10x - 19 = 4x + 23
Solve for x
10x - 19 = 4x + 23
-4x -4x
6x - 19 = 23
+19 +19
6x = 42
6 6
x = 7
Plug in x and solve for FE
10x - 19 = 10(7)-19 = 51

Step-by-step explanation:
Finding the height:Greatest common factor (GCF) is the highest number that is a factor of 2 numbers. Not sure if that makes sense.
For example, GCF of 8 and 4 is 4, because 4 is the highest factor that fits into both numbers. 4x2=8 and 4x1=4.
In this case, the height is 7, because that's the GCF of 21 and 70. There's no bigger common factor than that. 7x3=21 and 7x10=70
Finding the length and area:Now that we know the "height", even though there's no such thing as height when calculating the area, we know the length.
The area of something is length x width. Your assignment calls it height for some reason so we'll use height x length.
Area of the 2 shapes is already given, which is 21n for the first shape. Length of the first shape is 3n because 3nx7=21n. Recall that 7 is what we found earlier.
As we can see, the "height" of the 2nd shape is the same as the first, therefore it should also be 7.
Since we are given the area of the 2nd shape, we now know its length. Length of 2nd shape is 10, because 7x10=70.
Evaluate the following: 77 - |( -8)(3) + (-10)(4)|
Answer:
13
Step-by-step explanation:
77−|(−8)(3)+(−10)(4)|
=77−|−24+(−10)(4)|
=77−|−24+−40|
=77−|−64|
=77−64
=13

if log y=3(log 4 + log x), express y in terms of x. serious answers only please no files or nun of that.
Answer:
The expression is [tex]y = 64 + x^{3}[/tex].
Step-by-step explanation:
Let be [tex]\log y = 3\cdot (\log 4 + \log x)[/tex], the "log" component is refered to logarithms with base 10. By definition of logarithm and its properties, we derive an expression of [tex]y[/tex] in terms of [tex]x[/tex]:
[tex]\log y = 3\cdot (\log 4 + \log x)[/tex]
[tex]10^{\log y} = 10^{3\cdot (\log 4 + \log x)}[/tex]
[tex]y = 10^{3\cdot \log 4}+10^{3\cdot \log x}[/tex]
[tex]y = 10^{\log 4^{3}}+10^{\log x^{3}}[/tex]
[tex]y = 64 + x^{3}[/tex]
The expression is [tex]y = 64 + x^{3}[/tex].

A storage shed with a flat roof is 12 feet long by 9 feet wide by 4 1/2 feet tall.
How many cubic feet of storage space does the shed enclose?
Answer:
To get the volume of the shed in yards, multiply 4*3*2.5=30
since one cubic yard is equal to 27 cubic feets, multiply 27 with 30 to get the volume in cubic feets 27*30=810

Math honestly shouldn't exist-
Answer:
This isn't really that hard... ∠A = 166°
Step-by-step explanation:
Because ∠A and ∠B are corresponding angles of a set of parallel lines, that means they are equal, so you can use this equation to solve for x:[tex]7x+40=3x+112[/tex] ⇒ [tex]4x=72[/tex] ⇒ [tex]x=18[/tex]. To find ∠A, just substitute x for 18 and you'll get that ∠A equals 7 * 18 + 40 = 126 + 40 = 166°.

The correct option is,
⇒ get a list of students at her school from the office and use a random number generator to pick 30 of them.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Bella want to know what the students at her school think of her show. which is the BEST group to survey to find this information
Now, For getting accurate results she must select a random sample without bias
For this option a will not serve since she selects only students she recognizes.
Hence, Option B may not be right, as during show on the face they may not give correct opinion
And, Option C is right as a random sample is taken
And, Option D is wrong as the first 30 students may not be at random.
Thus, The correct option is,
⇒ get a list of students at her school from the office and use a random number generator to pick 30 of them.

Answer:
x = 7
y = 25
Step-by-step explanation:
First, we know that x=7 because has the same hypotenuse (the long side) and also has a right angle.
Now, to find out y. The equation for discovering the hypotenuse is:
c = √(a² + b²)
C is the hypotenuse.
A is one of the shorter sides.
B is also one of the shorter sides.
NOTICE: THIS EQUATION ONLY WORKS FOR RIGHT TRIANGLES.
So, now you just need to fill the equation in:
c = √(7² + 24²)
c = √(49 + 576)
c = √(625)
c= 25
So, now we have y, the hypotenuse!
Hope this helped :D

Rewrite without absolute value for the given conditions:
y =|x −3|+|x +2|−|x −5|, if x < −2
Answer:
y = -x - 4
Step-by-step explanation:
y =|x −3|+|x +2|−|x −5|, if x < −2
let x = -1
y1 =|x −3|
y1 = - ( x - 3 ) = -x + 3
y2 = |x +2|
y2 = - (x +2) = -x - 2
y3 = |x −5|
y3 = - (x −5) = -x + 5
y = y1 + y2 + y3
substitute back into original
y = -x + 3 - x - 2 - (-x + 5)
y = -x + 3 - x - 2 + x - 5
y = -x - 4
