Answer:
Find the slope of the line that passes through the points shown in the table.
The slope of the line that passes through the points in the table is
.
Step-by-step explanation:
If we count 28 minutes from 3:32PM, we arrive at 4:00PM.
From there, we count two more hours and we arrive at 6:00PM.
So, there are 2 hours and 28 minutes until Emma's lesson.
Since one hour is 60 minutes, two hours are 120 minutes.
So, the total number of minutes is 120+28 = 148
It will take him 3 hours driving at 65 miles an hour
Answer:
Step-by-step explanation:
Let the number = x
So we are trying to work out what number must be subtract from the numerator and denominator of 5/3 to equal 5/7.
You can write this as:
Then you want to get rid of the fractions so multiply both sides by 3-x
Then multiply both sides by 7
Multiply it out.
35 - 7x = 15 - 5x
Add 7x to both sides:
35 = 15 - 5x + 7x
35 = 15 + 2x
Subtract 15 from both sides
35 - 15 = 2x
20 = 2x
To find x, divide both sides by 2.
x = 10.
