Answer:
-6 4/5
Step-by-step explanation:
A/2.8 • 2.8
Division and multiplication are opposite of each other, meaning they cancel out.
This means that a/2.8 • 2.8 is a.
No matter what a is equal to, the answer is a itself.
Once a is divided by 2.8, it is then multiplied by 2.8, bringing us back to the original value of a.
Answer:
a/2.8 • 2.8 = a
Hope this helps!
Answer:
6 * 10^2
Step-by-step explanation:
Simplify : (4.2×10^7)÷(7×10^4)
(4.2 × 10^7) / (7 × 10^4)
From indices : 10^a ÷ 10^b = 10^(a - b)
(4.2 / 7) * 10^(7-4)
0.6 * 10^3
= 6 * 10^2
Hence, (4.2×10^7)÷(7×10^4) = 6 * 10^2
