Answer:
1/6p - 4/5
Step-by-step explanation:
-2/3p + 5/6p = 1/6p because -2/3 is equal to -4/6 and 5/6 - 4/6 is 1/6
you can combine them because they both have p
1/5 - 1 = -4/5
1 = 5/5
1 - 5 = 4
1/5 - 5/5 = -4/5
you can combine the others because they both lack a variable
1/6p - 4/5
but make sure the p is not on the bottom, it's just like that because of keyboard. just put the p like it already was in the expression.
a) 4k^2 + k – 5) + (7k^2 + 2k + 6)
11k^2 +3k +1
Choice A
Answer:
Step-by-step explanation:
11. 7 × 8 = 8 × 7 [commutative property]
12. 5 × 0 = 0 × 5 [commutative property]
13. 5 × (0 + 8) = (5 × 0) + (5 × 8) [[distributive property]
14. (7 × 1) + (7 × 9) = 7(1 + 9) [distributive property]
15. 6 × 1 = 6 [Identity property of multiplication]
16. 9 × (10 × 1) = (9 × 10) × 1 [[commutative property]
17. 1 × 10 = 10 [Identity property]
18. 7 × 1 = 7 [Identity property]
19. 4 × 8 = 8 × 4 [commutative property]
20. 4 × (1 × 2) = (4 × 1) × 2 [commutative property]
