Answer:
$5
Explanation:
Since Jerry walked the dog from 6:40am to 7:30am, the total minutes that he walked the dog was 50 minutes. Also a note, an hour is 60 minutes.
Since he is paid at a rate of $6 per 60 minutes, we can make a proportion.
660=x50
From here, you have to solve for x. So cross multiply, and then simplify.
60x=50⋅6
60x60=50⋅6/60
60x60=50⋅6/60
x=5⋅6/6
x=5
So the answer is $5.
Answer:
A.
Step-by-step explanation:
We are given the two points (2,7) and (4,-1). In order to determine the linear equation, we need to find the slope and the y-intercept. First, find the slope <em>m.</em> Let (2,7) be x1 and y1, and let (4,-1) be x2 and y2:

Thus, the slope is -4.
Now, to find the y-intercept, we can use the point-slope form. Recall that the point slope form is:

Where (x1, y1) is a coordinate pair and m is the slope.
Use either of the two coordinate pair. I'm going to use (2,7). Substitute them for x1 and y1, respectively:

This is also slope-intercept form. The answer is A.
Answer is: Solve for x by simplifying both sides of the equation, then isolating the variable.
x = 20.2
"d increased by the product of k and f" is d+kf
49/(d+kf)
The final answer is 49/(d+kf)~
