What do i do please help!

Mathematics
1 answer:
Art [367]3 years ago
8 0

Answer:

Step-by-step explanation:

this is confusing b/c they are asking about two trains traveling at differnt speeds, but.. if you put the speeds together and make one train... imaginary.. ofc... traveling at the speed of both trains combined... when will it be 50 miles from the station?

maybe you can solve that?   I'll solve it below.. but.. if you can.. try it now, on your own

below is my answer... don't look until you have solved yours :P

80+70= 150kph

when will this have traveled 50Km?

you may be able to see that it will take 1/3 of an hour to travel 50 km

so 60 minutes times 1/3 = 20 minutes  :)

Can anyone help me do this equation?
lilavasa [31]

The solution to the given equation is x > 5.3

<h3>Solving linear inequality</h3>

Inequality are expression that are separated by an equal sign.

Given the inequality;

16(1/4 x - 1/2) > 24-  2x

Expand

4x - 8 > 24 -2x

Collect like terms

4x + 2x > 24 + 8

6x > 32

x > 32/6

x > 5.3

Hence the solution to the given equation is x > 5.3
