Answer:
W=16
Step-by-step explanation:
Add 17 to both sides
81-1= 80
80 / 2 = 40
D = 40
So:
40(2) = 81 - 1



which means either

or

. The equation has no solution, since

is always bounded between -1 and 1. The second has one solution at

, and any number of complete revolutions will also satisfy this equation, so in general the solution would be

where

is any integer.
So you could choose

and

.
32b+12
32 and 12 is both divisible by 4 so divide them by 4 and the answers in parentheses
4(8b+3)
The <em><u>correct answers</u></em> are:
7 mugs on each shelf; and 7 shelves for blue and 8 shelves for red.
Explanation:
To find the number of mugs that will fit on each shelf, we find the GCF (greatest common factor) of 49 and 56. To do this, we find the prime factorization of each:
49 = 7(7)
56 = 7(8)
8 = 2(4)
4 = 2(2)
56 = 2(2)(2)(7)
The only common factor is 7, so this is the GCF. This means that she needs to put 7 mugs on each shelf.
Since there are 49 blue mugs, she needs 49/7 = 7 shelves for them.
Since there are 56 red mugs, she needs 56/7 = 8 shelves for them.
