Answer:
(6y + 2)² = 4x²
Step-by-step explanation:
Given: x - 1 = 3y
Dividing by 3,
⇒ y = 
Now, to determine 6y, multiply the equation throughout by 6y.
⇒ 6y = 
⇒ 6y = 2(x - 1)
⇒ 6y = 2x - 2
Now, for 6y + 2, add 2 on both sides.
⇒ 6y + 2 = 2x - 2 + 2
⇒ 6y + 2 = 2x
Finally, Squaring both sides, will give us (6y + 2)².
⇒ (6y + 2)² = (2x)²
= 4x² which is the required answer.
Using the formulas
A=πr2
C=2πr
Solving forC
C=2πA
Your answer: 21.27
Answer:
$235.20
Step-by-step explanation:
Calculation for At what price should the manager sell the book shelf
First step is to calculate the price increase using this formula
Price increase=Marks up percentage*Wholesale price
Let plug in the formula
Price increase=60%*$147.00
Price increase=$88.20
Now let calculate the price that the manager should sell the book shelf using this formula
Book shelf Price=Wholesale price+Price increase
Let plug in the formula
Book shelf Price=$147.00+$88.20
Book shelf Price=$235.20
Therefore the price that the manager should sell the book shelf is $235.20
A and C could be the answer
Answer:
-4.4
Step-by-step explanation:
In order to do this, we need to move the variables to one side, and the numerical values to the other.
-20-7x=-2x+2
We can do this by adding 7x to both sides first
-20=5x+2
Now we can subtract 2 from both sides.
-22=5x
Next, we can divide each side by 5.
x=-22/5
Then we simplify the fraction
x=-4.4
