Answer:
n = 11
General Formulas and Concepts:
Order of Operations: BPEMDASEquality PropertiesVertical Angles: Angles that are across from each other and are congruentStep-by-step explanation:
Step 1: Set up equation
Vertical angles must be congruent.
(6n - 4)° = (5n + 7)°
Step 2: Solve for n
Subtract 5n on both sides: n - 4 = 7Add 4 to both sides: n = 1112 more than 8.2 times a number n answer
Answer:
98.4n
Step-by-step explanation:
12 x 8.2 = 98.4
we need to multiply 98.4 by n, BUT we do not know what n is so we put the variable n next to 98.4 (as a symbol of multiplying 98.4 by n)

Which of the following combinations cannot be the side lengths of a triangle?
1. 2.3 inches, 3.4 inches, and 3.2 inches
2. 4.8 inches, 5 inches, and 1.2 inches
3. 2.5 inches, 2.5 inches, and 2.5 inches
4. 6.7 inches, 1.1 inches, and 7.9 inches
9514 1404 393
Answer:
4. 6.7 inches, 1.1 inches, and 7.9 inches
Step-by-step explanation:
In order for three lengths to be able to form a triangle, the sum of the shorter two must exceed the longest.
1. 2.3 +3.2 > 3.4 . . . will form a triangle
2. 1.2 +4.8 > 5 . . . will form a triangle
3. 2.5 +2.5 > 2.5 . . . will form an equilateral triangle
4. 1.1 +6.7 = 7.8 ≯ 7.9 . . . will not form a triangle
_____
The symbol ≯ is "not greater than". The typeset version looks like ...

Math question plz help me
Answer:
The required equation of the line is:
[tex]y=\frac{1}{4}x-1[/tex]
Step-by-step explanation:
Given the equation
[tex]y=-4x+3[/tex]
comparing the equation with the slope-intercept form
[tex]y=mx+b[/tex]
Here,
m is the slope y is the interceptso the slope of the line is -4.
As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so
The slope of the perpendicular line will be: 1/4
Therefore, the point-slope form of the equation of the perpendicular line that also intersects the point (8, 1) is:
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-1=\frac{1}{4}\left(x-8\right)[/tex]
add 1 to both sides
[tex]y-1+1=\frac{1}{4}\left(x-8\right)+1[/tex]
[tex]y=\frac{1}{4}x-1[/tex]

The gas tank holds a total of 15 gallons of gas.how many miles can the car travel with a full tank of gas
Answer:
....
Step-by-step explanation:
Answer:
If the car gets 30 in city miles per gallon it (MPG) would be 30×15 which would be 450 miles. If its a sportier car like the Chevrolet Camaro ZL1 which gets close to 18 miles per gallon (MPG) it would be 18×15 which would be 270 miles. There is also highway miles where a standard car would get about 40 or more miles per gallon (MPG) 40×15 which would be 600 Miles. For a car like the Toyota Prius which gets 50-58 miles per gallon (MPG) in a city but 48-53 miles per gallon 58×15=870 miles and 53×15=795 miles. It depends on the car's engine, tuning, transmission, aerodynamics, etc.
Step-by-step explanation:
Different cars get different miles per gallon (MPG).

Ben wants to buy a new car stereo and he has already saved some money. He used this inequality to represent the amount he still has to save to be able to buy the stereo, where a represents the amount still left to save.
a + 212 greater-than-or-equal-to 365
If Ben saves $15 a week for the next 10 weeks, will he be able to buy the stereo and why?
No, because he needs to save at least $153, and he will only save $150 over the next ten weeks.
No, because he needs to save $577, and he will only save $150 more.
Yes, because he has already saved $365, and the stereo cost $212.
Yes, because he has already saved $212, and he will save another $150.
Answer:
No, because he needs to save at least $153, and he will only save $150 over the next ten weeks.

Answer:
∠KNC = 99°
Step-by-step explanation:
∠JNM + ∠KNC = 180 (it is a straight line)
∠KNC = 180 - ∠JNM
∠KNC = 180 - 81
∠KNC = 99°
Answer: 99°
Step-by-step explanation: They are supplementary so 180 - 81 = 99
