I worked it out as shown:
X - 3 = -5........addition property....because u add -3 to both sides
6x = 72.....either division property...because u divide both sides by 6.
or multiplication property...because u multiply both sides by 1/6
x/5 = 3.....multiplication property....because u multiply both sides by 5
You would write it as (1/10^12)
any negative exponent does the same thing
ex: x^-1 turns into (1/x^1)
I think 0 but if I am wrong I'm sorry
Step-by-step explanation:
You'll have to multiply 0.7 by 120.
120*0.7 = n
n is the number that is 70% of 120
120 * 0.7 = 84
Hope this helps :)
