Answer:
w + d = 797
w = d - 53
Because they are equal, we can take whatever is on one side of the = and replace it for what's on the other side.
d - 53 + d = 797
2d = 850
d = 425
Step-by-step explanation:

Therefore you need 4 batches of cupcakes if you want <u>every person to get one cupcake</u>.
- This means you multiply the amount of salt <em>per batch</em> by the number of batches, to get the total amount of salt you need.

Answer:
(a)

(b)

Step-by-step explanation:
Quotient of factorials:
we are given

we can multiply top and bottom term by 21!

we can write as

As a permutation:
we know permutation formula

now, we can compare and find 'n' and 'r'


we can plug back n=25


so, we can write
