Question 12395: I need this answer very quickly please.
One day I called two friends and invited them to a party. The next day, each of my two friends called and invited two more friends to the party. The next day, each of the people who had been invited thus far called and invited two more friends to the party. If this went on for fifteen days, how many people were actually called and invited to the party on the fifteenth day?END

Question 13371: There are 4 cups with 36 bolts in each cup. The following number of bolts are taken from each cup as follows: 1st cup 1/8, 2nd cup 3/4, 3rd cup 1/2 & 4th cup 5/8. What fraction of bolts have not been taken.
This is how I worked through it:
1) I added the 4 cups together. (144 bolts)
***********************************************
2) I multiplied the number of bolts taken from each cup with the initial number of bolts in each cup: 1/8*36= 4.5, then I subtracted the sum from the initial number of bolts: 36-4.5= 31.5, 2nd cup: 3/4*36= 27, 36-27= 9, 3rd cup: 1/2*36= 18, 36-18= 18, 4th cup: 5/8*36=22.5, 36-22.5= 13.5
***********************************************************************
3) I added all the bolts from step 2: 31.5+9+18+13.5= 72
***********************************************************************
4) I divided the total number of bolts from step 3 and 1: 72/144= .5
MY ANSWER: 1/2 or .5

Question 13774: The sum of two numbers is 15. Three times the first number is equal to 5 times the second number minus 11. What is the equation and what are the two numbers?
solution
let the numbers be X and Y.
then accourding to first condition their sum willbe
x+y= 15 (1)
accourding to second condition we have
3x= 5y-11 (2)
now we can solve the problem by simultaneously solving equations or by putting values of is equation in second
that is
from the first equation
x= 15-y
putting value of x in equation 2
we get
3(15-y)= 5y-11
45-3y= 5y-11
45+11= 5y+3y
56= 8y
or
8y= 56
y= 56/8
dividing by 8 on both sides
y= 7
now for x
put the value of y in equation (1)
that is
x+7= 15
x= 15-7
x= 8
hence x= 8 and y= 9
