Aljan and Bella are both driving from Cleveland to Chicago. Aljan leaves at

Natalija [7]

Answer:

Bella will pass Ajjan after 4h and they will have travelled 260 miles.

Step-by-step explanation:

In order to calculate the number of hours, "x", that it'll take for Bella to pass Aljan, we need to find the value of "x" that makes both equations equal. Therefore,

$60*x + 20 = 65*x\\65*x - 60*x = 20\\5*x = 20\\x = \frac{20}{5} = 4$

In order to calculate the distance they traveled, we must use this value for "x" in any of the equations, as done below:

$y = 65*4\\y = 260$

Bella will pass Ajjan after 4h and they will have travelled 260 miles.

A first number plus twice a second number is 24. twice the first number plus the second totals 21. find the numbers.

Ulleksa [173]

We do like the following:
Set the first number is a and the second is b.
We have two equations: a+2xb=24, 2xa+b=21
And we have 2xa+4xb=48 or 2xa=48-4xb
So: 48-4xb+b=21 or -3xb=21-48=-27 and we got b=-27:(-3)=9 and a= 6
a=6 and b=9
