Answer :
84x-16y-10.6
Solution :
2(14x-3y+28x+12.2-5y-17.5)
= 28x-6y-56y+24.4-10y-35
= 84x-16y-10.6
16(3b−0.25)
=(16)(3b+−0.25)
=(16)(3b)+(16)(−0.25)
=48b−4
Answer:

Answer:
Plan C=12 weeks for 30 miles walked.
Step-by-step explanation:
This is a constant rate of change...the number of miles each week increased by 10 each time; the number of weeks was divided each time by 2. To find Plan C, divide 24/2, which is 12.
Hope this helps! Have a great day C:
Answer:
Step-by-step explanation:
To get from the top square to the bottom square, multiply by - 3 So the middle position of the bottom square is - 30. If you solve all of the top square, you can get the bottom square easily enough.
The diagonal of the top square adds to 13 + 10 + 7 = 30
The top line of the top square must add to 30 as well 13 + 11 + 6. Put 6 in the middle position.
The right hand vertical line must add to 30. 11 + 7 + 12 = 30
The middle row must add to 30. 10 + 12 + 8. 8 goes in the left position of the middle row.
Let's summarize what we have so far.
13 6 11
8 10 12
7
We can fill in the last two spaces by adding to 30
13 6 11
8 10 12
9 14 7
That completes the top magic square.
To get the bottom magic square, multiply by -3
- 39 - 18 -33
-24 -30 -36
-27 -42 -21
