Answer:
1 / x^8
Step-by-step explanation:
We know that a^b / a^c = a^ (b-c)
x^7 / x^ 15 = x^ (7-15) = x^-8
We also that that a^-b = 1/ a^b
x^-8 = 1 / x^8
Answer: n=58
Step-by-step explanation:
7(n-7)=3(2n+3)
We move all terms to the left:
7(n-7)-(3(2n+3))=0
We multiply parentheses
7n-(3(2n+3))-49=0
We calculate terms in parentheses: -(3(2n+3)), so:
3(2n+3)
We multiply parentheses
6n+9
Back to the equation:
-(6n+9)
We get rid of parentheses
7n-6n-9-49=0
We add all the numbers together, and all the variables
n-58=0
We move all terms containing n to the left, all other terms to the right
n=58
Answer:
b 5/3
Step-by-step explanation:
becouse 5/3 pound is not a unit a unit would have more like c d and a
so b is right
Answer:
One fifth is like you saying one fifth of something, so if you have 3 fifths of something it's just 3 times more than one fifth. so like 1/5 is 20% so 3/5 is 3 times more which is 60%
