1. Select All The Equations That Have No Solution.a. +6=5+b. -2(3)=-2+6c. 44=3+2d. 4(+1)=3(+2)e. 53=-3+4

Answers

Answer 1

Answer:

a, and e.

Step-by-step explanation:

x+6=5+x has no solution. When you subtract 6 from both sides, you get x=-1+x. We know that x doesn't equal -1+x, so this equation has no solution.

-2(x-3)=-2x+6 has a solution. When you distribute, you get -2x+6=-2x+6.

4-4x=3x+2 has a solution. Subtract 4 from both sides to get -4x=3x-2. Subtract 3x from both sides to get -7x=-2, then divide -2 by -7 to get x=0.285714285714. This equation has a solution.

4(x+1)=3(x+2) has a solution. Distribute to get 4x+4=3x+6. Subtract 4 from both sides to get 4x=3x+2. Subtract 3x from both sides to get x=2. This equation has a solution.

5-3x=-3x+4 has no solution. Subtract 5 from both sides to get -3x=-3x-1. We know that -3x does not equal -3x-1, so we can determine that this equation has no solution.

Answer 2

Answer:

a  and e has no solution

Step-by-step explanation:

A) x + 6 = x +5

Subtract x from both sides

   x + 6 - x = x + 5 - x

        6 = 5 which is not true.

So, this equation has no solution

d) 5 - 3x = -3x + 4

Add 3x to both sides

5- 3x + 3x = -3x + 4 + 3x

5 = 4         which is not true.

So, no solution

The probability of the spinner landing on A is 3/8, the probability of the spinner not landing on C or E is 1/2

What is probability?

It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

1) What is the probability of the spinner landing on A:

Total outcomes = 8

Total favourable = 3 (A repeated 3 times)

Probability = 3/8

2) Do you have an equal chance of landing on either B or E:

No, because the probability for B is 1/8 and the probability for E is 3/8

3) What is the probability of the spinner not landing on C or E:

P(not landing on C or E) = 4/8 = 1/2

4) Do you have an equal chance of landing on either B or C:

Yes, because both event has same probability = 1/8

5) What is the probability of the spinner not landing on A or E:

P(not landing on A or E) = 2/8 = 1/4

6) What is the probability of the spinner landing on C or E:

P(landing on C or E) = 4/8 = 1/2

7) What is the probability of the spinner not landing on A or B:

P(not landing on A or B) = 4/8 = 1/2

Similarly, we can find the rest of the probability.

Thus, the probability of the spinner landing on A is 3/8, the probability of the spinner not landing on C or E is 1/2

The table shows the number of bottles of different kinds of juice sold at a cafeteria on Monday.

If the cafeteria has 80 customers on Tuesday, which prediction for Tuesday is NOT supported by the data in the table?
Pls answer ASAP

Answers

Answer:C

First you need to add up everything to find out the amount of costumers more Monday. You will get 40. Then you would have to multiply 40 by 2 to get 80 which is the total amount of costumers for Tuesday. This means that you have to double the amount of everything on the table to find out how much of each item was sold. The questions says which is NOT supported by the table. When you do the math you see that everything is accurate except C because the number of apple juice sold on Tuesday is 22 and the number of cranberry juice sold on Tuesday is 14. 22 is not 6 times more than 14 which makes C the correct answer.

help I cant remember what is A slope

Answers

Answer: A slope is basically basically a number that describes the steepness and direction of the line.

To solve for a slope of the line, it is simply rise/run

RISE = How much did the line go up

RUN = How much did the line go in a horizontal fashion

slope is the how much the graph grows by. to find slope you can find the rise/run which is like looking at a graph a drawing a triangle on the box and you put how many boxes they rise by and you put that over run. if you need more help just search up rise over run and it’ll give you more on what im talking about

PLZ, QUICKLY IT IS HOMEWORK Two trains leave the same station at the same time, but are headed in opposite directions. One train travels at 70 mph and the other train travels at 80 mph. How long after they leave the station will they be 50 km apart?

Answers

Answer:

20 minutes( 0.3333 hours) after they leave the station will they be 50 km apart, if the Two trains on opposite tracks leave the same station at the same time. One train travels at an average speed of 80 km/hr and the other travels at an average speed of 70 km/hr.

Step-by-step explanation:

The given is,

                  One train travels at an average speed of 80 km/hr

                  The other travels at an average speed of 70 km/hr

Step:1

     Formula to calculate the distance traveled by two trains,

     Distance traveled by two trains = (Rate of speed of train one +

                                                          Rate of speed of other train) × Time

        From the given the above equation becomes,

        Let, h = Time taken to each the distance

                                         50 = ( 80 + 70 ) h

                                           50 = (150) h

                                             

                                                 = 0.3333 hours

                                                 = ( 0.333 × 60 )          ( ∵ 1 hr = 60 minutes )

                                               h = 20 minutes

Step:2

           Check for solution,

           From equation (1),

                          50 = ( 80+70 ) (0.3333)

                          50 = (150)(0.3333)

                          50 = 50

Result:

         20 minutes( 0.3333 hours) after they leave the station will they be 50 km apart.

Generally, an organization should use the same type of forecasting models for all of their products, regardless if they are new product innovation ideas or already existing products.TRUE or FALSE: transparency? It's the leadership of the business. Transparency must start at the top. In order for a business to be transparent, its people need to be transparent. A culture of transparency takes shape when leaders intentionally manifest their own personal transparency, and encourage it in the attitudes and behaviors of their team members. In other words, transparency starts with 7 people. When an organization's people are transparent, then the organization is ready to follow. Transparency is one of those subtle things that can make a dramatic impact on a business. Yes, it will impact your bottom line. But that's not the whole point. The point is that it helps everyone do business better - you, your clients, your team member.
