Answer:
Is rational
Step-by-step explanation:
So, adding two rationals is the same as adding two such fractions, which will result in another fraction of this same form since integers are closed under addition and multiplication. Thus, adding two rational numbers produces another rational number.
So if 54 is 100% then 200% is double therefore 200% of 54 is 108
Answer:
y = -4x -1
Step-by-step explanation:
The slope intercept form of an equation is
y = mx +b where m is the slope and b is the y intercept
y = -4x -1
Using proportions, the value of x that makes the triangle similar is of x = 14.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, we want the triangles to be similar, hence the lengths of it's sides follow the proportion given next:

Applying cross multiplication:
6x = 12 x 7
x = 2 x 7
x = 14.
The value of x that makes the triangle similar is of x = 14.
