Answer:
Step-by-step explanation:
It's an arithmetic sequence.
The difference is constant.
The explicit formula of an arihmetic sequence:
Substitute:
<em>use distributive property</em>
6:3 = 6/3 = 2
13 to 4 = 13:4 = 13/4 = 3.25
19/2 = 9.5
15 to 10 = 15:10 = 15/10 = 1.5
8:2 = 8/2 = 4
From the least to the greatest:
15 to 10 , 6:3, 13 to 4, 19/2
I hope this explains it.
I think your teacher's just asking for the multiplied out version, so there's no work to do
3. -2(3m + 9) = -6m - 11
4. -6(z-1) = -6z + 6
5. -(m +1) = -m - 1
6. -(x+4) = x = 4
7. b(a- 6) = ab - 6b
8. 7a(3b -2c + 4) = 21ab - 14ac +28a
9. 1/2(8x + 2) = 4x + 1
10. 2/3(1/4x -6) = 1/6x - 4
Answer:
-8(5b+2)-7(b-5)
first, use distributive property to get:
-40b-16-7b+35
then, use combine like terms to simplify:
-47b+19
that's your answer!
