15% of 45.4=6.81 this is the final answer
If you apply the linear combination method to the system like:
<span>4(.25x + .5y = 3.75) → x + 2y = 15
(4x – 8y = 12) → x – 2y = 3
2x = 18
Then you can be sure that the solution of all this system is: (9,3). Hope this si what you were looking for</span>
Answer:
To determine whether a decimal is rational or not, you need to know that...
Irrational numbers don't end and have no pattern whereas rational numbers are the complete opposite. Rational numbers end and have a repeating pattern.
Step-by-step explanation:
Here are examples of irrational numbers:
0.9384903204..... , π , √2
Examples of rational numbers:
0.777777... (is rational because it has a repeating pattern of 7) , √49
Hope this helps :)
Answer:
C. 72
Step-by-step explanation:
So imagine every straight line you see equals to 180 degrees, so given one side of the angle...180 - 108 = 72
Answer:
Step-by-step explanation:
<u><em>The question is </em></u>
Find the measure of the legs
we know that
In a 45 degrees -45 degrees -90 degrees triangle, the measure of the legs are equal
Let
a ----> the measure of one leg
Applying the Pythagorean Theorem
solve for a
Divide by 2 both sides
Simplify
