Put the number of daughters as x and number of sons as y.
For the first half of the statement:
Number of sisters any daughter has = x-1 ( because you can't be your own sibling)
Number of brothers = y
y=x-1.
For the second half:
Number of sisters any son has = x
Number of brothers any son has = y-1
3(y-1)=x
Solve as system of equations.
3y-3=x
3(x-1)-3=x
3x-3-3=x
2x=6
x=3
y=x-1=3-1=2
3 daughters and 2 sons.
Hope this helps!

Answer:
40.5 Please mark me as brainliest
Step-by-step explanation:
x=(7/8)-(1/5)
x=(7*5-1*8)/40
x=(35-8)
x=(27/40)
60 min= 1hr
(27*60)/40
=40.5 min
Your answer is,
1 2/7-5/7 = 9/7-5/7 =4/7
Answer: There are 80 nickels, 120 dimes, and 300 quarters.
Step-by-step explanation:
Since for every 2 dimes there are 5 quarters, and for every 2 nickels there are 3 dimes, there can be 4 nickels, so there will be 6 dimes and 15 quarters. When you add all of them up it equals 25, so you take 500 divided by 25, and that equals 20, so you take the 4 nickels, 6 dimes, and 15 quarters times 20.
20 x 4 = 80
20 x 6 = 120
20 x 15 = 300
Hope this helps! :D
The reason that would support that is ∠B ≅ ∠B , the reflective property of equality.
<h3>What are similar triangles?</h3>
Similar triangles are triangles that have their corresponding angles equal and the ratio of their corresponding lengths also equal.
Analysis:
triangle BDE and BAC share the same angle B
which means ∠DBE = ∠ABC.
The reflective property of equality says a number is always equal to itself. Therefore, ∠B ≅ ∠B
