Answer:
A = 1/2
Step-by-step explanation:
"A+6=9-5A" is already an equation, and your task here is to solve it for A.
Adding 5A to both sides results in
A + 5A + 6 = 9, or
6A + 6 = 9.
Subtracting 6 from both sides results in
6A = 3.
Thus, A = 3/6, or, in simplest terms, A = 1/2.
the price per pound of the second type of the candy is 2.9 .
<u>Step-by-step explanation:</u>
Here we have , After mixing two types of candies, the price became $3.40 per lb. The quantity of the first type of candy was 5/12 of the quantity of the second type. If the price of the first type of candy is $4.60 per lb,We need to find what is the price per pound of the second type of the candy . Let's find out:
The quantity of the first type of candy was 5/12 of the quantity of the second type i.e. Quantity of candy A = 5x quantity of candy B = 12x
We need to calculate the weighted average of the price of candies.
price of mixture = quantity of A (price of A ) + quantity of B (price of B)
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Therefor , the price per pound of the second type of the candy is 2.9 .
