Answer:
1
Step-by-step explanation:
54
a rule I follow:
same signs positive,
different signs negative.
-9 * -3 = 27
27 + 27 = 54
In this way we can list the equation out:
3s + 4y - 1 = 6s
4y - 1 = 6s - 3s
3s = 4y - 1
s = (4y - 1) / 3
since we don't know the exact number of y, so we can only solve s in terms of y.
Answer:
$4.75 per 18oz
Step-by-step explanation:
To calculate the better deal we need to find the price per oz.
To find the price per oz for $4.75 per 18oz, we divide by 18.
$4.75/18 = $0.26 per oz
Now lets find the price per oz for $11.29 per 40oz
To find the price per oz for $11.29 per 40oz, we divide by 40.
$11.29/40 = $0.28
So the better deal is the 1st deal of $4.75 per 18oz.
