Subtract 3 first so it would be 7x=15
then divide by 7 so x would be approximately 2.14

Answer:
C
Step-by-step explanation:
because if you input 18.25 into the equation and solve you get and non-whole number of 2.608.
It is impossible to have 2.608 toppings on your pizza, <u>it has to be a whole number.</u>
All the other answers had whole numbers besides C, therefore C is wrong.
The length of pendulum is 2.485 feet
<h3><u><em>
Solution:</em></u></h3>
Given that,
The formula T= 2pi sqrt(L/32) relates the time, T, in seconds for a pendulum with the length, L, in feet, to make one full swing back and forth
<u><em>Therefore, the given formula is:</em></u>

We have to find the length of pendulum that makes one full swing in 1.75 seconds
So the modify the given equation to find "L"

Substitute T = 1.75 seconds and 

Thus length of pendulum is 2.485 feet approximately
