one way.
Answer:
The range in shelter A is 22, and the range in shelter B is 18.
Step-by-step explanation:
Okay so basically, the range is the difference between the smallest number and the greatest number.
The smallest weight for shelter a is 8. The largest weight is 30.
30-8= 22.
Same thing for the other shelter. The smallest weight is 10, and the largest weight is 28. 28-10= 18.
represents the system of equations
Hope it helps
3x-2y=7
3x=7
x=7/3
-2y=7
y=-7/2
so...(7/3,-7/2)
310=62% of x
let x b the total number of pages
x=500 so total number of pages are 500.
and rest has no picture=500-310=190
