[[x]] means to round down to the greatest integer less than or equal to x.
Answer:
The nearest option is -3 (negative 3)
So, Option B is correct.
Step-by-step explanation:
We need to solve the inequality 
Solving:
Step 1: Switching sides of inequality and reversing the inequality

Step 2: Adding 4 on both sides

Step 3: Dividing both sides by -3 and reversing the inequality

The nearest option is -3 (negative 3)
So, Option B is correct.
1 1/4= 1*4+1 /4. Or 5/4
In order to subtract you must have same denominator. 5/4 -3/8
Multiply 5/4 times 2/2. =. 10/8. -3/8
The difference is 7/8
Hi there! The answer is 72 guests.
To find our answer we need to set up and solve an equation. Let the total number of guests be represented by g. The cost per guest is $13.50
Therefore the cost for all of the guests will be $13.50 × g.
To find the total cost we need to add the additional fee of $540 to cover linens and tableware.
Now we've found our equation.

Subtract 540.

Divide by 13.5

Therefore, there are 72 guests. The answer is 72.
