Find the value of each variable.
2(5x − 5)°
20yº
(5y + 5)
(3x - 5)°
Answer:
The answer is 10 for your math equation
Step-by-step explanation:
The values of each variable are x = 15° and y = 7°.
Given are two lines, intersecting each other at a point to make angles,
2(5x − 5)°, 20y°, (5y + 5)° and (3x - 5)°.
We need to find the values of the variables.
The lines are intersected in such a way that the angles 2(5x − 5)°, (3x - 5)°and (5y + 5)°, 20y° are making linear pairs.
We know that the linear pair angles sum up to make 180°.
So,
2(5x − 5)° + (3x - 5)° = 180°
10x - 10 + 3x - 5 = 180°
13x - 15 = 180°
13x = 195°
x = 15°
Similarly,
(5y + 5)° + 20y° = 180°
5y + 5 + 20y = 180°
25y = 175°
y = 7°
Hence the values of each variable are x = 15° and y = 7°.

Step-by-step explanation:
Your revenue (in dollars) for selling x bracelets is given by f(x) = 5x and your profit is $50 less than 80% of the revenue. What is your profit for 77 sales?
From the calculation carried out below, it can be observed that the profit for 77 sales is $258.
How do we calculate profit for sales?Given revenue as:
f(x) = 5x ............................ (1)
Where:
x = Number of bracelets sold or sales = 77
Total obtain the revenue, substitute x = 77 into equation (1), we have:
Revenue = f(77) = 5 * 77
Revenue = $385
Since profit is $50 less than 80% of the revenue, we have:
Profit = (Revenue * 80%) - 50
Profit = (385 * 80%) - 50
Profit = 308 - 50
Profit = $258

A pound of rice crackers cost 42.88 jacob purchased 1/4 pound how much did he pay
So you know that a pound of rice crackers cost $42.88. You also know that Jacob bought 1/4 or 25% or 0.25 of a pound. This means that by multiplying 0.25 by $42.88, you can determine the cost.
0.25 x 42.88 = 10.72
Therefore, Jacob paid 10.72 cents or $10.72 for 1/4 pound of rice crackers
If M (-2, 5) is the midpoint of
CD and the coordinates of C are (4, 7), what are the coordinates of D?
Answer:
soln ,given,
midpoint of CD=M(-2,5)
let,
C(4,7)=(x1,y1)
D(x1,y2)=?
now by using midpoint formula =(x1+x2)/2+(y1+y2)/2
M(-2,5)=( 4+x2)/2+(7+y2)/2
comparing both sides
-2=(4+x2)/2
-4=4+x2
-4-4=x2
threfore,x2= -8
again
5=(7+y2)/2
10=7+y2
therefore,y2=3
thus , the coordinate of D is D(-8,3)
A cylindrical can has a radius of 4 centimeters. Write the volume V of the can as a function of the height h.
The volume of cylinder V as a function of the height h is: V = 50.24h
In this question, we have been given the radius of the cylinder which is 4 centimeters.
We need to write the volume V of the can as a function of the height h.
We know that, the formula of volume of the cylinder of radius r and height h is, V = π × r² × h
In this question, r = 4 centimeters
Substitute r = 4 in above formula of volume of cylinder.
⇒ V = π × r² × h
⇒ V = π × 4² × h
⇒ V = 3.14 × 16 × h
⇒ V = 50.24 × h
⇒ V = 50.24h
Therefore, the volume of cylinder V as a function of the height h is:
V = 50.24h

