If there 6 carp in the pond, and this value represents 40% of the fish in the pond, what value represents 100%

15 = total fish in the pond

Step-by-step explanation:

Number of carp = total fish in the pond * percentage of carp

We know the number of carp and the percentage of carp

Number of carp = 6 and the percentage of carp  = 40%  (in decimal form = .4)

Substitute these in

6 = total fish in the pond * .4

Divide each side by .4

6/.4 = total fish in the pond *.4/.4

15 = total fish in the pond

step-by-step explanation:

2/5+1/2=9/10

6/1-9/10=5.1

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
