Answer:
see below
Step-by-step explanation:
2x+8y=12 3x-8y=11
If we have to solve by substitution, Take the first equation and divide by 2
2x/2 + 8y/2 =12/2
x+4y = 6
Then subtract 4y from each side
x = 6 -4y
Then substitute this into the second equation
This is best solved by elimination
2x+8y=12
3x-8y=11
----------------
5x = 36
x = 36/5
The answer for this is n(3+2)
Given:
grapes = 2 1/2 pounds
apples = 1 1/4 times as many pounds as grapes.
For easier computation, let us convert these fractions into numbers with decimal places.
2 1/2 pounds = 2.50 pounds
1 1/4 times = 1.25
Apples = 2.50 pounds * 1.25 = 3.125 pounds of apples.
Or we still use fractions. We need to convert the mixed fractions into improper fractions.
2 1/2 = 5/2
1 1/4 = 5/4
5/2 * 5/4 = 5*5 / 2*4 = 25/8 is simplified to 3 1/8 pounds
The formula for N choose K is given as:
C(n, k)= ![\frac{n!}{[k!(n-k)!] }](https://tex.z-dn.net/?f=%20%5Cfrac%7Bn%21%7D%7B%5Bk%21%28n-k%29%21%5D%20%20%7D)
Where,
n is the total numbers.
k is the number of the selected item.
Options C is correct.
