Because the 5 rounds 9 to a 10, making the 7 an 8, hence:
342.8
round the 2 to a 3 because the 8 round it up, making it 343

<h2>Explanation:</h2>
Here we have the following inequality:
In order to graph the shaded region, we have to graph the equation of the line 
whose slope is 
and y-intercept 
. So the graph of the line is shown in the First Figure below.
To find the shaded region we need to have a look at the symbol > that indicates that the shaded region is above the graph of the line and. Since this doesn't include the symbol =, then the line is dotted. Therefore, the resulting region is shown in the second Figure.

Answer:
The correct option is D.
Step-by-step explanation:
The given equation is
According to the addition property of equality 
and 
are equivalent equations.
Use addition property of equality, add 3x on both the sides.
Therefore Sam's work is incorrect because he make calculation mistake.
According to the subtraction property of equality and 
are equivalent equations.
Use subtraction property of equality, subtract 5x from both the sides.
Therefore Roy's work is correct because he used subtraction property.
Option D is correct.
Answer:
Option C. 144 square inches is the correct answer.
Step-by-step explanation:
We have been given a square with one side with a measurement of 1 foot and we have to calculate the area in square inches.
First we know that 1 foot of length = 12 inches on scale
Therefore side of the square is 12 inches
Now the area of the square will be = (Side×Side) = (Side)²
= (12)² = 144 square inches.
So the area of the square will be 144 square inches.
Answer:
Step-by-step explanation:
Answer: A.) 2 <= X <= 6
B.) 13 < = X < = 39
Step-by-step explanation:
Given that a factory can work its employees no more than 6 days a week, that is, less than or equal to 6 days a week
And also, no less than 2 days per week. That is, greater than or equal to 2 day a week.
Let X represent the number of days an employee can work per week.
According to the first statement,
X < = 6
According to the second statement,
X >= 2
An inequality to represent the range of days an employee can work will be
2 < = X <= 6
To represent the range in hours, first convert the number of days to hour. Given that an employee can work
1 day = 6.5 hours
2 days = 2 × 6.5 = 13 hours
5 days = 6 × 6.5 = 39 hours
Therefore, the range will be
13 < = X < = 39
