The round trip was 8 miles ( 4 + 4 = 8)
The total time for the trip is 3/10 + 1/2
Rewrite 1/2 as 5/10
Now add 3/10 + 5/10 = 8/10 = 4/5 hour for the 8 mile trip.
Now to find miles per hour, divide total miles by total time:
8 miles / 4/5 hour
When you divide by a fraction flip the fraction over and multiply:
8 x 5/4 = 40/4 = 10
The average rate was 10 miles per hour.
Step-by-step explanation:
9x - 3y = 18
Solve for y:
1. 3y= 9x + 18
2. y= 3x + 6 (This is the equation you will graph)
To graph:
Make a table for y = 3x +6.
If x =0, y=6
If x =1, y=9
If x =-1, y=3
You could get as many points as you like, however you need at least TWO, to be able to draw the line.
Answer:
Peter withdrew $47.27 and deposited $598, decreasing his balance by $550.73.
Step-by-step explanation:
He took $42.27 from his bank account, and then put in $598, which made the final total $550.73
5y+2x-3=0
5y=-2x+3
y=-2/5 x+3
Sope intercept of the line is y=-2/5 x+ 3/5.
The intercept is 3/5.
Check: x=0 when y=3/5
5y+2x-3=0
5(3/5)+2x-3
3+2x-3=0
2x=0
x=0
Correct
The answer is 3/5.
Answer: C
Step-by-step explanation:
The x times 4 equals the y in each column.
