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

= n = -11

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.

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.

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

What is the area of the figure below?

Answers

answer: 88in^2
explanation: by separating the figure into easier pieces, simple triangles and rectangles, this problem becomes much easier.
by looking the overall length of the figure, we get 7, if you cut off the big rectangle in the middle from that seven, you end up with a diamond with a height of 10 and a length of 4. multiply those together to get the area of the points on either side.
10 x 4 = 40
now looking back at the rectangle, by adding up the heights, you get a height of 16. multiply this with the length of 3 and you get 48.
add the two and you get the total area.
40 + 48 = 88

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

2/3 a - 1/6 = 1/3

answer this math question asap pls

Answers

Answer:

a=3/4

Step-by-step explanation:

1. Get 2/3a by itself.

•Turn 1/3 to 2/6 by multiplying 1/3 by 2/2.

•Because you only add and subtract like denominators

This will make it look like:

2/3a - 1/6 = 2/6

Then, add 1/6 to both sides to get 2/3a by itself.

It'll look like this:

2/3a = 3/6

2. Get a by itself.

•Multiply the reciprocal (opposite) of 2/3 to get a alone.

This will look like:

(3/2) • 2/3a = (3/2) • 3/6

a = 18/24

3. Simplify.

Find the largest number that can simplify the equation.

For example, 18 ÷ 3 = 6, and 24 ÷ 3 = 8.

But the largest number you can divide both sides by is 6.

18 ÷ 6 = 3 and 24 ÷ 6 = 4.

3/4.

the answer is a= 3/4

Passage 1excerpt from William Jefferson Clinton, Second Inaugural Address, January 20, 1997 This is the heart of our task. With a new vision of government, a new sense of responsibility, a new spirit of community, we will sustain America's journey. The promise we sought in a new land we will find again in a land of new promise. In this new land, education will be every citizen's most prized possession. Our schools will have the highest standards in the world, igniting the spark of possibility in the eyes of every girl and every boy. And the doors of higher education will be open to all. The knowledge and power of the Information Age will be within reach not just of the few, but of every classroom, every library, every child. Parents and children will have time not only to work, but to read and play together. And the plans they make at their kitchen table will be those of a better home, a better job, the certain chance to go to college.Passage 2adapted from Herbert Hoover, Inaugural Address, Monday, March 4, 1929 Although education is primarily a responsibility of the States and local communities, and rightly so, yet the Nation as a whole is vitally concerned in its development everywhere to the highest standards and to complete universality. Self-government can succeed only through an instructed electorate. Our objective is not simply to overcome illiteracy1. The Nation has marched far beyond that. The more complex the problems of the Nation become, the greater is the need for more and more advanced instruction. Moreover, as our numbers increase and as our life expands with science and invention, we must discover more and more leaders for every walk of life. We cannot hope to succeed in directing this increasingly complex civilization unless we can draw all the talent of leadership from the whole people. One civilization after another has been wrecked upon the attempt to secure sufficient leadership from a single group or class. If we would constantly refresh our leadership with the ideals of our people, we must draw constantly from the general mass. The full opportunity for every boy and girl to rise through the selective processes of education can alone secure to us this leadership.Which of the following topics is only discussed in Passage 2? A. the need to overcome illiteracy B. the need for good leadership C. the importance of family time D. the importance of a good job Why does the narrator lie to her piano teacher about where hermother is?In the white umbrella Seala los adjetivos en estos grupos de palabras.la fruta est buensimalos fascinantes astronautasun laberinto imposible Which of the following does NOT give you congruent angles?CPCTCMidpointAlternate Interior AnglesTriangle Sum Theorem Given csc(A) = 65/16 and that angle A is in Quadrant I, find the exact value of sec A in simplest radical form using a rational denominator .
