Answer:♀️
Step-by-step explanation:
"12" represents Mike's original distance from his home. As he rides, this distance decreases by 2 miles/minute (which is rather unlikely, as that'd be 120 mph).
9 (a - b) + 5 (2a - 2b)
mutiply the first bracket by 9
(9)(a)= 9a
(9)(-b)= -9b
mutiply the second bracket by 5
(5)(2a)=10a
(5)(-2b)= -10b
9a-9b+10a-10b
9a+10a-9b-10b ( combine like terms<em>)</em>
Answer : C. 19a - 19b
Answer:
The median is 6
Step-by-step explanation:
Place all numbers in order from least to greatest:
2,3,5,5,6,6,6,6,7,7,7,9
Start by counting off the numbers evenly on each side:
5,5,6,6,6,6,7,7,
6,6,6,6,
6,6
If you are left with 2 numbers after evenly counting off numbers, then right what is in between the two numbers:
6
