Answer:
1.2 hours
Step-by-step explanation:
Recall :
Distance = speed * time
Let the time taken = x
Creating an equation for the question :
Distance of train A + Distance of train B = 192
70 * x + 90 * x = 192
70x + 90x = 192
160x = 192
x = 192 / 160
x = 1.2
It takes 1.2 hours to be 192 miles apart.
Answer:
A
Step-by-step explanation:
If Henry has 20 socks and he split them into a group of 5, he would have 4 socks in each group. To solve this equation you must divide the number of socks by the number of groups. Once you do this, you will get the number of socks in each group.
You are trying to get the x by its self so move the -4 to the other side so that you have 5-2x = 8/-4 then subtract 5 from both sides of the equation -2x = (8/-4) - 5 then once again divid so x = ((8/-4) - 5) / -2
