Answer:
5,597 nickels and 4 pennies
Step-by-step explanation:
First, we can take away 4 cents since we know 4 isn't divisible by 5.
Our new number would be 279.80
Then, we divide 279.80 by 0.05 since 0.05 is what a nickel equals>
279.85/0.05 = 5597
Therefore, he would have 5,597 nickels and 4 pennies.

Answer:
The slope is 
Step-by-step explanation:
Take the general equation of a straight line 
Here
is the slope of the line.
So let's get the equation of the line in the question in the same form.

Add
to both sides: 
Add
to both sides: 
Divide by
to get it into the general equation: 
Now compare it to the general equation to find the value of
