We can write an equation to solve this:

Let x represent amount of Blue Jays.

2x + x = 21

We can simplify the equation:

3x = 21

Divide both sides by 3 to isolate x variable:


x = 7

Therefore, 7 Blue Jays.

If triangle ABC is similar to triangle PQR, find the value of x and y.
tester [92]

Answer:

x = 9

y = 6

Step-by-step explanation:

ΔABC ~ ΔPQR

Therefore, corresponding sides of these similar triangles will be in the proportional.

\frac{AB}{PQ}=\frac{BC}{QR}= \frac{AC}{PR}

\frac{6}{x}= \frac{4}{y}= \frac{8}{12}

\frac{6}{x}= \frac{8}{12}

x = \frac{12\times 6}{8}

x = 9

Similarly, \frac{4}{y}= \frac{8}{12}

y = \frac{12\times 4}{8}

y = 6
