A+6=9-5a what's the equation of this problem

ankoles [38]

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.

Fynjy0 [20]

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)

⇒ $3.4(12x+5x)=12x(Price)+5x(4.6)$
