Here is your equation:
[tex]6 \frac{7}{8} + 7 \frac{5}{12}[/tex]
As you can see, the denominators, which is the bottom number in the fraction, are different. You need to have the same denominator, so that you can add it. To change the denominators, you need to find the LCM of both denominators, which is 8 and 12. To find the LCM, first list the multiples of both numbers and see what is common.
[tex]8 - 8, 16, 24, 32, 40, 48, 56 \\12-12, 24, 36, 48[/tex]
The only common number is 48. That means you need to change both fractions so that they have a denominator of 48.
[tex]6 \frac{7 \times 6}{8 \times 6} \rightarrow 6 \frac{49}{48}[/tex]
[tex]7 \frac{5 \times 4}{12 \times 4} \rightarrow 7 \frac{20}{48}[/tex]
Here is your new equation:
[tex]6 \frac{49}{56} + 7 \frac{20}{48}[/tex]
Add:
[tex]6 \frac{49}{48} + 7 \frac{20}{48} = 13 \frac{69}{48}[/tex]
Simplify:
[tex]13 \frac{69}{48} \rightarrow 14 \frac{21}{48} \rightarrow 14 \frac{7}{16}[/tex]
Your answer is 14 [tex]\frac{7}{16}[/tex]

(w+14)/(4w+6)=(3)/(4) show work plz
Answer:
w = -1.44 and w = -14.06
Step-by-step explanation:
That "(3) / (4)" in (w+14)/(4w+6)=(3)/(4) looks fishy. Assuming that you really meant 3/4, then we have (w+14)/(4w+6)=3/4.
Mult. both sides by 4 to remove the fraction: 4(w+14)/(4w+6) = 3.
Multiply out (w+14)/(4w+6): 4w^2 + 6w + 56w + 84. Combine the w terms, obtaining 4w^2 + 62w + 84. Then the original equation becomes:
4w^2 + 62w + 84 = 3, or 4w^2 + 62w + 81 = 0.
This is a quadratic equation, with a = 4, b = 62 and c = 81. The two roots (values of
w) are as follows:
-62 plus or minus √(62^2-4(4)(81)
----------------------------------------------------------
8
-62 plus or minus √(2548) -62 plus or minus 50.48
w = ------------------------------------------- = ---------------------------------------
8 8
Simplifying, we get w = -1.44 and w = -14.06
To solve the algebraic equation (w+14)/(4w+6) = 3/4, we clear the fractions, combine like terms, and isolate the variable w, which gives us the solution w = 4.75.
To solve the equation (w+14)/(4w+6) = 3/4, we first clear the fractions by multiplying both sides by the least common denominator, which is 4(4w+6). This eliminates the denominators and gives us:
4(w + 14) = 3(4w + 6)
Distribute the 4 on the left side and the 3 on the right side:
4w + 56 = 12w + 18
Next, we want to get all the terms with w on one side and the constant terms on the other. Subtract 4w and 18 from both sides:
4w + 56 - 4w - 18 = 12w + 18 - 4w - 18
This simplifies to:
38 = 8w
Divide both sides by 8 to isolate w:
w = 38 / 8
Finally, simplify the fraction to find the value of w:
w = 4.75

Is the equations true, false, open or none of the above?
10x + 5 = 8x + 2
10x + 5 = 8x + 2
Subtract 5 from both sides.
10x = 8x - 3
Subtract 8x from both sides.
2x = -3
Subtract both sides by 2.
x = -1.5
Because we are able to get a value for x, we know that the equation is true, as we can plug the value of x back into the original equation to verify.
10(-1.5) + 5 = 8(-1.5) + 2
-15 + 5 = -12 + 2
-10 = -10 √ this equation is true.
For the equation 10x + 5 = 8x + 2, the statement is true.
The given equation is 10x + 5 = 8x + 2.
The first thing to do is to subtract 5 from both sides.
10x + 5 - 5 = 8x + 2 - 5
10x = 8x - 3
Then, we'll subtract 8x and this will be:
10x - 8x = -3
2x = -3
Divide both side by 2
2x/2 = -3/2
x = -1.5
10x + 5 = 8x + 2,
10(-1.5) + 5 = 8(-1.5) + 2
-15 + 5 = -12 + 2
10 = 10

