Given m|n, find the value of x.

>m
please help me
=======================================================
Explanation:
The information that m || n is not needed or used, so I'm not sure why your teacher put that in there.
The angles shown are a linear pair. They are adjacent and they are supplementary. They form a straight angle.
Supplementary angles add to 180.
(x-17)+(5x-1) = 180
x-17+5x-1 = 180
(x+5x)+(-17-1) = 180
6x-18 = 180
6x = 180+18
6x = 198
x = 198/6
x = 33
---------
Extra info:
if x = 33, then,
x-17 = 33-17 = 165x-1 = 5*33-1 = 165-1 = 164Adding the angles gives 16+164 = 180 which helps confirm our answer.

Answer:
D. m = -15/1
Step-by-step explanation:
Slope Formula-
m = (y2-y1)/(x2-x1)
Using two random points-
(-1, 13) (0,-2)
-1 = x1
13 = y1
0 = x2
-2 = y2
m = (-2 - 13)/(0-(-1))
m = -15/1
Marcy's Cafe has regular coffee and decaffeinated coffee. This morning, the cafe served 60 coffees in all, 33 of which were regular. What percentage of the coffees were regular?
Answer:
55%
Step-by-step explanation:
Percentage of regular coffees = [tex]\frac{33}{60}[/tex] × 100%
= 55%
Answer:
55%
Step-by-step explanation:
To find the percentage of regular coffees, divide 33 by 60, and multiply that by 100:
(33/60) x 100
0.55 x 100
= 55
So, 55% were regular
if the measure of angle 6 is 28⁰ then the measure of angle 3 is
Answer: 62
Step-by-step explanation:
Every triangle’s angles add up to 180. since it’s a right triangle one of the angles is 90 degrees and the other is 28 degrees. so then you have to find the other angle which would made it add up to 180. which is 62.
28+90=118
180-118=62

280 ml as a percentage of 140 l.
Answer:
280 ml as a percentage of 140 l is 0.2%
Step-by-step explanation:
Note that 1 liter = 1000 millilitersTo find a percentage of a number divide the number by the total and multiply the quotient by 100%∵ There is an amount of 280 ml
∵ The total amount is 140 l
→ Change the liter to milliliters using the 1st point above
∴ 140 l = 140 × 1000 = 140000 ml
∴ 140 l = 140,000 ml
→ Now divide the amount by the total, then multiply the quotient by 100%
∵ 280 ÷ 140,000 = [tex]\frac{1}{500}[/tex]
∵ [tex]\frac{1}{500}[/tex] × 100% = 0.2%
∴ 280 ml as a percentage of 140 l is 0.2%
Julio bought a backpack for $39.95 and 2 belts for $17.99 each. The sales tax is 6%. How much did Julio spend for all the items, including tax
Answer:
$80.49
Step-by-step explanation:
39.95 + 17.99 x 2
17.99 x 2 = 35.98
35.98 + 39.95 = 75.93
75.93 + 6% = 80.49
subtract: 3a ( a+ b+ c) - 2b (a- b+ c) from 4c (-a + b + c)
Answer:
4c^2 - 3a^2 -7ac +6bc -ab
Step-by-step explanation:
solve first 3a( a + b + c) - 2b ( a+ b +c)
which is = 3a^2 + 3ab + 3ac - 2ab - 2b^2 -2bc
there for 4c(-a + b +c) -( 3a^2 + 3ab + 3ac - 2ab - 2b^2 - 2bc)
= -4ac-3ac +4bc+2bc -3ab+2ab + 4c^2 -3a^2
=4c^2 - 3a^2 -7ac +6bc -ab

It's not a linear equation, but its grapg is a straight line.
It is a linear equation, and its graph is a straight line.
It's not a linear equation and its graph is not a straight line.
it's a linear equation, but the graph is not a straight line
Answer:
The given line y = -2x +30 is a straight line as it is written in the
form y = mx + b.
The graph of the line y = -2x +30 is also straight and attached below.
Step-by-step explanation:
Given the equation
y = -2x +30
We know that the slope-intercept form of the line equation is
[tex]y=mx+b[/tex]
Where m is the slope and b is the y-intercept
The graph of y=mx+b is a straight line as it is the line equation.Writing the equation in the slope-intercept form
y = -2x +30
y = mx + b
Thus,
m = -2
b = 30
Thus, the given line y = -2x +30 is a straight line as it is written in the
form y = mx + b.
The graph of the line y = -2x +30 is also straight and attached below.
Write the standard form of the line that has a slope - 3/4 intercept of -2Include your work in your final answer Type your answer in the box provided or use the upload option to submit your solution

Use the diagram to answer the question
Use a sample n = 500, = 0.90, and a 95% confidence level to construct a confidence interval estimate of the population proportion, p.
0.887 < p < 0.913
0.878 < p < 0.922
0.874 < p < 0.926
0.817 < p < 0.983
Answer:
0.874 < p <0.926
Step-by-step explanation:
The population proportion lies in the interval 0.8738 < p < 0.9262 with 95% confidence.
What is a confidence interval?The mean of your estimate plus and minus the range of that estimate constitutes a confidence interval. Within a specific level of confidence, this is the range of values you anticipate your estimate to fall within if you repeat the test. In statistics, confidence is another word for probability.
Given, A sample having n = 500, p = 0.90, and we have to construct a 95% confidence interval.
We know the confidence interval for a population proportion is,
CI = [tex]P \pm Z_\frac{\alpha}{2}\sqrt{\frac{P(1 - P)}{n}}[/tex].
CI = 0.9 ± 1.96×{√(0.9×0.1)/500}.
CI = 0.9 ± 1.96×√(0.09/500).
CI = 0.9 ± 1.96×0.0134.
CI = 0.9 ± 0.0262.
Therefore, 0.9 - 0.0262 < p < 0.9 + 0.0262.
0.8738 < p < 0.9262.
