- a • [- b] = c
[a] • [- b] = - c or [-a] • [b] = - c (either one is fine)
[- c] / - b = a
[- c] / [b] = - a
Answer:
divide by 4, 12, 21
Step-by-step explanation:
first, look at 20, and 5. How do you get there?
well, there are 2 possible ways.
20/4=5, or 20-15=5
we take it into the next pattern to get
44/4=11, and 44-15=29.
so now we know that the rule is to divide by 4

36/4 = 12
84/4=21
Answer:
45
Step-by-step explanation:
4/5 t = 36
Divide both sides by 4/5
4/5 / 4/5 t = 36/4/5
4/5 cancels 4/5
Also flip the divisor 4/5
t = 36x5 / 4
= 180/4
= 45
