Answer:
x = -(8 - 3 y)/y
Step-by-step explanation:
Solve for x:
y = 8/(3 - x)
y = 8/(3 - x) is equivalent to 8/(3 - x) = y:
8/(3 - x) = y
Take the reciprocal of both sides:
(3 - x)/8 = 1/y
Multiply both sides by 8:
3 - x = 8/y
Subtract 3 from both sides:
-x = (8 - 3 y)/y
Multiply both sides by -1:
Answer: x = -(8 - 3 y)/y
Answer:
Here we have two inequalities.
P is price of the gallon,we have that:
$2.40 ≤ P ≤ $2.65
C is the amount of gallons that Ricardo buys each week.
8,5 ≤ C ≤ 11
Now, with this you can find the maximum and minimum amount that he can spend on a week.
The minimum is when he buys only 8.5 gallons and the price per gallon is $2.40
Cost = 8.5*$2.40 = $20.4
The maximum cost is when he buys 11 gallons, and the price of the gallon is $2.65
Cost = 11*$2.65 = $29.15
So the amount that he spends per week in gas, S, is:
$20.4 ≤ S ≤ $29.15

Answer: See explanation
Step-by-step explanation:
7x - 2(x + 3y) + 3y
= 7x - 2x - 6y + 3y
= 5x - 3y
Will got 5x + 9y because he didn't multiply the values in the bracket by the minus sign outside the bracket. He multiplied the values by +2 rather than -2. This resulted in the wrong answer that he got.
