5(x-3)-x =
Multiply Everything In The Parentheses By 5
5x-15-x
Answer:
a
Step-by-step explanation:
6^2+8^2=100
sqrt of 100 = 10
The least amount is 2 packs.
i know this becaus first i make a lcm chart which looks like this :
8: 8,16,24,32
12: 12,24
i then see that the lcm is 24 and 12+12 is 24 meaning that i will have to buy 2 packs of large plates.
We let x as the cost of one ounce of Sumatra and y as the cost of one ounce of Celebes Kalossi. For mixture 1, we have 12x + 4y = 32 and for mixture b, we have 4x + 12y = 40
First, Multiply eq. 1 by 4
4(12x + 4y = 32)4 ⇒ 36x + 12y = 96
We now have
(36x + 12y = 96) – (4x + 12y = 40)
<span>X = 1.75 ⇒ cost of one ounce of Sumatra
</span>
Substitute x to either equation to get the value of y
12(1.75) + 4y = 324
y = 32-21
4y = 11
Y = 2.75 ⇒ cost of one ounce of Celebes Kalossi
