Answer:
Step-by-step explanation:
Given equation is . We require x in terms of c.
Dividing both sides with 3 we get
Add 7 on both sides we get
Dividing both sides with c we get
X = 33
X can Be mirrored vertically and then is supplementary to x
Answer:
1.683 minutes = 0.02085 hours
Step-by-step explanation:
1 hour is equivalent to 60 minutes
60 minutes = 1 hour
Now, to give the answer as a mixed number : Convert the answer obtained in decimal into fraction
But as the numerator is less than the denominator so the answer cannot be expressed as a mixed number.
Answer:
x=6+2√3 or x=6−2√3
Step-by-step explanation:
Let's solve your equation step-by-step by using completing the square.
5x^2−57x=3x−120
Step 1: Subtract 3x from both sides.
5x^2−57x−3x=3x−120−3x
5x^2−60x=−120
Step 2: Since the coefficient of 5x^2 is 5, divide both sides by 5.
5x2−60x/5
=
−120
/5
x2−12x=−24
Step 3: The coefficient of -12x is -12. Let b=-12.
Then we need to add (b/2)^2=36 to both sides to complete the square.
Add 36 to both sides.
x2−12x+36=−24+36
x2−12x+36=12
Step 4: Factor left side.
(x−6)2=12
Step 5: Take square root.
x−6=±√12
Step 6: Add 6 to both sides.
x−6+6=6±√12
x=6±√12
x=6+2√3 or x=6−2√3
Ben drinks 3 1/2 liters of tea every 40 minutes.
This means that he would drink 1 3/4 of tea every 20 minutes (divide both sides by 2).
Now, let's multiply each side by 3.
1.75 * 3 = 5.25 (aka 5 1/4)
20 * 3 = 60 minutes (an hour)
He drinks 5 1/4 liters of tea in one hour.
