Answer:
x ≈ - 1.83
Step-by-step explanation:
to solve for x in the question 1.1x + 1.2x - 5.4 = -10
we have
2.3x - 5.4 = -10
collect the like terms
2.3x = -10 + 5.4
2.3x = -4.2
divide both sides by the coefficient of x
2.3x/2.3 = -4.2/2.3
x = -1.826
x ≈ - 1.83

Answer:</h3>
Option B. because all rational numbers are integers.
Have a look at the above venn diagram showing the relationship between - Real, irrational, rational, integers, whole and natural numbers.

The answer to this question would be the last choice (this data has no outliers)
Explanation: The reason for this is that an outlier is basically any number or value that kind of stands off or is very separated from a set of data.
For example, if I had the numbers 1,2,3,2,9,5,7,5,8,4 and 47, 47 would definitely be an outlier as it's significantly greater than the rest of the data.
The data shown in your question doesn't vary a lot though, (it's contained within a range of 65 and 80- no number seems to be radically different).
Answer:
- 17900 + 700
answer to the equation would be -17,200
