Answer:
The number is infinity
Step-by-step explanation:
Let the unknown number be x
if the number increased by three, then we have;
x + 3
Also quadrupling that number increased by five all divided by four is expressed as;
(4x+5)/4
Equating bith expressions and calculating x;
x+3 = (4x+5)/4
cross multiply;
4(x+3) = 4x + 5
4x+12 = 4x + 5
4x-4x = 5 - 12
0x = -7
x = -7/0
x = ∞
Hence the number is infinity

Answer:
A.
Step-by-step explanation:
d = rt
If t is the time taken by the train, then the truck takes t+2 hours.
For the truck:
d = 45(t + 2)
For the train:
d = 60t
Total distance travelled by both:
= 2d
= 60t + 45(t + 2)
= 60t + 45t + 90
= 105t + 90 where t is the time taken by the train.

Answer:
20.5
Step-by-step explanation:
The median is the middle number when the numbers go from smallest to largest
18,18,20,21,24,26
Since there is an even number, we take the two middle numbers and add them together and divide by 2
20+21
---------
2
20.5
