Answer: See explanation
Step-by-step explanation:
7x - 2(x + 3y) + 3y
= 7x - 2x - 6y + 3y
= 5x - 3y
Will got 5x + 9y because he didn't multiply the values in the bracket by the minus sign outside the bracket. He multiplied the values by +2 rather than -2. This resulted in the wrong answer that he got.
Answer:
Minimum: 14 Maximum: 87.5 Lower Quartile: 34 Upper Quartile: 65 Median: 47.5
Step-by-step explanation:
The difference is 6 because it is what we get when we subtract 8 and 2.
Final answer: 6
Answer:

Step-by-step explanation:
If ΔABC ~ ΔDEF
Then their sides must be proportional such that:
=> 
Cross Multiplying
=> x * 6 = 8*3
=> 6x = 24
Dividing both sides by 6
=> x = 4
