Find the student’s error in solving the following inequality.
31 < –5x + 6
25 < –5x
–5 < x
The student should have added 6 to both sides instead of subtracting it.
The student divided 25/–5 incorrectly.
The student should have switched the direction of the inequality sign to get –5> x for a final answer.
Answer:
The student should have switched the direction of the inequality sign to
get –5 > x for a final answer.
Step-by-step explanation:
When multiplying or dividing an inequality by a negative "flip" the inequality sign
The student should have switched the direction of the inequality sign to
get –5 > x for a final answer.

Note:
For a more conventional appearance the entire inequality can be flipped to
–5 < x

A number has a remainder of 1 when divided by 4 a remainder of 2 when divided by 5 and a remainder of 3 when divided by 6. What is the smallest number that has the above properties?
Answer:
Smallest number with the properties in the question = 57
Step-by-step explanation:
Let's first find the LCM of the three numbers which it is divided by which are 4,5,6.
LCM of 4,5 and 6 is 60.
We are told that;
The number has a remainder of 1 when divided by 4
The number has a remainder of 2 when divided by 5
The number has a remainder of 3 when divided by 6
In all 3 cases, the difference between the divisor and the remainder is 3.
This means that the smallest number in that has the properties in the question must be; 60 - 3 = 57

Convert the equation x2 + 4y2 + 2x + 24y + 21 = 0 into standard form.
Answer:
(X+1)²+4(y+3)² = (√-20)²
Step-by-step explanation:
The standard form of expressing equation ic;
(x-a)²+(y-b)² = r²
Given the expression
x²+4y²+2x+24y+21 = 0
Collect the like terms
x²+2x + 4y²+24y+21 = 0
Completing the squares
x²+2x +(2/2)² + 4(y²+6y)+21 = 0+(2/2)²
x²+2x +(2/2)² + 4(y²+6y+(6/2)²)+21 = 0+(2/2)²
x²+2x +1 + 4(y²+6y+(3)²)+21 = 0+1
x²+2x +1 + 4(y²+6y+9)+21 = 0+1
x²+2x +1 + 4y²+24y+36+21 = 0+1
x²+2x +1 + 4(y²+6y+9)+21 = 0+1
x²+2x +1 + 4(y+3)²+21 = 0+1
(X+1)²+4(y+3)² = 1 - 21
(X+1)²+4(y+3)² = -20
(X+1)²+4(y+3)² = (√-20)²

C. Length
D. Width
Answer:
Length and Width
Step-by-step explanation:
I took the A P E X quiz
A polygon's measurement includes Length and Width, That is option c and d.
What is Polygon?
A Polygon is a closed figure made up of lines segments (not curves) in two-dimensions. A minimum of three line segments are required for making a closed figure, thus a polygon with a minimum of three sides is known as Triangle.
Polygon has a plain 2D shape which has minimum 3 sides.
polygon not has curve lines.
Polygon is not 3D shape figure, so height is not a measurement of polygon.
Hence, Length and Width is the measurement of polygon

Answer:
15
Step-by-step explanation:
4 x __ = 12
the blank would be 3, once you did it on one side you have to do it on the other side too
5 x 3 = 15
Another way you can do it is by...
[tex]\frac{4}{12}[/tex] = [tex]\frac{5}{x}[/tex]
solve for x (cross multiply)
Answer:
15
Step-by-step explanation:
CO : CL = OR : LA
* substitute the side letters with the given side lengths *
( let AL = x )
4 : 5 = 12 : x or
[tex]\frac{4}{5} =\frac{12}{x}[/tex]
now we solve for x by cross multiplying
4 * x = 4x
12 * 5 = 60
now we have 4x = 60
step 2 divide each side by 4
4x / 4 = x
60 / 4 = 15
we're left with x = 15
hence LA = 15

All square roots can be simplified to a decimal answer and still be equivalent.
THE ANSWER IS TRUE :P
Step-by-step explanation:
All the square roots can be simplified to a decimal answer and still be equivalent.
What is Square Root?Square root of a number is the value such that the value when multiplied to itself two times gives the original number.
It is denoted by the symbol √.
For example, square root of 16 is 4 since 4 × 4 = 16
We know that every number has a square root.
All the numbers does not have a perfect square root.
The perfect square roots does exists for numbers 1, 4, 9, 16, 25, .......
All the other numbers in between has the square roots which are decimal numbers.

To find:
The quotient of [tex]1.888\times 10^9[/tex] and [tex]5.9\times 10^6[/tex] expressed in scientific notation.
Solution:
Quotient of [tex]1.888\times 10^9[/tex] and [tex]5.9\times 10^6[/tex] is:
[tex]\dfrac{1.888\times 10^9}{5.9\times 10^6}=\dfrac{1.888}{5.9}\times \dfrac{10^9}{10^6}[/tex]
[tex]\dfrac{1.888\times 10^9}{5.9\times 10^6}=0.32\times 10^{9-6}[/tex]
[tex]\dfrac{1.888\times 10^9}{5.9\times 10^6}=0.32\times 10^{3}[/tex]
In the scientific notation, the first number is between 1 to 10. So, 0.32 can be written as [tex]\dfrac{3.2}{10}[/tex].
[tex]\dfrac{1.888\times 10^9}{5.9\times 10^6}=\dfrac{3.2}{10}\times 10^{3}[/tex]

Which representation shows y as a function of x?
A line passes through the points (0, 7) and (2, 3). Given this information, complete the equation below (y= mx+b) by determine the slope and y-intercept.
Answer:
y = -2x + 7
Step-by-step explanation:
Given: (0, 7) and (2, 3)
Using the slope-intercept formula: y2-y1/x2-x1
3-7/2-0 = -4/2 = -2
Y-intercept:
Use y= mx + b to find the y-intercept (b). For this, I will be using the coordinates (2, 3). Plug 2 into x and 3 into y, then solve.
3 = -2(2) + b
3 = -4 + b
7 = b
Form the equation together:
y = -2x + 7
Rewrite the equation in Ax+By=C form.
Use integers for A, B, and C.
y + 2 = 6(x+6)
Given:
The equation is:
[tex]y+2=6(x+6)[/tex]
To find:
The given equation in the form of [tex]Ax+By=C[/tex], where A, B, C are integers.
Solution:
We have,
[tex]y+2=6(x+6)[/tex]
It can be rewritten as:
[tex]y+2=6x+36[/tex]
[tex]y-6x=36-2[/tex]
[tex]-6x+y=34[/tex]
The above equation is in the form of [tex]Ax+By=C[/tex], where [tex]A=-6,B=1[/tex] and [tex]C=34[/tex].
Therefore, the requires equation is [tex]-6x+y=34[/tex].
