Answer:
The answer, is: A specific type of measurement.
Explanation:
Because... ground Truth, means... to always be in the moment and use the technique grounding and to be truthful.
There were 270*100/30 = 900 total finishers. 90% completed the marathon, so 900*100/90 = 1000 began the marathon. 1,000 runners total.
Based on the calculations, the value of x and y in this equation are both equal to 5.
<h3>What is a system of linear equations?</h3>
A system of linear equations can be defined as an algebraic equation of the first order that has two (2) variables with each of its term having an exponent of one (1).
<u>Given the following data:</u>
x + y = 10 .....equation 1.
x = 5. .....equation 2.
<h3>How to evaluate an equation.</h3>
In order to evaluate the given mathematical equation, we would substitute equation 2 into equation 1 as follows:

y = 5.
