8-6z=26
8-8-6z=26-8
-6z=18
divide by -6 for -6z and 18
-6z/-6=18/-6
z=-3
Check answer by using substitution method
8-6(-3)=26
8+18= 26
26=26
Answer is z=-3
Answer:
no
Step-by-step explanation:
y =x
Substitute the point into the equation
5 =0
This is not true so the point is not a solution
We need to find the lowest common multiple...
multiples of 14 are : 14,28,42,56,70,84,98,112,126,140,154
multiples of 20 are : 20,40,60,80,100,120,140
so the lowest common multiple is 140....so thats 140 minutes....= 2 hrs 20 minutes....from 8:00 = 10:20
so they will both leave at the same time of 10:20 a.m. <==
It should be
72:24 = 15:5
