You just have to divide the number of blocks walked by the number of hours
48 / 3 = 16 blocks per hour
Given the following statements<span>
1. line RS || segment AB, ∠1=∠2
2. ∠B = ∠1
3. ∠A = ∠2
4. ∠A = ∠B
5. RA = RB
and the following reasons,
a) If lines ||, corresponding ∠'s are =
b) If two ∠'s of a triangle are =, sides opposite are =
b) If lines ||, alternate interior ∠'s =
c) Given
d) Substitution
</span>
<span>we match the statements and the reasons to enable us prove the required proof.
Statement Reason

<span>1. line RS || segment AB, ∠1=∠2 Given
2. ∠B = ∠1 </span><span>If lines ||, corresponding ∠'s are =
3. ∠A = ∠2 </span><span>If lines ||, alternate interior ∠'s =
4. ∠A = ∠B </span><span>Substitution
[because we are given that </span>

</span>5. RA = RB </span>If two ∠'s of a triangle are =, sides opposite are =
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!
Your fortune is "You can't have everything...where would you put them all?"
