Answer:
He bought 17 books.
Step-by-step explanation:
Given that:
Total money spent = $89
Cost of each book = $5
Shipping price = $4
We have to find, Total number of books
So if the number of books be represented by b, the equation will become:
Cost of one book * total number of books + shipping price = total money
Putting values we get:
5*b + 4 = $89
By simplifying:
5*b = 89 - 4
5*b = 85
Dividing both sides by 5 we get:
b = 17
So the total number of books bought is 17.

Answer:
128°
Explanation:
1 = 4 because of vertical angles are the same
4 = 5 because of alternate interior angles are the same
5 = 8 vertical angles
8 = 9 alternate interior angles
9 = 12 vertical angles
180° = 12 + 11
11 = 180° - 52°
angle 11 = 128°

Answer:
6 · x = 42 and x = 7
Step-by-step explanation:
Varies jointly means that y is related to the product of x and z:
.. y = k*x*z
.. 64 = k*8*4
.. k = 64/32 = 2
Then for your new numbers,
.. y = 2*7*6
.. y = 84
