Answer 1

Yes

Explanation:

Yes

Answer 2

8.4

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 * 0.7`

→→→→→ 8.4
