Answer:

Hope this helps! (:

Step-by-step explanation:

By putting the numbers in the given equation,

2x + 3 + 3x = 7x + 9

5x + 3 = 7x + 9

(5x + 3) - 7x = (7x + 9) - 7x

(5x - 7x) + 3 = 9

-2x + 3 = 9

(-2x + 3) - 3 = 9 - 3

-2x = 6

-x = 3

x = -3

Therefore, our equation is correct which has a negative result.

In place of 6 if we use 8, value of x will be negative again.

Anestetic [448]

Answer:

2

Step-by-step explanation:

There would be 3 possible measurements for the 3rd side of the triangle because if you use the hypotenuese formula, you see C^2 = A^2 + B^2 so the two sides could be A and B, or they can be C and A / C and B but the C and __ would be the same for both A and B because they would be added the same way. (they would be equal)

The sample space of picking a 2
Alchen [17]

Answer:

Pr = \frac{1}{15}

Step-by-step explanation:

Given

See attachment for sample space

Required

P(1\ Y\ and\ 1\ P)

From the attached sample space, we have:

n(S) =30 ---- total outcomes

n(PY) = 2 --- outcomes with 1 Y and 1 P = 2 i.e. (P,Y) and (Y,P)

So, the required probability is:

Pr = \frac{n(PY)}{n(S)}

Pr = \frac{2}{30}

Pr = \frac{1}{15}

<em>The error is that; Carlos omitted the numerator</em>

Japanese bullet trains travel at an average speed of 150 miles per hour. If you take the bullet train and leave Tokyo at 9:00 AM
Karo-lina-s [1.5K]

Answer: you would have travelled 500 miles.

Step-by-step explanation:

Distance travelled = speed × time

Japanese bullet trains travel at an average speed of 150 miles per hour.

If you take the bullet train and leave Tokyo at 9:00 AM, by 12:20, it would be noon. The time that you would have spent would be

12:20 - 9:00 = 3 hours 20 minutes.

Converting to hours, it becomes

3 + 20/60 = 3 + 1/3 = 10/3 hours

Therefore, the number of miles that you would have travelled would be

10/3 × 150 = 500 miles
