A. Are the expressions 3(m−2) + 2(m−2) and 5(m−2) equivalent expressions?
B. In two or more complete sentences, justify your answer to A.
Answer: yes, this is because when you solve the first equation then your answer will be 5(m-2). You do this by distributing 3 to m & 2 (multiply), then you will distribute 2 to m & 2 (also multiply).
Step-by-step explanation:
Owen earned some money at a summer job. He saved 1/4 of the money and spent 1/3 of the rest on a t-shirt. He then spent the remaining money on downloading some songs. 1.What fraction of the money did he spend on the downloads?
2. If the t-shirt cost 20$, how much money did Owen earn at the summer job?
He saved 1/4 of the money
3/4 (remaining money lets call it RM)
*answers question 1 * Since he spent 1/3 of the RM on shirt we need to subtract 3/4 (our RM) by 1/3
3/4 - 1/3 = 5/12
the remaining money he spent of downloads is 5/12 of the total money he earned.
He spent 1/3 of the R on a $20 dollar T-shirt, and if $20 is 1/3 of the remaining money then that means that he had 60 dollars he has not saved. (20 x 3 = 60)
*answers question 2* if $60 is 3/4 of the total money he earned then he earned a total of $80 dollars from his summer job.
60/3 = 20
60 + 20 = 80

Rick is setting up a model train track that is 5 5/6
feet long. No telephone pole is needed at the start of the track. However, along the track, he places a telephone pole
every
5/12
foot apart. How many telephone poles does he need? (Input number values only)
Answer:
to understand this we will turn 5 5/6 into a inproper fraction 5 can be turned into 60/12 and 5/6 can be turned into 10/12 so this is equal to 70/12.
5 5/6=70/12
in 70 there are 14 pairs of 5's, 14x5=70
this means that he will need 14 telephone pole's

Triangle BCD With Vertices B(4,4), C(8, 14), And P(12, 0); K = 1/4
Answer:
Hello, I am not sure if you mean a dilation by 1/4. If it is, this will be the answer:
B (1, 1)
C (2, 3.5)
D (3, 0)
Step-by-step explanation:
Just divide each number by 4. B (4, 4) = B (4/4, 4/4) = B (1, 1)
Continue to do this for each coordinate set given.
Hope this helps!
The vertices of triangle B'C'D' are:
B'(-1, -1/2)
C'(0, 2)
D'(1, -3/2)
What is a triangle?A triangle is a 2-D figure with three sides and three angles.
The sum of the angles is 180 degrees.
We can have an obtuse triangle, an acute triangle, or a right triangle.
We have,
To find the vertices of triangle B'C'D', which is a dilation of triangle BCD with center at the origin and a scale factor of 1/4,
We can follow these steps:
Find the coordinates of the centroid of triangle BCD.
The coordinates of the centroid G are:
[tex]x_G = (x_B + x_C + x_D) / 3 = (4 + 8 + 12) / 3 = 8[/tex]
[tex]y_G = (y_B + y_C + y_D) / 3 = (4 + 14 + 0) / 3 = 6[/tex]
Translate triangle BCD so that its centroid is at the origin.
We can do this by subtracting the coordinates of the centroid from the coordinates of each vertex:
B(4, 4) → [tex]B_1(4 - 8, 4 - 6) = B_1(-4, -2)[/tex]
C(8, 14) → [tex]C_1(8 - 8, 14 - 6) = C_1(0, 8)[/tex]
D(12, 0) → [tex]D_1(12 - 8, 0 - 6) = D_1(4, -6)[/tex]
Dilate the translated triangle [tex]B_1C_1D_1[/tex] by a scale factor of 1/4.
To do this, we can multiply the coordinates of each vertex by 1/4:
[tex]B_1[/tex](-4, -2) → B'(-4 x 1/4, -2 x 1/4) = B'(-1, -1/2)
[tex]C_1[/tex](0, 8) → C'(0 x 1/4, 8 x 1/4) = C'(0, 2)
[tex]D_1[/tex](4, -6) → D'(4 x 1/4, -6 x 1/4) = D'(1, -3/2)
Therefore,
The vertices of triangle B'C'D' are:
B'(-1, -1/2)
C'(0, 2)
D'(1, -3/2)

Morgan has an 8 1/2 foot board that must be cut into boards that are feet long. How many of the smaller boards can he get from the 8 1/2 foot board?
Which of the following equations could you use to solve the problem?
x * 8 1/2 = 5/6
8 1/2 * x = 5/6
5/6 * 8 1/2 = x
8 1/2 / 5/6 = x
Answer:
8 1/2 / 5/6 = xStep-by-step explanation:
8 1/2 foot board to be cut into 5/6 feet boards.
Number of smaller boards is:
8 1/2 ÷ 5/6 = 17/2 ÷ 5/6 = 17/2 × 6/5 = 51 / 5 = 10 (the whole part)Correct equation is D
Write an equation representing the relationship of 10:20 shown in the graph
Answer:
[tex]20=2(10)[/tex]
Step-by-step explanation:
10:20 is a good point that passes a line to another.
This graph is a linear graph.
The linear equation is
[tex]y=mx+b[/tex]
[tex]y[/tex] = 20 (the y coordinate in the graph)
[tex]m[/tex] = slope
[tex]x[/tex] = 10 (the x coordinate in the graph)
[tex]b[/tex] = y-intercept
Finding slope
To find the equation, we'll need to plug in the values in the formula. To find slope using two points, use the formula, then plug in the values:
[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
(10, 20) and (20, 40)
[tex]=\frac{40-20}{20-10}[/tex]
[tex]= \frac{20}{10}[/tex]
[tex]\bold{m= 2}[/tex]
Finding the y-intercept
You have to find the slope first before finding the y-intercept. So, plugin one of the two points we used to find the slope into the formula and solve for [tex]b[/tex]
(10, 20)
[tex]20=2(10)+b[/tex]
[tex]20=20+b[/tex]
[tex]20-20=20-20+b[/tex]
[tex]\bold{b=0}[/tex]
The y-intercept is zero, and when it is, you do not add it since zero is nothing.
The equation is [tex]20=2(10)[/tex]
