Well, you can't really determine the price of 1 book, but you can find out the average cost.
280 - 16 = 8x (x = cost of 1 book)
264 = 8x
264/8 = 8x/8
33 = x
So the average cost of one book is 33$( A little expensive if I do say so myself)
Hope this helped!
A; X = 60, Y = 150. I found the answers by dividing 300 into 2, and 6,750 into 45.
B; It's better to do per minute, since there's no need to divide back to find the original time.
Answer:
y<(x-2)^2
Step-by-step explanation:
To graph this inequality, we first identify the function.
This is a quadratic function y=x^2
The function is translated horizontally to the right two. (x-2)^2
It is also a dotted line, <.
Answer: p= 25n/7 358
n will be the total number of students on the field trip
g could represent the number of groups
p will represent the number of pencils
For this situation with 100 students, John will need 358 pencils. for 14 2/7 groups.
To be safe, since he has a partial group, he should round up to 15 groups and get 375 pencils. Especially if the pencils only come in boxes of 25, and he can't buy a partial box.
Step-by-step explanation:
25g = p
g =n/7
Combine these to get the ratio
g becomes unnecessary
p= 25n/7
the exact calculation for g was 100/7 = 14.28571
The exact calculation for p = 100/7 × 25 = 357.142857
But you can't buy partial pencils!
