Solve the equation using multiplication or division
-13 = m/ -5
A m=13/5
B m=45
C m=65
D m= 5/13
Answer:
1. Solve the equation using addition or subtraction.
[tex]4=q+13[/tex]
Taking like terms on one side, we get
[tex]4-13=q[/tex]
=> [tex]-9=q[/tex]
or [tex]q=-9[/tex] (option C)
2. Solve the equation using addition or subtraction.
[tex]5.5= -2+d[/tex]
Taking like terms on one side, we get
[tex]5.5+2=d[/tex]
So, [tex]d=7.5[/tex] (option B)
3. Solve the equation using multiplication or division
[tex]-7y=28[/tex]
Dividing both sides by 7, we get
[tex]-y=4[/tex]
or [tex]y=-4[/tex] (option A)
4. Solve the equation using multiplication or division
[tex]-13=\frac{m}{-5}[/tex]
Cross multiplying -13 and -5 to get the value of m
[tex]m=(-13)(-5)[/tex]
[tex]m= 65[/tex] (option C)
The solutions of the equations are =
1) C) q = -9.
2) B) d = 7.5.
3) A) y = -4.
4) C) m = 65.
Given are the equation we need to solve them,
Let's solve the equations one by one:
1) 4 = q + 13
To isolate q, we can subtract 13 from both sides of the equation:
4 - 13 = q + 13 - 13
-9 = q
Therefore, q = -9.
The correct answer is C) q = -9.
2)5.5 = -2 + d
To isolate d, we can subtract -2 from both sides of the equation:
5.5 - (-2) = -2 + d - (-2)
5.5 + 2 = d
7.5 = d
Therefore, d = 7.5.
The correct answer is B) d = 7.5.
3) -7y = 28
To solve for y, we can divide both sides of the equation by -7:
(-7y) / (-7) = 28 / (-7)
y = -4
Therefore, y = -4.
The correct answer is A) y = -4.
4) -13 = m / -5
To isolate m, we can multiply both sides of the equation by -5:
-5 x (-13) = m
65 = m
Therefore, m = 65.
The correct answer is C) m = 65.

Jones of Boston borrowed $40,000, on a 90-day 10% note. After 60 days, Jones made an initial payment of $6,000. On day 80, Jones made an additional payment of $7,000. Assuming the U.S. Rule, what's the adjusted balance of the first payment? (Use 360 days.)
Answer:
$34,666.67
Step-by-step explanation:
Step 1: Calculate the interest for 60 days.
(40000*60/360 )* 0.10 = $666.67
Step 2: Amount = Principal + Interest = $40,000 + 666.67 = $40,666.67
Step 3 : After 60 days, he paid $6000.
Remaining balance of the first payment = 40666.67 - 6000 = $34,666.67

There is a "buy 3 get 1 free" sign for candy bars at the store. Each candy bar cost $0.50. What os the price of 12 candy bars?
$4.50 because 3 were free wich means 9 cost money 9*0.50=4.5
The cost of 12 candy bars with a 'buy 3 get 1 free' offer is $4.50.
Explanation:To calculate the cost of 12 candy bars under the 'buy 3 get 1 free' deal, we need to divide the 12 by the group size, which is 4 (3 that you pay for + 1 that you get for free). This results in 3 groups. Since you only pay for 3 candy bars in each group, each group will cost you $0.50 x 3 = $1.50. So, the total cost for 12 candy bars is $1.50 x 3 = $4.50.

the length of a rectangular swimming pool is triple its width the pool covers an area of 192 m squared
To find the dimensions of the rectangular swimming pool, we can use the formula for the area of a rectangle. The width is 8 meters and the length is 24 meters.
Explanation:To find the dimensions of the rectangular swimming pool, let's assume the width to be 'w' meters. According to the given information, the length of the pool is triple the width, which means the length is 3w meters. To find the area of the pool, we can use the formula: Area = Length × Width.
Given that the area of the pool is 192 m², we can substitute the values into the formula as follows:
192 = (3w) × w
192 = 3w²
Dividing both sides of the equation by 3, we get:
w² = 64
Taking the square root of both sides of the equation, we get:
w = ±8
Since the width cannot be negative, the width of the pool is 8 meters. The length of the pool can be calculated by multiplying the width by 3:
Length = 3 × 8 = 24 meters
Therefore, the dimensions of the rectangular swimming pool are 8 meters by 24 meters.

What is the best way to display a set of data with a wide range, where we want to be able to find the measures of central tendency using the display?
frequency table
line plot
stem-and-leaf plot
histogram
Answer:
stem and leaf plot
Step-by-step explanation:
Final answer:
A histogram is the best choice for displaying a set of data with a wide range to find measures of central tendency, as it effectively groups continuous data into frequency bins.
Explanation:
To display a set of data with a wide range, particularly when looking to find measures of central tendency, a histogram is typically the best choice. A histogram allows you to see the data's distribution by grouping data into 'bins' of equal width. Unlike a bar graph, which is more suitable for discrete categories, a histogram's contiguous rectangles make it ideal for showing the frequency of continuous data. Each bar on the histogram represents the frequency of data within a particular interval, giving an immediate visual summary of the data. This makes it easier to estimate the measures of central tendency such as the mean, median, and mode.
A stem-and-leaf plot could also be useful for smaller data sets, as it displays all data values which assist in identifying the central tendency measures directly. However, for larger and continuous data sets, the histogram is more efficient. A frequency table is another option for displaying the frequency of data grouped into ranges, making it possible to calculate the central tendency measures.

For every 50 emails that Nick sent in a month, he received 30 emails. What is the ratio in simplest form of the number of emails sent to the number of emails received by Nick that month?
The ratio of emails sent to emails received by Nick that month is 5:3 in its simplest form, determined by calculating their greatest common divisor.
Explanation:The subject of your question is ratios and it falls under the category of Mathematics.
'For every 50 emails that Nick sent in a month, he received 30 emails.' This tells us about a ratio. A ratio is a way to compare amounts of something.
The ratio in this case is the number of emails sent by Nick to the number of emails he received. We express this ratio as '50:30'.
To simplify the ratio, we find the greatest common divisor (GCD) of 50 and 30, which is 10. So, we divide both numbers by 10. Thus, our simplified ratio is 5:3.
This means Nick sent 5 emails for every 3 emails he received, in simplest terms.

Step-by-step explanation:
There is an animal farm where chickens and cows live. All together, there are 82 heads and 192 legs. How many chickens and cows are there on the farm?
Answer:
There are 14 cows and 68 Chicken in the farm.
Step-by-step explanation:
A Cow has 4 legs
Chicken has 2 legs.
Lets take there [tex]x[/tex] chickens AND,
there are [tex]y[/tex] number of Cows.
Now we can write two equations for the number of heads and legs.
For the number of heads we can write,
[tex]x+y=82[/tex] <--------- 1st equation
For the number of legs we can write,
[tex]2x+4y=192[/tex] <------ 2nd equation
We can now solve the simultaneous equations to find [tex]x[/tex] and [tex]y[/tex]
Multiply 1st equation by 2 and deduct it from 2nd equation to remove [tex]x[/tex]
⇒[tex]2x+4y-2*(x+y)=192-164[/tex]
⇒[tex]2x+4y-2x-2y)=112-164[/tex]
⇒[tex]2y=28[/tex]
⇒[tex]y=14[/tex]
Therefore, there are 14 cows in the farm.
Now we can substitute the [tex]y[/tex] value to the 1st equation and find [tex]x[/tex] value.
[tex]x+14=82[/tex]
[tex]x=68[/tex]
Therefore, there are 68 chickens in the farm.
