<u>Equations</u>
We have two cases where some variable is required to be found such that some condition is met. The first case is about finding the value of a that complies:
Rearranging
Factoring:
There are two solutions:
The second case requires us to find the value of x such that
Rearranging
This second-degree equation has no real roots. We'll offer the imaginary (complex) solutions:
The answer to number 5. Is option B
Answer:
36.67
Step-by-step explanation:
11/5=2.2
let the unknown no be x
6% of x=2.2
6/100 * x = 2.2
6x = 2.2*100
x = 220/6
x= 36.67
" 100% " means "the whole thing",
and "is" can be replaced by "is equal to".
You have said "The whole thing of a number is equal to 61."
or
"61 is equal to the whole thing of a number."
The only number that 61 can be equal to is 61.
Answer:
10
Step-by-step explanation:
first turn percent into decimal,
10/100 = 0.10
then multiply 100 x 0.10 = 10
so therefore 10% 0f 100 is 10
