Answer:
The variable 8. Equation is 16 + 12x = 112.
Step-by-step explanation:
We know that she spent $16 dollars on magazines, so we can put it in the equation (16 + x= ?). We also know that the total is $112, so we can also add that (16+ x= 112). We don't know how many books she got, but we do know how much they cost (16 + 12x=112. So that makes the books the variable (X).
To find the variable we need to take out the magazines from the price. 112-16=96. Now we're left with 12x=96. Now all we have to do is divide 96 by 12, which equals 8.

water to a depth of 1.8 m. Cal culate the surface area inside the tank that is not in conta
with water.
Answers
Answer:

Step-by-step explanation:
Subtract the depth of the water from the height of the tank (0.6) and use this measurement for height instead. then calculate l•h•2+w•h•2+l•w

What is the distance between the points (1,4) and (3,7)
Answers
Answer:
[tex]2\sqrt{10}[/tex]
Step-by-step explanation:
To find the distance between points, we can use the following formula:
[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2 }[/tex]
We have two coordinates; (1, 4) and (3, 7)

Margo is selling boxes of nuts to raise money for her club. She finds that 3 out of every 7 boxes of nuts are cashews. Write a ratio to represent the number of boxes of cashews to the total number of boxes sold.
Answers
Answer:
3 : 7
Step-by-step explanation:
make sure the three of on the left
The number of boxes of cashews to the total number of boxes sold is expressed as 3:7 in ratio.
What is Ratio?The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other. The general form of expressing a ratio between two quantities say 'a' and 'b' is a: b
Margo finds that 3 out of every 7 boxes of nuts are cashews.
In order to calculate the ratio of two quantities, we can use the following steps
First, we must determine the quantities for both scenarios for which we are calculating the ratio. In this situation, there are three cashews and seven boxes.
Write it as a fraction, a/b. As a result, we write it as 3/7.
Therefore, the number of boxes of cashews to the total number of boxes sold is expressed as 3:7 in ratio.

What are 3 different methods for solving systems of equations and when would you use each one? (10 pts)
How do you graph the solution set to a system of linear inequalities in two variables? (10 pts)
How do you determine if a system of linear equations has one solution, no solutions or infinitely many solutions? (10 pts)
Answers
Step-by-step explanation:
graphing.
substitution method.
elimination method.
We will use as an example the following system of inequalities:
3x +2y ≥ 5x -4
y < (1/2)x +3
For each inequality, do the following:
1. If it is not this way already, arrange the inequality so that each variable appears on only one side of the inequality. Putting the inequality into any of the standard forms will do this. It will be helpful later if you arrange the inequality so that at least one variable has a positive coefficient. (You may have to multiply by -1 (and change the sense of the inequality) to do this.)
Our example inequalities are now ...
-2x +2y ≥ -4 . . . . . or divide by 2 to get . . . . -x +y ≥ -2
y < (1/2)x +3
2. Notice the inequality symbol, and whether it includes the "or equal to" case.
the first inequality is ≥, so includes "or equal to"
the second inequality is <, so does not include "or equal to"
3. Replace the inequality symbol with an equal sign and graph the resulting equation. If the "or equal to" case is included, the line is graphed as a solid line. If it is not, then the line is graphed as a dashed line.
the first equation (-x +y = -2) is graphed with a solid line
the second equation (y = (1/2)x +3) is graphed with a dashed line
4. It is not necessary, but is less confusing, to choose a variable in the inequality (after step 1) that has a positive coefficient. Notice whether this variable is "less than" or "greater than" the stuff on the other side of the inequality.
y ≥ . . . . for the first inequality
y < . . . or . . . x > . . . . for the second inequality
If it is less than, shade the portion of the graph below (for y <) or to the left (for x <) of the line you graphed in step 3.
the second inequality has y < , so the graph will be shaded below the dashed line. It also has x > , so will be shaded to the right of the dashed line. (These are the same shading.)
If it is greater than, shade the portion of the graph above (for y >) or to the right (for x >) of the line you graphed in step 3.
the first inequality has y ≥ , so the graph will be shaded above the solid line.
5. The solution set is where the shaded areas overlap. Any point on a dashed line is not in the solution set.
_____
The graph for the example inequalities is attached. The first one is graphed and shaded in red; the second one is graphed and shaded in blue.
A system has no solutions if the lines are parallel. When solving the system, if you get a false statement (a number equal to a different number) this means there are no solutions.
Three methods of solving inequalities are the graphing method, substitution method, and elimination method.
What is inequality in math?In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to one another.
We will use as an example the following system of inequalities:
3x +2y ≥ 5x -4
y < (1/2)x +3
For each inequality, do the following:
If it isn't already set up this way, organize the inequality so that each variable only appears on one side. This can be accomplished by putting inequality into any of the accepted formats. If you set up the inequality so that at least one variable has a positive coefficient, it will be useful later. To accomplish this, you might need to multiply by -1 (and alter the inequality's sense).
Our example inequalities are now ...
-2x +2y ≥ -4 . . . . . or divide by 2 to get . . . . -x +y ≥ -2
y < (1/2)x +3
Take note of the inequality sign and whether the "or equal to" instance is present.
The first inequality is, so "or equal to" is included. The second inequality is, so "or equal to" is not included.
Create a graph of the equation that results from replacing the inequality symbol with the equal sign. The line is graphed as a solid line if the "or equal to" scenario is present. If not, a dashed line is used to represent the line on the graph.
Graphing the first equation (-x + y = -2) using a solid line
Graphing the second equation (y = (1/2)x + 3) uses a dashed line.
Choosing a variable in the inequality that has a positive coefficient after step one is not required, but it is less ambiguous. If there is an inequality, pay attention to whether this variable is "less than" or "greater than" the items on the other side.
For the initial inequality, y
In the case of the second inequality, y or x >
Shade the area of the graph below (for y) or to the left (for x) of the line you graphed in step 3 if it is smaller than.
The graph will be darkened below the dashed line since the second inequality has the value y. It will be tinted to the right of the dashed line because it also has x >. The shading here is the same.
Shade the area of the graph above (for y >) or to the right (for x >) of the line you graphed in step 3 if it is bigger than.
The graph will be shaded above the solid line because the first inequality has y.
The overlap of the colored areas is the solution set. The solution set does not include any points on a dashed line.
When the lines are parallel, a system cannot have a solution. If you get a false statement after solving the system (a number that is equal to a different number), there are no solutions.
