45/100 = 9/20
Work: divide by 5
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
I think it's 12x.
I'm not a 100% sure though, but I hope this helps. =^D
Answer: 320ft^3
Step-by-step explanation:
Assuming the pyramid is just a normal rectangular pyramid and isn't made of stairs...
10x8x12/3 = 320 ft^3
Answer:
B.
Step-by-step explanation:
Let's call x the number of pens and y the number of notebooks that Monique can buy.
If each pen costs $2 and each notebook costs $3, so she is going to spend 2*x on pens and she is going to spend 3*y on notebooks.
Additionally, she is going to spend a maximum of $36. so:
2x + 3y
36
It means that the line that separated the region is:
2x + 3y = 36
This is the same that a line that passes for the points (0,12) and (18,0) or the line of the region B
