I'm thinking its a im not sure though since i just finished getting out of that unit
Answer:
The train appears to go the same distance each minute
9mins
The cost for each person appears to be the same
Step-by-step explanation:
So for the first qu you basically want to find the distance the train travels each minute, so for
3mins : 9km
therefore
1min : 3km
basically divide 9 by 3
then the train travels 27km, how long does it take?
if 3km = 1min
then 27/3 = 9
so it takes the train 9 minutes
Then for the second qu you'll do the same thing
2ppl : $16
so one person : 16/2
so 1 person costs $8
so for 8 ppl you multiply 8 by 10
8ppl : $80
hope this helps:))))
well i cannot help u graph but u need to get them in y=mx+b form first
2x+y=4
y=-2x+4
2y-4x=6
2y=4x+6
y=2x+3
now that the problems are in y=mx+b form, u can graph them. the "b" is your y-intercept. you need to graph this first so what ever ur be is, put a point there on the y axis. then use your slope to plant your line. slope is rise/run. so for the top problem start at your y intercept and go down 2 and to the right 1. and for the bottem problem, start at your y intercept then go up 2 and to the right 1
HOPE THIS HELPED!
Answer:
17x+4=123(alternate angle)
17x=123-4
17x=119
x=7
We are simplifying this so they are easier to add in your head.
87+33 is easier math to do in your head
so our new estimated number would be 120
