Answers

Answer:

-103

Step-by-step explanation:

Answer:  -103

Step-by-step explanation:

y=7 so 7x(-7)= -49 because a negative times a positive always equals a negative. Same thing for 9x. x=(-6) so 9x(-6)=-54.  So (-49)+(-54)= -103

3. What is the solution set of the equation 3x + 5) = x + 2?

Answers

the solution set of 3x+5=x+2 is x=-1. This is because you want to get the variables on one side and the numbers on the other. you subtract x on both sides and subtract 5 on both sides. your equation then becomes 3x=-3. you then divide 3 on both sides and you get your answer of x=-1.

$67.34. if you multiply the total amount of money he has (259) by the percentage of (74) you will get (19,166). you then will divide the total by (100). which then gives you ($191.66) that will be given off. so you then subtract the total of money he has (259) by (191.66) which will give you (67.34). he will be paying ($67.34).

  322

Step-by-step explanation:

Consider the cube ...

  (a +b)³ = a³ +3a²b +3ab² +b³

  = a³ +b³ +3ab(a+b)

Now, for a=x and b=1/x, we have ...

  (x +1/x)³ = x³ +1/x³ +3(x)(1/x)(x +1/x)

Using the known value for x+1/x, this is ...

  7³ = x³ +1/x³ +3(7)

  x³ +1/x³ = 7³ -3·7 = 343 -21

  x³ +1/x³ = 322

find the length of the missing side

Answers

Answer: x=12

Step-by-step explanation:

20 squared= 400 and 16 squared= 256. The Protagorean Theorm is a sqaured plus b sqaured equals c squared. You just reverse the Theorm to C sqaured minus B squared= A squared. 400-256=144 (12x12= 144)

Answer:
x=12

Explanation:
To solve this question, we need to use the equation a^2+b^2=c^2.

A and B are the sides of the right triangle that are perpendicular to each other and C is the diagonal side. So, in this case, a=16, b=x and c=20.

1) plug values into the equation
a^2+b^2=c^2
16^2+x^2=20^2
2) expand the squares
256+x^2=400
3) Subtract both sides by 256
x^2=400-256
x^2=144
4)Square root both sides
x=12

Mina asked four friends to explain how each one solved the expression . Here are their explanations Please comment if these are the same:

Ivy’s explanation: I lined up the numbers to subtract.

 176.3

- 15.75

 18.8

Hannah’s explanation: I lined up the two decimals according to place value. I put a 0 in the hundredths place to make it easier for me to subtract.

 161.45

Jose’s explanation: I lined up the two decimals according to place value.

176.3

- 15.75

 161.45

An’s explanation: I counted up from 15.75 to 176.3 to find the difference. I underlined each number I added on each line.

15.75 + 0.25 = 16

16 + 4 = 20

20 + 150 = 170

170 + 6 = 176

176 + 0.3 = 176.3

I rearranged the underlined numbers to make them easier to add: .

150 + 6 + 3 + 0.25 = 163.25

Explain each student’s mistake and solve the problem correctly.

X is greater than negative eight and less than eight and the dots are marking the numbers on the number line

Is that the right answer ?

Answers

Answer:

Yes, that is correct

Step-by-step explanation:

The formula for the slope can be referred to as "rise over run", a fraction where the rise (change in the y direction) is divided by the run (change in the x direction).

We can get the rise and run by choosing two points on the slope and looking for the change in the x and y direction. In this case, let us use the points (-4,0) and (0,-5). The change in the y direction is from 0 to -5, thus the rise will be -5. Likewise, the change change in the x direction is from -4 to 0 and the run will be 4.

Going back to "rise over run", we divide the rise by the run, giving us -5/4

At what angular speed should the ring rotate so the occupants feel that they have the same weight as they do on Earth Stephen says that the numbers 38 and 40 are relatively prime. Explain why he is incorrect in making this statement. (make a good explanation plz) Firms face competing pressures in the marketplace-how to achieve lower costs through proven approaches to production, while looking at how to maximize their effectiveness in local markets. A firm's choice of strategy must reflect these pressures, and the firm knows that the dynamics of competition may require changes in strategy. Pressures for local responsiveness mean that a firm may not be able to realize the full benefits from economies of scale, learning effects, and location economies. Customization of products brings benefits, but it also limits the firm's ability to realize significant scale economies and location economies. Companies generally choose from four main strategic postures: a global standardization strategy, a localization strategy, a transnational strategy, or an international strategy. The appropriateness of each strategy varies given the competitive realities and the firm's core competences.Read the case below and answer the questions that follow. Your firm has been a leader in several lines of fast-moving consumer goods. The firm has been following a localization strategy. Your products have been distributed in a number of foreign markets and regions, and they are distinct enough in local markets to respond to national tastes and preferences. Competition, however, has become more intense, with many competitors using lower cost structures to undercut your prices and still satisfy your customers. The firm must decide what kind of strategy it needs to follow to meet the demands of the local markets as well as the increased competitive pressures on cost. a. leverage skills and products associated with a firm's core competencies from one country to another. b. monitor and adapt to changing customer tastes in a large number of foreign markets. c. compete effectively in more than one international market.