You are packaging expansion packs for the game of checkers. The table below lists the number of each part needed per expansion pack, as well as the number of each part that you have available.
Part Number in each pack Number available
People marker 6 287
6-sided die 3 143
Teleporter marker 7 341
You make as many expansion packs as you can. With the parts remaining, you could make 1 more expansion pack if you had:
A) 1 more people marker and 1 more die.
B) 1 more die and 1 more teleporter marker.
C) 1 more teleporter marker and 1 more people marker.
D) 2 more people markers.
E) 2 more teleporter markers
Answer: Option (A)1 more people marker and 1 more die.
Step-by-step explanation:
We have to pack expansion packs for the game of checkers in such a way such that there should be enough cards as per requirement.
So for that we have to find packs of each item by dividing each pack by part numbers and what is left after as remainder.
People marker =287 =6(47) + 5 ( as each pack of people marker contains 6 items)
6-sided die =143 = 3(47) + 2 (as each pack of 6- sided die contains 3 items)
Teleport-er marker=341 = 7(48) + 5 (as each pack contains 7 teleport-er marker)
So we can see that for 48th pack we have enough Teleport-er marker just we need one People marker and one 6-sided die. which is option A.
Given the quantities of game components available, we can form 47 complete expansion packs. We can form another pack if we had 1 more 6-sided die and 1 more people marker. Thus, the correct answer is option A.
Explanation:To answer the question, we first need to calculate how many complete expansion packs can be made with the available components:
People marker: We would divide the total number of available markers (287) by the number needed for each pack (6). Thus, a total of 47 full packs can be made with an extra 5 markers left over. 6-sided die: Dividing the total number of dice available (143) by the number needed for each pack (3), we get 47 full packs with 2 dice left over. Teleporter marker: Divided by 7 (the amount needed per pack), the 341 available teleporter markers would result in 48 full packs with 5 markers left over.
Given the available quantities, we can make a total of 47 complete packs. However, we'd have enough components to complete one more pack if we had 1 more die and 1 more people marker. Therefore, the correct answer is option A.

Multiply both sides by 3.
42 = 2x
Divide both sides by 2.
21 = x
The value of x is equal to 21.
The equation, twelve is the same as two-thirds a number diminished by two - True
Explanation:To determine if twelve is the same as two-thirds of a number diminished by two, we can set up an equation. Let's represent the number as 'x.' According to the statement, twelve is equal to two-thirds of x diminished by two. Mathematically, this can be written as:
12 = (2/3)x - 2
To solve for x, we need to isolate it on one side of the equation. First, we can add 2 to both sides:
14 = (2/3)x
Next, we can multiply both sides by 3/2 to eliminate the fraction:
14 * (3/2) = x
21 = x
Therefore, the number in question is 21. To confirm, we can substitute x back into the original equation:
12 = (2/3)(21) - 2
12 = 14 - 2
12 = 12
Since the equation is true, we can conclude that the statement is True.

Audrey is trying to find the equation of a line parallel to y = 2 over 3 x −5 in slope-intercept form that passes through the point (−6, −1). Which of the following equations will she use
Final answer:
To find the parallel line's equation, Audrey used the slope of 2/3 from the given line and the point (-6, -1) to write the equation in point-slope form, eventually simplifying it to y = 2/3x + 3.
Explanation:
Audrey is looking to find the equation of a line that is parallel to the line with the equation y = 2/3x - 5 and that passes through the point (-6, -1). Since parallel lines have the same slope, our new line will keep the slope of 2/3. Using the point-slope form of the equation of a line, we set up y - y1 = m(x - x1). Plugging in the known slope m and point (x1, y1), we get y - (-1) = 2/3(x - (-6)). After simplifying, we have y + 1 = 2/3x + 4. Finally, we solve for y by subtracting 1 from both sides, yielding the equation y = 2/3x + 3 as the line that is parallel to the original line and passes through the given point.

Part A:
Write an equation that can be used to model this situation.
Part B:
Solve the equation and interpret the solution in terms of the context, determining if the solution is viable.
Answer:
(a)[tex]5n=3n+15[/tex]

Solution is not viable
Step-by-step explanation:
(a)
Total number of red ping pong balls[tex]=5[/tex]
Total number of red ping pong balls[tex]=n[/tex]
Now, probability of an event [tex]=\frac{Number of favourable events}{Total number of events}[/tex]
Then, theprobability of randomly choosing a blue ping pong ball is
[tex]=\frac{n}{n+5}[/tex]
Given that this probability is[tex]=\frac{3}{5}[/tex]
Thus, we have that,
[tex]\frac{n}{n+5}= \frac{3}{5}\\ 5n=3(n+5)\\5n=3n+15[/tex]

