Let the 2 digit number be ab remembering that ab=10a+b
a=b-4...........equation 1
10a+b=3(a+b)+2........... equation 2
take a's value in equation 1 and plug it into equation 2
10(b-4)+b=3(b-4)+3b+2
5b=30
b=6 units digit
a=6-4=2 tens unit
number is 26
Answer:
1.5 miles
Step-by-step explanation:
1.5 miles
Since there are 60 minutes in an hour, the person will walk 60/10 = 6 times as much in 1 hour. If that person can walk 1/4 mile in 10 minutes, she will walk (1/4)*6 = 1.5 miles in 1 hour.
The distance of the hiker of a linear function.
The true statement is <em>(d) The y-intercept is (0, 2), and the 2 represents the number of miles from the car at the start of this time period.</em>
From the graph, we can see that the graph crosses the y-axis at: (0,2)
This means that, the y-intercept is (0,2), and 2 represents the number of miles, he started with.
Hence, the correct statement is (d)
