Mike had twice as many paper birds as june. after he gave 15 paper birds to june, he had half as many paper birds as june. how many paper birds do they have in all?

Step-by-step explanation:

Begin by assigning expressions for both Mike and June.  If Mike has twice as many birds as June, then June has x birds and Mike has 2x birds.  "After he gave 15 paper birds to June" means we are subtracting 15 from what he has, which is 2x.  Therefore, the first part (or the left side of our equation) looks like this:  2x - 15 =

Now what he has left is what goes on the right side of the equals sign.  If what Mike has left is half as many as June, then 1/2x goes on the right.  Our equation then is

Combine like terms to get

Multiply both sides by 2/3 to get that x = 10.  If x is June's number of paper birds, and Mike's is 2x, then Mike has 20.  Together they have 30.

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
