Answer:
(n +54)/9 = 21; 135= n
Step-by-step explanation:
(n+54)/9 = 21
n+54/9 *9= 21*9
n+54-54 = 189-54
n= 135
the first part is simply recognizing the order its written and the words used.
So to start off with, they use the turn "a number" so we know there's going to be some form of a variable. From there it says "increased by" rather than "multiplied" or "doubled" or something of that nature, so we know its adding 54 rather than multiplying. Then, the next part says that "the sum" which is another key term for addition, "is then divided by 9". So we can assume so far that a variable plus 54 is added together to get a number, which is then going to be taken and divided by 9. The last part says "the result is 21", which simply means that we need to end up with 21.
So once we gather all this information, we can put it together as so: (n +54)/ 9 = 21.
I put parentheses around the n + 54 to make sure that the equation is following the system of equations (PEMDAS).

Answer:
x = 6
Step-by-step explanation:
The median is half the sum of the parallel bases , then
[tex]\frac{2x+4+10x-50}{2}[/tex] = 13 ( multiply both sides by 2 to clear the fraction )
12x - 46 = 26 ( add 46 to both sides )
12x = 72 ( divide both sides by 12 )
x = 6

Answer:
64 1/2
Step-by-step explanation:
6(1/4+5/2)-2
parethesis first 1/4 +5/2 make them the same denominator 1/4 + 10/4 = 11/4
then 6 or 6/1 time 11/4 = 66/4= 16 1/2 - 2 = 64 1/2 i havn't done fractions in awhile so im not a 100% certain

How do I find the answer
Answer:
x = 95 degrees
Step-by-step explanation:
First find the missing angle next to 142 (we will call it y)
y +142 = 180
subtract 142 from both sides
y = 38 degrees
then we know a triangle must have 180 degrees
so
47+38+x = 180
subtract 47 and 38 from 180
x = 95
hope this helps and makes sense :)
If (-10,8) is a point on the terminal side f a angle 0 in standard position what is the value of tan0?
Answer:
The value of the tangent is [tex]-\frac{4}{5}[/tex].
Step-by-step explanation:
Let be [tex]A(x,y) = (-10, 8)[/tex] on the terminal side of an angle in standard position and let be [tex]O(x,y)[/tex] the origin of the angle and the origin of the Cartesian plane. By definition of tangent, we make use of the following expression:
[tex]\tan \theta = \frac{y_{A}-y_{O}}{x_{A}-x_{O}}[/tex] (1)
Where:
[tex]x_{A}, x_{O}[/tex] - x-Coordinates of point A and point O.
[tex]y_{A}, y_{O}[/tex] - y-Coordinates of point A and point O.
If we know that [tex]x_{A} = -10, x_{O} = 0[/tex], [tex]y_{A} = 8[/tex] and [tex]y_{O} = 0[/tex], then the value of the tangent is:
[tex]\tan \theta = \frac{y_{A}-y_{O}}{x_{A}-x_{O}}[/tex]
[tex]\tan \theta = \frac{8-0}{-10-0}[/tex]
[tex]\tan \theta = -\frac{4}{5}[/tex]

The total cost for dinner last night was 43.57. Tax is 9% and I want to leave a 20% tip. What will my final total be including tax and tip
Answer: $56.20
Step-by-step explanation:
Both the tax and the tips will be based on the total cost:
Tip = 43.57 * 20%
= $8.71
Tax = 43.57 * 9%
= $3.92
Total = Cost + Tip + Tax
= 43.57 + 8.71 + 3.92
= $56.20

Austin thinks that the inequality 6x - 4y is greater than or equal to 10 should be shaded above the boundary

symbol. Is he correct? Explain.
Answer:
no, you shade below the line. you'd have to turn the inequality into slop intercept form, meaning y[tex]\leq[/tex]3/2x-5/2.

Use Desmos graphing calculator
Answer:
x = -2y^2
Explanation Part 1:
It's not vertical, and thus it's not a standard (y = ax^2 + b) parabola.
This must mean it's either x = 2y^2 or x = -2y^2
Explanation Part 2:
You can test values into either one to check if it works
Take (-2, 1) for example, doesn't have to be a precise coordinate pair:
First Equation
x = 2y^2
-2 = 2(1)^2
-2 = 2(1)
-2 = 2
DOESN'T WORK!
Second Equation
x = -2y^2
-2 = -2(-1)^2
-2 = -2(1)
-2 = -2
IT WORKS!
