Answer:
[tex]-4n+\frac{1}{3m}+4n-\frac{4}{5m}=-\frac{7}{15m}[/tex]
Step-by-step explanation:
Given the expression
[tex]-4n\:+\:\frac{1}{3m}\:+\:4n\:-\frac{4}{5m}[/tex]
Group like terms
[tex]-4n\:+\:\frac{1}{3m}\:+\:4n\:-\frac{4}{5m}=-4n+4n+\frac{1}{3m}-\frac{4}{5m}[/tex]
Adding similar elements: -4n + 4n = 0
[tex]=\frac{1}{3m}-\frac{4}{5m}[/tex]
L.C.M of 3m and 5n will be: 15m
so adjusting fractions based on the LCM
[tex]=\frac{5}{15m}-\frac{12}{15m}[/tex]
Since, the denominators are equal, combine the fractions: [tex]\frac{a}{c}\pm \frac{b}{c}=\frac{a\pm \:b}{c}[/tex]
[tex]=\frac{5-12}{15m}[/tex]
[tex]=\frac{-7}{15m}[/tex]
[tex]=-\frac{7}{15m}[/tex]
Therefore, we conclude that:
[tex]-4n+\frac{1}{3m}+4n-\frac{4}{5m}=-\frac{7}{15m}[/tex]

LAST QUESTION ON UNIT TEST!!! PLEASE HELP!!!
A supermarket display consists of boxes of soda. The bottom row has 38 boxes. Each row has four fewer boxes than the row below it. The display has eight rows.
a) Write and use the function to determine how many boxes are in the top row. Show your work.
b) Use the appropriate formula to determine the number of boxes in the entire display. Show your work.
Answer: A=(38*x)-(x*4) (x equals rows)
So the top row consists of 272 boxes of soda.
Web Gamer sells texture packs for video games. They charge an initial $5.50 software set-up fee and $15 for each texture pack purchased through their website. Which equation represents the situation?
Answer:
y=15x+5.50

Which of the following is the radical expression 2d 7/10
Answer:
[tex]2d^{\frac{7}{10}}[/tex] [tex]= \sqrt[10]{2d^7}[/tex]
Step-by-step explanation:
Given
[tex]2d^{\frac{7}{10}}[/tex]
Required
Determine the radical expression
To do this, we apply the following law of indices:
[tex]a^{\frac{m}{n}} = \sqrt[n]{a^m}[/tex]
By comparing the above to [tex]2d^{\frac{7}{10}}[/tex], we have:
[tex]m=7[/tex]
[tex]n = 10[/tex]
So, the solution becomes
[tex]2d^{\frac{7}{10}}[/tex] [tex]= \sqrt[10]{2d^7}[/tex]

Answer:
75 + 64 = 139
Step-by-step explanation:
The measure of the exterior angle is 139
Answer:
2= 139
Step-by-step explanation:
A triangle is 180 degrees.
64+75= 139
180-139=41
A line is also 180 degrees
180- 41= 139
If QS and TƯ
are parallel lines and
m
55°, what is m
Answer:
m is your slope. In parallel lines, your slopes are always the same and the y-intercept is always different. so ur slope is also 55.

Given:
The table shown the number of campers, x, at a local campsite and the total amount of money, y, in dollars, earned by the camp site.
To find:
The unit for the rate of change.
Solution:
We know that, rate of change is the change in y-values with respect to x-values, i.e.,
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
In the given problem, y is the total earnings in dollars and x is the number of campers. So, the rate of change represents the change is earnings with respect to number of campers.
Thus, the unit of rate of change is dollars per camper.
Therefore, the correct option is D.
A furniture store salesman had $15,200 in total monthly sales last month. He made $912 in commission from those sales.
What is the salesman's commission as a percent of his total monthly sales?
Enter your answer in the box.
Answer:
6%
Step-by-step explanation:
percent = part/whole * 100%
percent = 912/15,200 * 100%
percent = 6%

The graph represents function 1 and the equation represents function 2:
A graph with numbers 0 to 4 on the x-axis and y-axis at increments of 1. A horizontal straight line is drawn joining the ordered pairs 0, 3 and 4, 3.
Function 2
y = 3x + 1
How much more is the rate of change of function 2 than the rate of change of function 1? (5 points)
1
2
3
4
Answer:
The rate of change of function 1 = 0The rate of change of the function 2 = 3Therefore, the rate of change of function 2 is 3 more than the rate of change of function 1.
Hence, option C is true.
Step-by-step explanation:
Function 1
A horizontal straight line is drawn joining the ordered pairs (0, 3) and (4, 3).
Given the points
(0, 3)(4, 3)It means
at x = 0, y = 3
at x = 4, y = 3
Since the y-values are same, it means the points lie on a horizontal.
The rate of change or slope of a horizontal line is zero because it does not rise vertically ( i.e. y₁ - y₂ = 0).
Therefore, the rate of change of function 1 = 0
Function 2
y = 3x+1
comparing with the slope-intercept form
y = mx+b
here m is the rate of change or slope and b is the y-intercept
so the rate of change of the function 2 = m = 3
Conclusion:
The rate of change of function 1 = 0The rate of change of the function 2 = 3Therefore, the rate of change of function 2 is 3 more than the rate of change of function 1.
Hence, option C is true.
Diego pours 6.8 ounces of water from a full bottle. He estimates that he poured out 20% of the water in the bottle. About how much water was in the full bottle? Diego pours out 25% of the remaining water. About how many ounces did he pour the second time? Explain your reasoning.
Answer:
34 ounces were in the full bottle , The second time he poured about 7.48 ounces
Step-by-step explanation:
20 times 5 = 100 so,
6.8 times 5 = 34
PART 2
Diego poured out 20% wich is equal to 6.8 and if you subtract both pour's that he did you get 20.4. The you subtract that amount that he had already poured from the total wich gives you 13.6 and 5% of 13.6 is 0.68. Add 0.68 and 6.8 to get 7.48
Simon drove through some roadworks where the speed limit was 50 mph. Two cameras recorded the time taken to travel 1200 m through the roadworks as 56 seconds . Was Simon speeding through the roadworks ?
Answer:
[tex]Speed = 21.43m/s[/tex]
Step-by-step explanation:
Given
[tex]Distance = 1200m[/tex] -- of the roadworks
[tex]Time\ Recorded = 56s[/tex]
Required
Determine the speed
In this case:
[tex]Speed = \frac{Distance\ of\ Roadword}{Time\ Captured}[/tex]
[tex]Speed = \frac{1200m}{56s}[/tex]
[tex]Speed = 21.43m/s[/tex] --- approximated

At a local amusement park 70% of the rides are 48 inches taller if there are 80 rides in total how many are made for kids who are 48 inches and taller?
Answer:
56 rides
Step-by-step explanation:
Total number of rides = 80 rides
If 70% of the rides are 48 inches taller, the total number of rides 70% taller wil be;
Rides 48 inches taller = 70% * 80
Rides 48 inches taller = 0.7 * 80
Rides 48 inches taller = 56
Hence the total rids made for kids that are 48inches taller is 56 rides

Please help is this undefined or 0?
Answer:
0
Step-by-step explanation:
A horizontal line has slope zero since it does not rise vertically (i.e. y1 − y2 = 0), while a vertical line has undefined slope since it does not run horizontally (i.e. x1 − x2 = 0).
Answer:
0
Step-by-step explanation:
Undefined slopes are vertical, this is horizontal
