Answer:
a ratio of cats to dogs is 5:3 so the total of that ratio is 8 so for every 8 animals there are 5 cats so 5/8*104=65
b. ratio of dogs to cats is 3:5 so 3 of every animal is a dog so 3/8*104 =39
and 39+65=104 as a final check = 104
this also proves that dogs are better than cats
Step-by-step explanation:
Answer: The fraction x = 1/2 or its equivalent decimal form x = 0.5
================================================
Work Shown:
AE = 2*(BD)
4x+8 = 2*(4x+3)
4x+8 = 8x+6
8-6 = 8x-4x
2 = 4x
4x = 2
x = 2/4
x = 1/2
x = 0.5
note: the first equation is set up basically saying that AE is twice that of BD; put another way, BD is half as long as AE. This is one property of midsegments. Another property is that AE and BD are parallel.
another note: if x = 0.5, then AE = 4*x+8 = 4*0.5+8 = 10 while BD = 4*x+3 = 4*0.5+3 = 5, showing that AE is indeed two times longer than BD.
