Answer:
C.
Step-by-step explanation:
This is the correct answer, because ever since the transit system was made, car rides went down and down.
Area = 1/2 * base * height = 1/2 * 5 * 3 3/4 = 9 3/8 or 9.375 in^2
3n + (4n - 2) = 15
is how this equation would be displayed.
Now let's solve for x.
We can distribute a 1 to each term in the parentheses (which doesn't do much) to allow us to combine like terms.
3n + 4n - 2 = 15
Combine like terms.
7n - 2 = 15
Add 2 to both sides.
7n = 17
Divide both sides by 7.
n = 17/7
Let n be the number of books that each student donates...
z * n = 300.....n = 300/z
the number of books Hannah will have left is :
127 - n =
127 - 300/z <==
