Type the expression that results from the following series of steps:
Start with
t
subtract
r
, multiply by
x
, then add
p
.
Answer:
Step-by-step explanation:Given the variable n
we have to write the expression of variable n adding with 5 then multiply the product by 4 then subtract 7 from the result
add variable n with 5 is (n+5)
multiply the result by 4 is (n+5)
subtract 7 from the result is ((n+5))-7
So the expression is ((n+5))-7

Solve the following system of equations graphically on the set of axes below.
y = 2x – 2
x +y = 4
Plot two lines by clicking the graph.
Click a line to delete it.
HELP ASAP
Answer: The solution is (2, 2)
Step-by-step explanation:
We have the system of equations:
y = 2*x - 2
x + y = 4
The first step is to write both equations as linear equations in the slope-intercept form.
y = 2*x - 2
y = -x + 4
Now we have two lines, and we can just graph them, the easiest way is the replace the value of x and obtain two points that belong to the line, and then draw a line that passes through both lines.
For example with the first one, we can firt replace x by 0 to get:
y = 2*0 - 2
y = -2
Then the point (0, -2) belongs to this line.
Now we can replace x by 1 to get:
y = 2*1 - 2 = 0
y = 0
The point (1, 0) belongs to this line.
Then we can draw these two points in the graph, and just draw a line that passes through these two points.
Once you have your two lines drawn, the solution of the system will be the point in which the lines intersect.
Below, you can see the two lines graphed (the green is the first one and the red is the second one)
And we can see that they intersect in the point (2, 2)
Then the solution of the system is (2, 2)

Answer:
Three fifths
Step-by-step explanation:
Since 10 was divided by 2 to get 5,
you just do the same to the top half of the fraction.
So when you divide 6 by 2, you get 3.
So it is equal to 3/5, or three fifths.
And 3/5 is equivalent to 6/10

In the expression 3x - 4y + z, what is the
coefficient of z?
Answer:
1
Step-by-step explanation:
The coefficient is the number in front of a variable. There is a hidden coefficient of 1 in front of z. The reason it is not shown is because any number multiplied by 1 is just that number so showing the 1 is redundant.
The coefficient of z in the expression 3x- 4y +z is 1.
What is expression?A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:
An absolute numerical number is referred to as a constant.Variable: A symbol without a set value is referred to as a variable.Term: A term can be made up of a single constant, a single variable, or a mix of variables and constants multiplied or divided.Coefficient: In an expression, a coefficient is a number that is multiplied by a variable.Given:
3x - 4y + z
As, we know a coefficient is a number that is multiplied by a variable.
So, the coefficient of x is 3, coefficient of y is 4 and coefficient of z is 1.

25) Martin bought a car for 2800 and later sold it for
a 35% profit. How much profit did Martin make in
the car?
Answer:
980
Step-by-step explanation:
because the quotient of 2800 divided by 100 gives you the answer for 1% but then you multiply that answer by 35 and you get 980
980
35 percent of 2800 is 980

Question:
For every 1 litre of water used to make a medicine, 600 ml of sucrose and 150ml of saline solution are used.
Express the amount of water, sucrose and saline solution needed as a ratio in its simplest form.
Answer:
[tex]Water : Sucrose : Saline = 20 : 3 : 12[/tex]
Step-by-step explanation:
Given
[tex]Water = 1L[/tex]
[tex]Sucrose = 150mL[/tex]
[tex]Saline= 600mL[/tex]
Required
Express as a ratio to the simplest form
First convert the volume of water to mL
[tex]Water = 1L[/tex]
[tex]Water = 1 * 1000mL[/tex]
[tex]Water = 1000mL[/tex]
Express as ratio:
[tex]Water : Sucrose : Saline = 1000mL : 150mL : 600mL[/tex]
[tex]Water : Sucrose : Saline = 1000 : 150 : 600[/tex]
Divide through by 10
[tex]Water : Sucrose : Saline = 100 : 15 : 60[/tex]
Divide through by 5
[tex]Water : Sucrose : Saline = 20 : 3 : 12[/tex]
The ratio can not be further simplified

You have budgeted $4,800 for a company to complete guest satisfaction surveys for you. They charge $1,800 + $6 per respondent. How many respondents will you be able receive for the money paid?
Answer:
6
Step-by-step explanation:
There are 500 respondents will you be able receive for the money paid.
What is mean by expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The budgeted for a company to complete guest satisfaction surveys for you is, $4,800.
And, They charge $1,800 + $6 per respondent.
Now,
Let Number of respondents will you be able receive for the money paid is, x
Hence, We can formulate;
⇒ $1800 + $6x = $4800
⇒ 1800 + 6x = 4800
⇒ 6x = 4800 - 1800
⇒ 6x = 3000
⇒ x = 500
Thus, There are 500 respondents will you be able receive for the money paid.