Graph The Lines (Algebra 1)
Answer:
See the picture below
Step-by-step explanation:
Your equations are in the slope-intercept form of a line. The equations are make up of a slope and a y-intercept.
y = mx + b The m is the slope (the steepness of the line) and b is the y-intercept. This is where the line crosses the y axis.
I would start with the y intercept. Look at the first equation
y = x -8 The -8 tells us that this graph crosses the y axis at (0,-8) From that point, we will use the slope. The slope is the number before the x. If we do not see a number than it is 1. We want to make this a fraction. What is 1 as a fraction? 1/1 This means that from -8 where the graph crosses the y axis we will follow the pattern of up one, one to the right.
Let's look at the second graph
y = -x + 5. This tells us that we cross the y axis at (0,5). Our slope is -1. What is -1 as a fraction? -1/1. This means that we will move down 1 and right one. We will follow that pattern.
Let's look at the third graph
y = 3/4x - 1 We cross the y axis at (0,-1) From that point we move up 3 and right 4.
y = 3 means that no matter what x is, y will be -3. This creates a horizontal line.
x = -4 means that not matter what y is, x will be -4. This creates a vertical line.
Evaluate the function.

The dimensions of a square are altered so that one dimension is increased by 7 feet, while the other is decreased by 2 feet. The area of the resulting rectangle is 90 ft2. Find the original area of the square.
Answer:
64 ft^2
Step-by-step explanation:
It is a square to start, so each side = x
then (x+7 ) * ( x -2) = 90
x^2 + 5x -14 = 90
x^2 + 5x - 104 = 0 factor or use Quadratic Formula to fin x = 8 ft
Original area is then 8 x 8 = 64 ft^2

Using the segment addition postulate and the bisection concept, the segment EF bisecting RS is given at the end of the answer.
What is the segment addition postulate?The segment addition postulate is a geometry axiom that states that a line segment, divided into a number of smaller segments, has the length given by the sum of the lengths of the segments.
From this, the bisection concept is derived, which is when a line crosses a segment exactly at the segment's midpoint, meaning that point A is the midpoint of RS.

The solution region for the given pair of inequalities is found to be the common shaded region in the graph attached.
What is inequality?An inequality is a relation which makes a non-equal comparison between two numbers or mathematical expressions.
here, we have,
For drawing the graph of any inequality, we first have to assume the inequality as an equation and draw the graph of the resulting equation. Hence, finding the points for the inequality , we let the inequality as:
Putting y=0, we get:
The point will be: (-2,0)
Now, putting x=0, we get:
The point will be: (0,4)
Now as the sign of inequality is >, the line of graph will be dotted.
Taking a test point (0,0) to find the shaded region, substituting this in the inequality,
So, the shaded region will be away from the test point.
Similarly, finding the points for the inequality , we let the inequality as:
Putting y=0, we get:
The point will be: (6,0)
Now, putting x=0, we get:
The point will be: (0,6)
Now, as the sign of inequality is of , the line of graph will be solid.
Taking a test point (0,0) to find the shaded region, substituting this in the inequality,
So, the shaded region will be towards the test point.
The resulting graph is attached after the solution.
The solution to the pair of given inequalities will be the shaded region that is common between both the individual inequality's shaded regions.

Which of the following is equivalent to (3a + 5b) + 7c?
3a + (5b + 7c)
3a(5b + 7c)
7c(5b + 3a)
8ab + 7c
Answer:
3a + (5b + 7c)
Step-by-step explanation:
The answer cannot be 3a(5b +7c) because when the number is immediately before the brackets, it signifies multiplication. therefore the 3a(5b+7c) would be equivalent to 15ab+21ac
the answer cant be 7c(5b+3a) because of the same explanation as the one above, therefore 7c(5b+3a) would be equivalent to 35cb+21ca
the answer finally cant be 8ab+7c because it means that one added 3a and 5b giving you 8 but it cannot be ab because ab is equivalent to a×b, hence, one cant put a multiplied algebraic expression with an added number
The equation equivalent to the the expression (3a + 5b) + 7c is 3a + (5b+7c). Hence, the first option is the correct one.

For instance, the equation x + y has the terms x and y with an addition operator in between. Numerical expressions, which just contain numbers, and algebraic expressions, which also include variables, are the two types of expressions used in mathematics.
The first option is correct because it does not affect the main equation rest are not the same as the equation.
For example, let's take the second equation :
