168
So you take the 144 divide 12(the dozen) so we could find how much 1 cost, it was 12. You added 2 more books so we add(12x2)+(144). That equals to 168
Hope this helps!
Answer:
(3, 2)
Step-by-step explanation:
This is a system of equations so I'll solve it using the 'Addition method'.
3x - 2y = 5 | x + 2y = 7
Add the two equations together to get:
4x = 12
x = 3
Then we solve for y using the 2nd expression because it's easier.
3 + 2y = 7
2y = 4
y = 2
To find the slope, we need two points that are located on this line.
The following two points are on this line: (0,-4) and (3,1).
Let m = slope
m = (1 -(-4))/(3-0)
m = (1 + 4)/3
m = 5/3
The slope is 5/3.
The answer is every long.
