Answer:

Step-by-step explanation:
-0.4(3i + 4i) - 0.3(-2i + 5j) + 0.2(-
+
j)
-1.2i - 1.6j + 0.6i - 1.5j -
i + 0.5j
Converting to fraction form;

<u>Solving the i part;</u>
= 
<u>Solving the j part;</u>
j
So -0.4a - o.3b + 0.2d =
- 
Length of the median would be: a+b / 2 = 19+38 / 2 = 57/2 = 28.5
Using a calculator I put 1,284/26=49.384615385. Rounded to tenth: 49.4 :)
Let x = the number of green apples, let 4x = the number of red apples
4x + x = 50 Set up the quation
5x = 50 Combine like terms
---- ---- Divide by 5 on both sides to get x alone
5 5
x = 10 green apples
4x = 4(10) = 40 red apples
40 - 10 = 30. Suzanne bought 30 more red apples than green apples.
I think the answer is: 2010
