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
Answer:
The slope of the equation is -1, so the slope for the parallel line will also be -1.
Step-by-step explanation:
Answer:
x=2
Step-by-step explanation:
12X2=24+3=27
Answer:
Step-by-step explanation:
first add mx on both sides
y = p + mx
Subtract p on both sides
y - p = mx
divide m on both sides
= x
Answer:
5a + 2b
Step-by-step explanation:
9a + 3b -4a -b
9a - 4a + 3b - b
5a + 2b
