Operations With Fractions
Simplify the following operations:
[tex]\displaystyle -5\frac{1}{4}-\left(-7\frac{1}{2}\right)[/tex]
Convert the mixed fractions to improper fractions:
[tex]\displaystyle 5\frac{1}{4}= 5+\frac{1}{4}=\frac{21}{4}[/tex]
[tex]\displaystyle 7\frac{1}{2}=7+\frac{1}{2}=\frac{15}{2}[/tex]
Substituting:

Simplifying:
[tex]\displaystyle -5\frac{1}{4}-\left(-7\frac{1}{2}\right)=-\frac{21}{4}+\frac{15}{2}[/tex]
Amplifying the second fraction by 2:

If the ordered a pair (6,2) is the solution to the system, what does that mean?
It means that the point (6,2) is on both graphs at the same time. In short, it is the intersection point of the two graphs.
Algebraically, the ordered pair (x,y) = (6,2) makes all of the equations in the system to be true equations. A true equation is one where it simplifies to have the same number on both sides.
A system with at least one solution is considered a consistent system. If there is only one solution, then the system is also considered independent.

Which inequality best represents that ice cream at −3°C is cooler than ice cream at 1°C? (4 points)
a
−3°C > 1°C
b
−3°C 3°C
d
1°C < −3°C
Answer:
-3° C < 1°C is the correct option.
Step-by-step explanation:
As we know that:
The inequality symbol '<' means 'less than'.The inequality symbol '>' means 'more than'.If someone says that something is cooler than the other thing, it indicates that it is lesser than the other based on its temperature.
As the ice cream at −3°C is cooler than ice cream at 1°C, it indicates that temperature -3° C < temperature 1°C.
Therefore, -3° C < 1°C is the correct option.

Cheryl wants to find the number of hours seventh-graders do homework each week. There are 297 boys and girls in seventh grade. If Cheryl randomly surveyed 50 girls in the entire school to find the number of hours seventh-graders do homework each week, describe why she would get a biased sample
Please help ASAP
Note that Cheryl wants to find the number of hours seventh grade boys and girls spend on homework each week.
There are multiple causes of a biased sample. Two of the most obvious ones I find are:
1. She's surveying girls, but she is trying to get data on the number of hours all seventh graders (boys and girls) spend.
2. She's surveying 50 girls from the entire school, although she is trying to get data on seventh graders only.
Which system is most easily solved by graphing and why?
Which system is most easily solved by substitution and why?
Which system is most easily solved by elimination and why?
a. 3m - 4n = 1; 3m - 2n = -1
b. y = 4x - 2; y - 3x = 0
c. y = x; y = -x
Answer:
System A should be solved by elimination because you can easily cancel out the 3m to solve.
System B should be solved by substitution. Since the an equation for the y value is given, you can easily substitute it into the other equation.
System C should be solved by graphing. You don't have to worry about any slopes or intercepts to graph. You can graph it using only whole numbers.

They have the same area and same perimeter.
They have the same area but different perimeters.
They have different areas but the same perimeter.
They have different areas and different perimeters.
Answer:
they have different areas and different perimeters
The statement that described the areas and perimeters of the figures should be that they have different areas and different perimeters.
What is the perimeter?The perimeter refer to the closed path where it is surrounded, outlines for the two-dimensional shape for the one-dimensional length.
So here the perimeter of a circle should be known as the circumference.
Therefore, they have different areas and different perimeters.

A nutritionist collects data from 25 popular breakfast cereals. For each cereal, the number of calories per serving is plotted on the x-axis against the number of milligrams of sodium on the y-axis. The value of r for the resulting scatterplot is 0.83. Which of the following is a correct interpretation of this value?
a.Each additional calorie is predicted to add approximately 0.83 mg of sodium.
b.There is a positive relationship between calories and sodium. The relationship is weak.
c.There is a positive relationship between calories and sodium. The relationship is strong.
d.As the number of calories increases, the amount of sodium decreases. The relationship is strong.
Answer:
answer C
There is a positive relationship between calories and sodium. The relationship is strong.
Step-by-step explanation:
The following is a correct interpretation of this value is option c. There is a positive relationship between calories and sodium. The relationship is strong.
The Correct interpretation of the value:Since
A nutritionist collects data from 25 popular breakfast cereals.
The value of r for the resulting scatterplot is 0.83.
So based on this, we can say that there should be the positive relationship between calories and sodium.
And, due to this, the relationship is considered to be strong.
Hence the option c is correct.

Answer: x = 61 and y = 29
Step-by-step explanation: In this problem, notice that we
have a transversal that intersects two coplanar lines at different points.
Let's start by finding the value of y.
In the diagram, 2y and 58 are corresponding angles and if two
parallel lines are cut by a trans. corr. <'s must be congruent.
So we can setup the equation 2y = 58.
Solving from here, we find that y = 29.
Now, notice that 58 and 2x form a straight angle or a linear pair.
When two angles form a straight angle, they are supplementary.
So we can setup the equation 2x + 58 = 180.
Solving from here, we find that x = 61.
