Answer:
It's A
Step-by-step explanation:
You have to subtract 40 from both sides
Then divide both sides by 8
And then you have your answer.
Answer:
$ 35.96
Step-by-step explanation:
Let x be the cost ( in dollars ) of 4 ounces of the pecans,
So, the ratio of the cost and ounces needed = 
Also, the cost of 1 ounces of pecans is $ 8.99,
Thus, the ratio of the cost and ounces needed = 
Hence, we can write,

Which is the required proportion,
By cross multiplication,
x = 4 × 8.99 = 35.96
Therefore, $ 35.96 is the cost of 4 ounces of the pecans.
Start by distributing the 4:
12-8x=15
Add 8x to both sides of the equation and subtract 15 from both sides:
8x=-3
divide both sides by 8 to get the value of x:
x=-3/8
