In a pet store the number of birds is 10 less than twice the number of rabbits. if the pet store has 56 birds, how many rabbits does it have?

There are 56 birds. And there are 10 less than twice the number of rabbits

let rabbits = r

2r - 10 = 56

Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS. Isolate the r.

add 10 to both sides

2r - 10 (+10) = 56 (+10)

2r = 66

Divide 2 from both sides

2r/2 = 66/2

r = 33

33 is your answer

hope this helps

step-by-step explanation:

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
