Answer:
x = 1 and y = 5
Step-by-step explanation:
Use substitution because you know that x = y - 4, and plug this into the first equation to get -10(y - 4) + 3y = 5, or -10y + 40 + 3y = 5. This is -7y = -35 so y = 5. Plug this into the 2nd equation to get that x = 1 and y = 5.

Answer: The observed ratio is different from the expected ratio.
Step-by-step explanation:
Since we have given that
Expected ratio :
Ratio of blue flowered plants to white flowered plant = 3:1
Observed results:
Number of blue flowered plants = 35
Number of white flowered plants = 14
So, Ratio of blue flowered plants : white flowered plants
So, 5:2 ≠ 3:1
Hence, the observed ratio is different from the expected ratio.