Solving, the above equation,
[tex]5n=3n+15\\2n=15\\n=7.5[/tex]
This solution is not viable as, number of ping pong ball must be an integer and not a decimal number.
Graph the image of this figure after a dilation with a scale factor of 2 centered at (2, 2) .
Use the polygon tool to graph the dilated figure.
Answer:
The points of the dilated figure would be at (-2, 10), (2, 6), and (-8, 4); an image of the figure is attached.
Step-by-step explanation:
First we translate the center of dilation and figure so the origin becomes the center of dilation.
Since the point (2, 2) is our center of dilation, we must translate it left 2 and down 2 to make the origin the center; this means we map every point
(x, y)→(x-2, y-2)
The scale factor of 2 means that each point will be multiplied by 2; this gives us the rule
(x, y)→(2x-4, 2y-4)
Lastly we will translate the figure right 2 and up 2 to move it back to its original position; this gives us the rule
(x,y)→(2x-4+2, 2y-4+2) = (2x-2, 2y-2)
The first point in the original figure, at the top, is (0, 6). Applying the transformation gives us
(0, 6)→(2*0-2, 2*6-2) = (0-2, 12-2) = (-2, 10)
The point on the right of the pre-image is (2, 4). Applying the transformation rule gives us
(2, 4)→(2*2-2, 2*4-2) = (4-2, 8-2) = (2, 6)
The point on the left of the pre-image is at (-3, 3). Applying the transformation rule, we have
(-3, 3)→(-3*2-2, 3*2-2) = (-6-2, 6-2) = (-8, 4)

D(2, –4) → D' = (-4, 2)
E(1, –1) → E'= (-1, 1)
F(5, 1) → F'=(1, 5)
What is the rule that describes a reflection across the line y = x?
rx = y(x, y)= (y, x)
The rule which describes a reflection across the line is y(x, y) --> (y, x) and the mapping of the vertices of ΔDEF is (-4, 2)D', (-1, 1)E' , (1, 5)F'.
What is reflection?The reflection of a plane or shape is flipping the original figure with respect to a reference line.
The following steps are used to for reflecting a shape-
Select the shape which has to be reflected.Select a base line or reference line over which the shape has to be reflected.Mark the corners of the shape at the equidistant from the reference line as the original shape has, but in the opposite direction.The reflected shape is now is facing the opposite direction.The rule that describes a reflection across the line says that when your reflect a point across the line say y=x. Then the coordinates of x and y are interchanged as,
y(x, y) → (y, x)
Now let's complete the mapping of the vertices of ΔDEF using the above rule. For this, change the places of x and y coordinate as,
D(2, –4) → (-4, 2)D'
E(1, –1) → (-1, 1)E'
F(5, 1) → (1, 5)F'
Thus, the rule which describes a reflection across the line is y(x, y) --> (y, x) and the mapping of the vertices of ΔDEF is (-4, 2)D', (-1, 1)E' , (1, 5)F'.

Jeremy surveyed students in his class about their spending habits in the school cafeteria. He used the data to create a scatterplot.
Answer:
Step-by-step explanation:
From the graph, you can first see that there is a positive slope, and a negative y intercept. That should automatically rule out the first option.next, find the slop...
To do this take the two points that are given (2,5.5) and (5,15.25) and do rise over run. This would be (15.25-5.5)/(5-2). I just put this in a calculator and found the slope to be 3.25. You automatically know the answer because the only equation with the slope 3.25 is the third one.
The scatterplot shows the distribution of the students' spending habit
The equation of the trend line is: [tex]\mathbf{y = 3.25x -1}[/tex]
From the scatter plot (see attachment), we have the following points:
[tex]\mathbf{(x,y) = (2,5.5)\ (5,15.25)}[/tex]
So, the slope (m) of the trend line is:
[tex]\mathbf{m = \frac{y_2 - y_1}{x_2 - x_1}}[/tex]
This gives
[tex]\mathbf{m = \frac{15.25 - 5.5}{5- 2}}[/tex]
[tex]\mathbf{m = \frac{9.75}{3}}[/tex]
[tex]\mathbf{m = 3.25}[/tex]
The equation of the trend line is then calculated as:
[tex]\mathbf{y = m(x - x_1) + y_1}[/tex]
This gives
[tex]\mathbf{y = 3.25(x - 2) + 5.5}[/tex]
[tex]\mathbf{y = 3.25x - 6.5 + 5.5}[/tex]
[tex]\mathbf{y = 3.25x -1}[/tex]
Hence, the equation of the trend line is: [tex]\mathbf{y = 3.25x -1}[/tex]
