the frist one is 7the second one is 33
Answer:
168 km
Step-by-step explanation:
Let x represent the distance Tyler drives at the slower speed, and let y represent the distance at the higher speed. Using time = distance/speed, we can write equations for the total travel time:
x/42 +y/105 = 2.5
x/28 +y/60 = 4.0 . . . . . 1.5 hours more than the usual 2.5 hours
Multiplying the first equation by 210, we have ...
5x +2y = 525
Multiplying the second equation by 420, we get ...
15x +7y = 1680
Subtracting 3 times the first of these equations from the second, we have ...
(15x +7y) -3(5x +2y) = (1680) -3(525)
y = 105
Putting this into the very first equation, we get ...
x/42 + 105/105 = 2.5
x/42 = 1.5 . . . . . . subtract 1
x = 63 . . . . . . . . .multiply by 42.
The total distance to Tyler's parents' house is ...
63 km + 105 km = 168 km
Answer:
No.
Step-by-step explanation:
Let's find out if 1 bag of soil is enough to fill 1 container.
<u>Given:</u>
2/5 of a bag fills 1/3s of a containter.
With the given, multiplying 2/5 by 2.5 represents one. Multiply 1/3 by 2.5 aswell.
<u>Products:</u>
1, and 2.5/3 or 5/6
1 bag can fill 5/6 of a container.
Therefore, 1 bag can't fill 1 container.
