To do this, simply divide 15 by 105 multiplied by 100%.
So, we have:



--- approximated
Answer:
Step-by-step explanation:
Given the equation:
1/5 × (x - 2) = 20
First step to solving the equation is
By multiplying both sides by the value of 5.
That will give,
x - 2 = 100
x = 100 + 2
= 102
5/6(x-1)=4
(x-1)=(4*6)/5
x-1=24/5
x=24/5 + 1
least common multiple=5
x=(24+1*5)/5
x=29/5
Answer: x=29/5
To check:
5/6(x-1)=5/6(29/5 -1)=5/6[(29-5)/5]=5/6(24/5)=(5*24)/(6*5)=120/30=4
Answer:

Step-by-step explanation:
According to the Remainder Theorem; when P(y) is divided by y-a, the remainder is p(a).
The first polynomial is :
When p(y) is divided by y-5, the remainder is

When the second polynomial:
is divided by y-5.
The remainder is;


The two remainders are equal;
