To put this into an equation, we can make x the amount of two year old's there are.
x+2x+2x=45
5x=45
x=9
9 two year old's, 18 three year old's, and 18 four year old's.
diagonal for rectangle= sqrt( A^2 +b^2)
diagonal for square = sqrt(2) * Side
rectangle diagonal = sqrt (14^2+7^2) = 15.65 inches
square diagonal = sqrt(2) * 7 = 9.90 inches
9.9 *2 = 19.8
the diagonal of the rectangle is not two times the length of the square
B the answer to the problem
Answer:
A = 40/n
Therefore, she gave each friend 40/n ounces of jelly beans.
Step-by-step explanation:
Given;
Total amount of jelly beans To = 3 pounds = 3×16 ounces = 48 ounces
Total amount kept for family Ta = 8 ounces
Total amount given to friends = Ti
Number of friends = n
Amount given to each friend = A
Ti = To - Ta
A = Ti/n = (To-Ta)/n
A = (48 - 8)/n
A = 40/n
Therefore she gave each friend 40/n ounces of jelly beans.
