Answer:
n=10
Step-by-step explanation:
[tex] - 4(2 + 8) = ( - 4 \times n) \\ \frac{ - 4(10)}{ - 4} = \frac{ - 4n}{ - 4} \\ 10 = n[/tex]
Answer:
−4(2+8)=−4n
Step 1: Simplify both sides of the equation.
−40=−4n
Step 2: Flip the equation.
−4n=−40
Step 3: Divide both sides by -4.
[tex]\frac{-4n}{4} = \frac{-40}{-4}[/tex]
n=10

Answer:
Step 2: 47
Step 3: 84
Step 4: 114
Step-by-step explanation:
Step 2: The width is 21, and the length is 36.
Sum is addition, so it would be 21 + 36.
21 + 36 = 47
Step 3: 47 x 2 = 84
Step 4: Perimeter is all around, whilst area is on the inside. The length is 21, so it is 21 + 21. 21 + 21 is 42. The width is 36, so it is 36 + 36, which is 72. 72 + 42 = 114.

Question:
A running club keeps track of the number of hours each person has trained for a race and the length of time it takes the person to run the race. A scatter plot is graphed with the x-axis indicating the number of hours a runner has trained and the y-axis indicating the time, in minutes, it took to run the race. The equation y = 60 - 0.5x is used as the line of best fit of the data. What does the slope of the equation represent?
options:
a
Runners will decrease their race time by 2 minutes for every 1 hour they have trained.
b
Runners will increase their race time by 2 minutes for every 1 hour they have trained.
c
Runners will increase their race time by 1 minute for every 2 hours they have trained.
d
Runners will decrease their race time by 1 minute for every 2 hours they have traine
The solution is, 60 minutes is a good prediction of how long it will take Tom to run the 6 mile race.
What is scatter plot?A scatter plot is a type of plot or mathematical diagram using Cartesian coordinates to display values for typically two variables for a set of data. If the points are coded, one additional variable can be displayed.
Here, we have,
We are given the scatter plot which shows the distance he has run and the time it took for each run.
We are asked to determine a good prediction of how long it will take Tom to run the 6 mile race?
One way to predict the time is by drawing a line that best fits the given data.
As you can see, from the line of best fit, the time corresponding to the 6 miles is around 60 minutes.
Therefore, 60 minutes is a good prediction of how long it will take Tom to run the 6 mile race.

Using inverse operations is a direct way to solving equations
What is the Golden Rule for solving equations?
Answer:
Do unto one side of the equation, what you do to the other!
Step-by-step explanation:
An equation is like a balance scale. If we put something on, or take something off of one side, the scale (or equation) is unbalanced. When solving math equations, we must always keep the 'scale' (or equation) balanced so that both sides are ALWAYS equal.
Answer:
Keeping the equation balanced.
Step-by-step explanation:
You need to keep the equation balanced on both sides of the equal sign, like when you need to get rid of the number 4 on one side you have to do the same thing on the other side.
I need to get aleks done on june 3oth
Answer:
3.2
Step-by-step explanation:
Since it is similar, we know that the sides are gonna be directly proportional so
QR (6.4) / BC (4) = scale factor of 1.6
1.6 x 2 = 3.2

Answer:
9. y = 8
10. n = 21
11. 44 = v
12. c = 35
Step-by-step explanation:
9. 9y = 72
Divide each side by 9
9y/9 = 72/9
y = 8
10. 3n = 63
Divide each side by 3
3n/3 = 63/3
n = 21
11. 4 = v/11
Multiply each side by 11
4*11 = v/11*11
44 = v
12. c/7 = 5
Multiply each side by 7
c/7*7 = 5*7
c = 35
What is the area of the figure below?
Answer:
68 in
Step-by-step explanation:
Because the area of the squares is 3 x 3 = 9 and because there are two squares it is 18. The area of the central figure is 50 because i divided it into 4 triangles and 2 rectangles, each rectangle is 15 in and each triangle is 5 in so 15 x 2 = 30, 5 x 4 = 20 and 30 + 20 + 18 = 68
How many millimeters are equal to one kilometer?
Metric
1 kilometer = 1,000 meters
1 meter = 100 centimeters
1 meter = 1000 millimeters
1 centimeter = 10 millimeters
Answer: The answer would be 1,000,000, or one million.
Step-by-step explanation:
There are 1000 millimeters in a meter, and there is the same number of meters in one kilometer. So to solve for how many millimeters are in one kilometer, just multiply 1000 by 1000 to get 1,000,000. Hope this helps!

