A flock of pigeons flew to a tall tree. Some of them perched on the branches, others landed under the tree. The pigeons sitting on the branches called to those under the tree, “if one of you joins us, there will be twice as many of us than you.” Then, those under the tree answered, “It’s true, but if one of you joins us, there will be as many of us as of you. Please help.

There are 7 on the tree, and 5 below

Step-by-step explanation:

If one left the bottom, there would be 8 on top and 4 below. Therefore, twice as many. If one left the top it would be both 6 and 6.

Step-by-step explanation:

We got equations below:

Eliminate b and solve for t:

Then find b:

answer: no picture is

step-by-step explanation:

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
