Answer:
Step-by-step explanation:
<u>Find b first:</u>
- b = 3/x + 3/y
- b = (3x + 3y)/xy
<u>Find 1/b:</u>
- 1/b = 1 : (3x + 3y)/xy
- 1/b = xy / (3x + 3y)
2=2
63= 3* 3* 7
14= 2*7
LCM (2,63,14)= 2*3*3*7= 126
The least common multiple (LCM) of 2, 63, and 14 is 126~
Option A: 
is the solution of x
Explanation:
The given expression is 
We need to determine the value of x.
The value of x can be determined by solving the expression for x.
Taking LCM , we get,
Since, the denominator is common for both sides of the equation, let us cancel the denominator.
Thus, we have,
Multiplying the terms within the bracket, we get,
Adding the like terms, we get,
Adding both sides of the equation by 13, we have,
Dividing both sides of the equation by 18,
Simplifying, we get,
Thus, the solution is
Therefore, Option A is the correct answer.
We, know that
the area of a pizza is equal to the area of a circle
so
area of a circle=pi*r²
diameter=18 in
radius=diameter/2-----> r=18/2------> r=9 in
area of a circle=pi*9²------> 254.34 in²
the answer is
254.34 in²
The insurance pay will pay $10,000 toward Bob's expenses, $10,000 toward the wife and daughter's expenses, and John will be responsible for paying $2,500. The 10/20 insurance covers $10,000 for each person medical expense but only covers the total of $20,000 medical expense. In this case, the insurance can cover $10,000 of Bob's medical expense, $9,000 of his wife's medical expense. Lastly<span>, the insurance can cover $1,000 of his daughter's medical expense.</span>
