The answer is -77 pounds :)
Answer:
The answer would be 35/12 or 2 and 3/4
Step-by-step explanation:
First we need to convert the fractions, so that they have the same denominator. A common denominator is 12. So, we mulitply 4 by 3 (because 4 X 3 = 12) and we do the same thing for 9. This makes the fraction 27/12. Now we mulitply 2/3 by 4 (because 3 X 4 = 12) and we also multiply 4 by 2 which gives us 8/12. Add 27/12 + 8/12 and you get 35/12 which can be simplified to 2 and 3/4.
Answer:
[(a + b), c]
Step-by-step explanation:
Midpoint of a segment with extreme ends represented by ordered pairs 
and 
,
Midpoint = 
It is given that extreme ends of the segment QS are Q(2b, 2c) and S(2a, 0)
Coordinates of the midpoint of QS will be,
= 
= [(a + b), c]
Therefore, ordered pair representing the midpoint of QS will be [(a + b), c].
For this item, I assume that Svetlana's hair is 4 cm long and she wanted it to be at least 7 cm long.
We let x be the number of months it will take for her hair to be 7 cm long. The sum of the product of x and the rate and the initial length should be at least 7. Mathematically,
1.51x + 4 ≤ 7
Note: 0 - (-1) = +1.