The display at an aquarium has sea stars and eels in a ratio of 4:5. It also has 5/8 as many rockfish as sea stars. There are 40 more wolf eels than rockfish. How many Sea stars are there?
64 sea stars in the aquarium.
What is Ratio?Ratio is defined as a relationship between two quantities, it is expressed one divided by the other.
Ratio of see stars to eels = S : E = 4:5
E = 5/4(S)
Ratio of rockfish to sea strars = R : S = 5:8
R = 5/8(S)
E = R + 40
5/4(S) = 5/8(S) + 40
Multiply by 8 both the sides
10S = 5S + 320
5S = 320
S = 320/5
S = 64
Hence, 64 sea stars in the aquarium

Describe, in great detail, how you would graph a line that is in slope-intercept form.
Use y=-3x+ 5 as your example.
Hi there!
»»————- ★ ————-««
Please see the explanation below.
»»————- ★ ————-««
Explanation:
Recall the meanings of the variables in the slope-intercept equation.
⸻⸻⸻⸻
[tex]\boxed{\text{\underline{Slope Intercept Form:}}}\\\\y=mx+b\\---------------\\\boxed{\text{Key:}}\\\\\rightarrow \text{m - slope}\\\rightarrow \text{b - y - intercept}[/tex]
⸻⸻⸻⸻
We already have one point given, the y-intercept. The y-intercept of a line when given a slope intercept form equation is: [tex](0, b)[/tex]Using the example, we would graph the point (0,5) as our first point.⸻⸻⸻⸻
To graph the second point, we need to understand the meaning of slope. The slope of a line can be remembered as 'rise over run'.The slope for the given equation is -3. This means we would have to go three units down and then one unit right from the y-intercept. Our new point would be (1,2).⸻⸻⸻⸻
The result should be the graph attached.»»————- ★ ————-««

Ahmad’s goal is to exercise for a mean of 45 minutes per day for one week. For the first six days of the week, he exercised 35, 40, 37, 42, 45, and 50 minutes. What is the number of minutes Ahmad must exercise on the 7th day to meet his goal for the week?
Answer:
41.5
Step-by-step explanation:
To find the mean, your supposed to add all the numbers you have and divide by how many numbers there are. In this question your numbers are 35, 40,37,42,45, and 50.
If you add them all up you get 249. Your next step is to divide by how many numbers there are. Since there are 6, your equation will now be 249 divided by 6. Your answer is now 41.5
So on the 7th day Ahmad exercised for 41.5 minutes. If you need to round then maybe 41 minutes.
Answer:
41.5
Step-by-step explanation:
On the 7th day Ahmad exercised for 41.5 minutes and if you want to put it simply its 41 minutes.

Answer:
448
Step-by-step explanation:
I = Prt where I is the interest P is the principle r is the rate and t is the time
I = 400 * (.02) * 6
I = 48
The amount in the account is the interest plus the original amount
400 +48
448
Answer:
$ 448
Step-by-step explanation:
amount that Elena deposit (P) =$ 400
rate of interest (R)=2%
time (T)=6 years
formula to find interest is
Interest = PTR/100
=$400*6*2/100
=$4800/100
=$48
Total amout she receives after 6 years is
Amount = Interest + Principal
=$48 + $400
=$448
