Answer:

8.4

Step-by-step explanation:

1 orange → x

1 apple → y

\frac{\begin{matrix}\space\space&5n&+&7y&=\textbf{6.90}\\ +&5n&+&20y&=\textbf{16.00}\end{matrix}}{\begin{matrix}\space\space&\space\space&\space\space&\space\space&\textbf{+13y = +9.1}\end{matrix}}\\y = 0.7

↓

3n + 12y = 9.6\\3 (n+4y) = 3 (3\cdot2)\\x + 4y = 3.2\\5 (n+4y) =5 (3\cdot2)\\5x + 20y = 16

12 apples → 12 \times 0.7

→→→→→ 8.4

Find the area of the figure. Show your work. (WILL GIVE BRAINLIEST TO CORRECT ANSWER)
torisob [31]
To find the area of the figure you first have to split them up. To find the area for the triangle do 30 x 34 x 16= 16320
Then you find the area of the other shape:
30 x 30 x 16 x 40 = 576000
Then you add them together to get the answer:
576000+16320=592320
So, the answer is 592,320

I hope this helps:)
