Answer:
The value of x = 18
Step-by-step explanation:
Given the data set
[tex]12,15,x,19,28[/tex]
Given that the median of the data is 18.We know that the median is the middle number in a data set when the data points are in ascending order.As the given data is already in ascending order.
Please observe that the data set has an odd number of data points, meaning that the middle number is the median of the data is 18.As 'x' is the middle number, thus it represents the median value.
Therefore, the value of x = 18
(5x – 3 – x²) + (8x^2– 1+x)
Answer:
7x^2+6x-4
Step-by-step explanation:
(-x^2+5x-3)+(8x^2+x-1)
Just combine like terms.
-x^2+8x^2= 7x
5x+x= 6x

A line that includes the point (1, 1) has a slope of 4. What is its equation in slope-intercept
form?
Answer: y=4x-3
Step-by-step explanation:
point slope form is y-y1=m(x-x1)
y-1=(4)(x-1)
y-1=4x-4
y=4x-3
A messenger entered a building on the ground
(0) floor. He delivered a package to someone on
the 15th floor. That person sent him with a
package to the 3rd floor, who then sent him up
to the 38th floor before finally riding the
elevator all the way back down to the ground
floor to exit. In all, how many floors did the
messenger travel?
The messenger traveled a total of 100 floors while delivering packages.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, A messenger entered a building on the ground floor zero.
He delivered a package to someone on the 15th floor which is (0 + 15).
= 15 floors.
That person sent him with a package to the 3rd floor, which is (15 - 3) = 12 floors.
∴ Total floors he traveled (15 + 12) = 27 floors.
who then sent him up to the 38th floor, so from 3rd to 38th he traveled
(38 - 3) = 35 floors.
∴ Total distance he traveled is = (27 + 35) = 62 floors.
Now he is on the 38th floor so, to reach zero level he needs to travel 38 floors.
Total distance traveled by him is = (62 + 38) = 100 floors.

This question is incomplete
Complete Question
A baker uses 5.5 Ibs of flour daily
The baker's recipe for a loaf of bread calls for 12 oz of flour. If he uses all of his flour to make loaves of bread, how many loaves can he bake in seven days?
Answer:
51.3 loaves of bread
Step-by-step explanation:
Converting 5.5 Ibs to oz (ounces)
1 Ibs =>12 oz
5.5 Ibs => x
Cross Multiply
12 × 5.5 => 88 oz
1 loaf of bread =>12 oz
Hence, in 1 day
12 oz =>1 loaf of bread
88 oz => x
x =>88 oz/ 12 oz
x => 7.3333333333 loaves of bread
Hence, he can make 7.3333333333 loaves of bread in 1 day
Hence, in 7 days
1 day => 7.3333333333 loaves
7 days => x
x => 7 × 7.3333333333 loaves
x => 51.333333333 loaves of bread
Approximately => 51.3 loaves of bread

Nice! Quadratic Equations!
Step-by-step explanation:
Okay, I'll try to keep it as brief as possible.
To find out how many solutions there are in a quadratic equation, we need to find the Discriminate.
It's pretty simple. The form of a quadratic equation is:
[tex]ax^2+bx+c=0[/tex]
Our Discriminant is [tex]b^2-4ac[/tex].
Time to solve! (input b=7, a=9, and c=-4)
[tex]49+144\\193[/tex]
The discriminate is positive, meaning there are two answers.
If it was zero, there would be only one.
if it was negative, there would be no solutions.
Time to actually solve!
Completing the square looks to be a bad solution, so I'll go with the Quadratic Equation. Remember, don't use it too often.
(Quadratic Equation: [tex]x=\frac{-b+-\sqrt{b^2-4ac} }{2a}[/tex])
[tex]x=\frac{-7+-\sqrt{49+144} }{18}[/tex]
[tex]x=\frac{-7+-\sqrt{193} }{18}[/tex] <-------SOLUTION! COME HERE!
193 seems to be a prime number, so I can't simplify it any more.
There's your solution!
(Note: +- means plus/minus, where there are two cases, one where the square root has a negative sign, and the other with a positive sign.)
Happy Quadraticing!

The price of a visit to the dentist is $50 . If the dentist fills any cavities, an additional charge of, 100$ per cavity gets added to the bill.
If the dentist finds cavities, what will the cost of the visit be?
Write your answer as an expression.
Answer:
50+100x=?
Step-by-step explanation:
50 is the amount of money it is for a visit and the x represents how many cavities are being filled and the 100 is for how much it is per cavity to be filled. For example if you needed 3 cavities filled then it would be 50+(100x3).
