<span>At the city park there were 15 blue jays, 6 cardinals, and 9 mockingbirds. 

6 mockingbirds is 2/3 of 9
so 2/3 of 6 is 4 cardinals 

5 blue jays is 1/3 of 15
so 1/3 of 6 cardinals is 2 cardinals

There are 20 cardinals, how many mockingbirds.
the ratio is 2/3, so 20/30 is your answer

hope this helps</span>

I NEED ANSWER ASAP PLZZZZZ
Sav [38]

Answer:

k = 4

Step-by-step explanation:

Rearrange so that like terms are on either side of the equation

4k - 2k - 2k + 2k = 5 + 3

Simplify

2k = 8

Divide both sides by two to make k on its own

k = 4

You are correct, well done!
