We can substitute a definition of one of the variables by rearranging the first equation.
We set the first equation equal to one of our two variables.
[tex]y = 24 - x[/tex]
Now we substitute this equality into our second equation
[tex]3x + 5(24 - x) = 100[/tex]

an square has an area of 54 sq in . the length of each side is the same but not a whole number
Answer:
Answer = 13.5
Step-by-step explanation:
A square has 4 sides
54 / 4 = 13.5
The side of the square will be 7.34 inches.
What is an area?A square is a quadrilateral having all the sides equal to each other and the sum of the angles will be 360 degrees. The area is defined as the space occupied by the shape in a two-dimensional plane.
Given that a square has an area of 54 sq in . the length of each side is the same.
The side of the square will be calculated as below:-
Area of square = Side²
54 = Side²
Side = √54
Side = 7.34 inches.
Therefore, the side of the square will be 7.34 inches.

B. None of these
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

Solve for x in the diagram below.
Answer:
x = 9
Step-by-step explanation:
The parallel lines divide the sides of the triangle in proportion, that is
[tex]\frac{20-8}{x}[/tex] = [tex]\frac{8}{6}[/tex]
[tex]\frac{12}{x}[/tex] = [tex]\frac{8}{6}[/tex] ( cross- multiply )
8x = 72 ( divide both sides by 8 )
x = 9
What is the quotient of 1.888\times 10^91.888×10 9 and 5.9 \times 10^65.9×10 6 expressed in scientific notation?
Given:
The expressions are [tex]1.888\times 10^9[/tex] and [tex]5.9\times 10^6[/tex].
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]
[tex]\dfrac{1.888\times 10^9}{5.9\times 10^6}=3.2\times 10^{3-1}[/tex]
[tex]\dfrac{1.888\times 10^9}{5.9\times 10^6}=3.2\times 10^{2}[/tex]
Therefore, the value of the quotient is [tex]3.2\times 10^{2}[/tex].
A butcher purchases 50 chicks at the rate of Ts.60 per chick.10 of them died and he sold remaining chicks at the rate of Rs.80 per chick. Find profit or loss percentage.
Answer: 6.25%
Step-by-step explanation:
50 chicks were purchased at Rs. 60. The total cost of the chicks is:
= 50 * 60
= Rs. 3,000
10 of the chicks died which means the farmer was left with 40 chicks.
These chicks are sold at Rs. 80. Total revenue from the sales are:
= 40 chicks * 80
= Rs. 3,200
The profit is:
= 3,200 - 3,000
= Rs. 200
The percentage is:
= Profit / Revenue
= 200 / 3,200
= 6.25%

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].

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
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

Right triangle ABC is shown. Triangle A B C is shown. Angle A C B is a right angle and angle C B A is 50 degrees. The length of A C is 3 meters, the length of C B is a, and the length of hypotenuse A B is c.
Question:
Obtian the equation that can be used to solve for c
Answer:
Sin50 = 3/c
Step-by-step explanation:
A triangle showing the information given has been attached below for clarity :
Using trigonometry :
AC = 3 = opposite side of angle 50°
AB = c = hypotenus
Using the sine relation of a right angled triangle :
Sin θ = opposite / hypotenus
θ = 50°
Sin 50° = 3 / c
Sin50 = 3/c

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
1. Round 9.39 to the nearest whole number
2. what is the value of the expression 4^3+9 times 6
Answer:
Step-by-step explanation:
1. The digits 39 are less than 50. Round 9.39 to 9 (nearest whole number).
2. 4^3+9 times 6 This is an order-of-operations problem. We must do exponentiation before multiplication and division, and addition and subtraction must follow multiplication and division.
4^3 = 64, so we have 64 + 9(6).
Must do multiplication before addition: 64 + 54 = 118

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.
Hence, all square roots can be simplified to a decimal answer and still be equivalent.
