Answer:
210 books
Step-by-step explanation:
Hello
I think I can help you with this
Step 1
if one box is 7.5% of the total shipment, how many box is the total shipment
1 box =7.5%
x?box=100%
using a rule of three

Now, isolating x

13.34 boxes is the total
Step 2
find the total of books
we will need 14 boxes, because it does not exist 0.34 box
so, the total of books=
number of boxes*number of books included in each box
=14 boxes*15 books
=210 books
Have a great day
Area = length x width
x² + 12x = l * x
A. First, you factor x from x² + 12x

area = x (x+12)
area = (x+12) * x
Length = x + 12
B.If
x = 10,l = x + 12 = 10 +12 = 22
length = 22
and
Area = x² + 12x = 10² + 12(10) = 100 + 120 = 220
area = 220 Hope this helps :)
Answer:
15.38461538461538
Step-by-step explanation:
The given details are illustrations of addition and subtractions of fractions. The scuba driver is at an elevation of
ft below the sea level.
Given that:
--- the first dive
---- the additional dive
From the question, we understand that the diver starts at the sea level.
This is represented with 0ft.
So, the diver's elevation (d) is calculated as follows:
--- we use subtraction because the diver is below the sea level
So, we have:


Convert fractions

Take LCM


Reduce fraction

The above value means that the diver's elevation is at
ft below the sea level.
