Answer:
The age of brothers are 4 years and 2 years respectively.
Step-by-step explanation:
We are given that the ages of two brothers have a ratio of 2 to 1. When 4 years have passed, the ratio of their ages will be 8 to 6.
Let the age of the first brother be 'x years' and the age of the second brother be 'y years'.
So, according to the question;
- The first condition states that the ages of two brothers have a ratio of 2 to 1, that means;
-------------- [equation 1]
- The second condition states that when 4 years have passed, the ratio of their ages will be 8 to 6, that means;
= 2 years
Putting the value of y in equation 1 we get;
x = 2y
x = = 4 years
Hence, the age of brothers are 4 years and 2 years respectively.
The answer is B: 6 cm. You can use guess-and-check method, and plug the possible different answers into the equation x(x+6)=72, x stands for the width.
Answer:
The value of x is 25
Step-by-step explanation:
x² when x = 5
So,
(5)² = 5 × 5 = 25
Thus, The value of x is 25
<u>-TheUnknownScientist</u><u> 72</u>
-3.3=
Multiply both sides of the equation by 6 to isolate x.
-19.8=x
Your answer is -19.8.
I hope this helps :)
If i is a zero, -i is also a zero.
The way you get a complex zero is by taking the square root of a negative number. Taking the sqrt (-1) = + and - i
