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

y=8
n=21
v=44
c=35

Using inverse operations is a direct way to solving equations

What is the Golden Rule for solving equations?

Answers

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.

Answers

Answer:

6. x = 16

7. n = -11

Step-by-step explanation:

6. -7(x-6)=-70

= -7x + 42 = - 70

= - 7x = - 70 - 42

= -7x = -112

= -7x/-7 = -112-/7

= x = 16.

7. 9 + n= - 2

= n= -2 - 9

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

Answers

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!

It will equal 1,000,000 kilometres

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

Answers

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.

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
