Answer:
It's B
Step-by-step explanation:
-a +5a-a =3a
+4-6=-2
= 3a-2
12w + 13¹/₃ = -6
<u> - 13¹/₃ - 13¹/₃
</u> <u>12w</u> = <u>-19¹/₃
</u> 12 12<u>
</u> w = -1¹¹/₁₈
So first find the factors of the denomenatores
14=2 times 7
7=7
21=7 times 3
common one would be having at least one 2, one 7, and one 3
find what numbers can be made by all of them
2 times 7 times 3
2 times 7
7
7 times 3
they are all in it
2 times 3 time s7=42
common denoomenator is 42
For this case we have:
One hundred equals 100
three times fives equals
So, rewriting the expression we have:

Answer:
One hundred divided by the quantity three times fives is equivalent to
