Answer: 7 pigeons sitting on the branches, 5 pigeons under the tree
=12 in total
Step-by-step explanation:
Upper branch has x pigeons, lower has y.
Top branch said: "If one of you flies up to us our number will be double yours":
Well, if one of the bottom branch flies up, the top branch will have x+1 birds and the bottom will have (y−1). The top will have double the bottom, so:
x+1=2(y−1)
Top branch said: "If one of us flies down to you, our numbers will be equal":
Now, the top branch will have x−1 and the bottom y+1. The numbers should be equal:
x−1=y+1
Answer:
total = $41
Step-by-step explanation:
If Julio spent $41 and now has no money that means that after spending that money he was left with $0. Having both of these numbers we can make a very simple algebraic equation to find out his total before the purchase.
total - $41 = $0
Now we simply add $41 to both sides which will give us the actual amount of the total.
total - $41 = $0
+$41 +$40
-----------------------------
total = $41
Now we can see that Julio had a grand total of $41 before making his purchases.
25+10 is the answer
In the Commutative law of addition, it says that a+b and b+a are the same which makes ab and ba equal to one another.
To prove just add 10+25 and 25+10to show that both results in 35 (aka the same answer)
You can solve it algebraically by simply adding the numbers in the parenthesis and multiplying to get 35x but if you want to solve it using distributive property exclusively then distribute as so
5x(3) + 5x(4)
15x + 20x
35x
We know, divisor * quotient = Dividend
-7 * q = 56
q = 56/-7
q = -8
So, your final answer is -8
Hope this helps!
