Using (6C3 x 9C4)/ 15C7 to find probability of 3 out of 6 youtube and 4 out of 6 online divided by 7 out of 15 total
Answer:
Step-by-step explanation:
(a) Number of necklaces
3⁵/₈ = 3.625
(b) Value of gold in each necklace
There are 3.625 oz of 14K gold in each necklace. Pure gold is 24K.
Pure 24K gold is worth $1050/oz.
Let's solve for b.
2b−7x=3(b−3)
Step 1: Add -3b to both sides.
2b−7x+−3b=3b−9+−3b
−b−7x=−9
Step 2: Add 7x to both sides.
−b−7x+7x=−9+7x
−b=7x−9
Step 3: Divide both sides by -1.
−b
−1
=
7x−9
−1
b=−7x+9
Answer:
b=−7x+9
What Ratio table??? There is no pic
Answer:
25
Step-by-step explanation:
First we add 1 to both sides :
√x = 5
Now we square both sides :
x = 5²
x = 25
To check this answer we substitute our answer back into the original equation:
√25 - 1 = 4
5 - 1 = 4
4 = 4
