Answer:
2.1 plus 2 x equals 7.5
Step-by-step explanation:
The answer is 2x-8 where “the product of two and a number” is the 2x and 8 less is to subtract 8 from the 2x so your answer is 2x-8
Assuming that <em>a + 2 = y</em>, the property that was applied to arrived at <em>(a + 2)/3 = y/3</em> is the: division property of equality.
<em><u>Recall:</u></em>
What is done to both sides of an equation will determine what property of equality was applied to the equation.
- Thus, given the equation:
a + 2 = y
- The following was obtained:
(a + 2)/3 = y/3
Observing the equation stated above, we will see that both sides of the equation was divided by three. This makes both sides equal.
Therefore, assuming that <em>a + 2 = y</em>, the property that was applied to arrived at <em>(a + 2)/3 = y/3</em> is the: division property of equality.

Answer:
456
Step-by-step explanation:
Let X be the SATscore scored by the students
Given that X is normal (1000,200)
By converting into standard normal variate we can say that
is N(0,1)
To find the top 10% we consider the 90th percentile for z score
Z 90th percentile = 1.28
i.e. only students who scored 456 or above only should be considered.
