Answer:
x = 6 cm
Step-by-step explanation:
Given ratio of sides of similar figures = a : b , then
ratio of areas = a² : b²
Here ratio of areas = 5 : 45 = 1 : 9 , so
ratio of sides = : = 1 : 3
Thus side of B is 3 times side of A
x = 3 × 2 = 6 cm
Answer: <em><u>ratio</u></em>
(a Rational number is a number that can be written as a <u>ratio</u> of two integers)
Step-by-step explanation:
By definition a Rational number is that number that can be expressed as a fraction:
Where the numerator "a" is an integer and the denominator "b" ()
Then, in other words, a Rational number is a number that can be written as a ratio of two integers.
Since the denominator "b" can be , we know that every Integer is a Rational number.
Below are some examples of Rational numbers:

Answer:
x=3
Step-by-step explanation:
In order to solve this kind of equation, you need to be able to understand what the question is asking. This question is asking what value of X will make both sides equivalent to each other?
<em>In order to find out, you need to get X by itself. </em>
The first step is to subtract 115 from both sides.
7x+115=136
-115 | -115
7x=21
Now, the X value is by itself with another value on the other. With this part, you need to divide both sides by 7.
7x=21
/7 | /7
x=3
This is because you have 7 X's and you need to have only 1 of the X's.
