PLEASE HELP I NEED TO WRITE AN EQUATION FOR THIS
2 answers:
Info -
- 6 sketchbooks
- x = original price
- $3 dollars off original price for every sketchbook
- total price of the 6 sketchbooks was $18
So, this is the equation made to solve the problem.
6(x-3) = 18
If you solve this, then you use the basic equation and integer rules and all that stuff.
6x-18=18 Distributive property to get rid of parenthesis
+18 +18 Add 18 on both sides to get rid of the extra stuff
Then, you divide by 36:
6x=36
x = $6
Good job! You are correct :D

We have to calculate the time of pendulum whose length is 140 feet.
So, we substitute L=140 into formula and to solve for t
We get t,
s
Period = 13.15 s
