To know how to do this set up the question:
63/x = 60/100
63*100=60x
6300/60=x
x=105
When you multiply a same number but with different powers, you can simply add the powers together. So, in your question, add the powers -1 and -7 together.
7^(-1) x 7^(-7) = 7^(-8)
When you divide a same number but with different powers, you subtract the power at the top with the power from the denominator. So, -8 - (-7) = -1.
7^(-8) / 7^(-7) = 7^(-1)
So your answer would be 7^(-1).
Hopefully my explanation was clear?
Answer:
-6m^4-m^3
Step-by-step explanation:
First you move the parenthesis then you group the like terms after you group the like terms you get 
which is adding the similar elements and after you add similar elements you get -6m^4-m^3. Srry if this makes no sense
Answer:
Step-by-step explanation:
I honestly don’t know sorry
Answer:
no
Step-by-step explanation:
(4, -3) when plugged into the inequality x + y < 1 is not true
4 + (-3) < 1 is not true because 1 is not less than 1
