4x – 20 = -18
Can someone help with this
Answer:x = 1/2
Step-by-step explanation:
4x-20=-18
(Add 20 on both sides)
4x=2
(Divide by 4 on both sides)
X = 2/4
(Simplify)
X=1/2
Find the value of x please also this is geometry
Given:
A figure of a triangle.
To find:
The value of x.
Solution:
In a triangle, angle bisectors intersect each other at a point which is know as incenter. This point is equidistance form the each side.
Using the above property, we get
[tex]4x-2=6x-8[/tex]
[tex]4x-6x=2-8[/tex]
[tex]-2x=-6[/tex]
Divide both sides by -2.
[tex]x=\dfrac{-6}{-2}[/tex]
[tex]x=3[/tex]
Therefore, the value of x is 3.
Please help I have no idea what I'm doing with any of this!!
Answer: you are doing hell jesus
Step-by-step explanation:
19 e) Find the value of x. ASAP. Will give brainliest!
Answer:
X= 40
Step-by-step explanation:
A triangle always equals 180°. In order to find x, add 75 and 65,
75 + 65 =140
then divide 140 and 180,
180 / 140 = 40
then in order to make sure it's the right answer add 75,65, and 40 together. If it equals to 180, then it's the right answer.

Trevor's bank pays 1.94% simple interest. Of his principal is $241, and he left all of it in his account for 54 days. How much interest will Trevor earn?
9514 1404 393
Answer:
$0.70
Step-by-step explanation:
The interest is computed using the formula ...
I = Prt
where r is the annual rate, and t is the time in years. Banks compute interest using "ordinary interest", which assumes a 360-day year. Trevor's interest is ...
I = $241(0.0194)(54/360) = $0.70

8 Hassan has a jug with a capacity of 800 ml.
He estimates that his bucket holds 20 times that of his jug.
Work out an estimate of the capacity of his bucket.
Give your answer in litres.
Answer:
The capacity of bucket is 16 liters
Step-by-step explanation:
Let j be the quantity of water in the jug
Then
[tex]j = 800ml[/tex]
Let B be the quantity of water held by the bucket
Then t is given that the bucket holds 20 times of water than the jug
[tex]B = 20j[/tex]
Putting the value of j
[tex]B = 800(20) = 16000[/tex]
We also know that
1 liter = 1000 ml
In order to convert ml into liters, we have to divide the quantity by 1000
[tex]B = \frac{16000}{1000} = 16\ liters[/tex]
Hence,
The capacity of bucket is 16 liters

-4x -3 = -19
I'm having trouble with algebra please help.
Answer:
Step-by-step explanation:
-4x - 3 = - 19
Bringing like terms on one side
-4x = - 19 + 3
-4x = - 16
x = - 16/-4
x = 4
Answer:
x=4
Step-by-step explanation:
-4x-3=-19
add -3 to the right side of the equation so -19+3
which will give you -16
then divide by -4
so x=4
find the length of an arc of 40 degrees in a circle with an 8 inch radius.
Answer:
16π/9
Step-by-step explanation:
40°/360° = 1/9
40° is 1/9 of a circle
Arc length = 1/9 of circumference = (1/9)2πr = 16π/9
Nine times the difference of 5 and y
What do you define the circumference of a circle asap!!!
Answer:
to find the circumfrence of a circle you need to do 2 times pi times the radus. the circumfrence of a circle is the outside rim of the circle.

Answer:
Ok, so when you graph, you want to make sure your point are right. 4, would be im guessing +4, so you would find +4, on your graph across the X axis. Keep that in mind. Then find +3, across the Y axis on your graph. Join the points, and you have your answer.

Suppose a normally distributed set of stock prices with 3500 observations has a mean of 101 and a standard deviation of 10. Use the 68-95-99.7 Rule to determine the number of observations in the data set expected to be between the values 91 and 121.
Answer:
The number of observations in the data set expected to be between the values 91 and 121 is of 2853.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 101, Standard deviation = 10
Percentage of of observations in the data set expected to be between the values 91 and 121.
91 = 101 - 10
So 91 is one standard deviation below the mean.
121 = 101 + 2*10
So 121 is two standard deviations above the mean
The normal distribution is symmetric, which means that 50% of the measures are below the mean and 50% are above.
Of those 50% below the mean, 68% are between one standard deviation below the mean(91) and the mean(101).
Of those 50% above the mean, 95% are between the mean(101) and two standard deviations above the mean(121).
So the percentage of observations in this interval is of:
[tex]P = 0.5*0.68 + 0.5*0.95 = 0.815[/tex]
Number of observations in the interval
81.5% of 3500. So
0.815*3500 = 2853
The number of observations in the data set expected to be between the values 91 and 121 is of 2853.
