Which of the following equations have the solution v=3v=3?
kari74 [83]

ANSWER:

v = 3 is only a solution to equations 1 and 5.

STEP-BY-STEP EXPLAINATION:

Equation 1:

\frac{v}{3}   + 9 = 10

\frac{v}{3} = 10 - 9

\frac{v}{3} = 1

v = 1(3)

v = 3

Therefore, v = 3 is a solution.

Equation 2:

4 = 7v - 24

4 + 24 = 7v

28 = 7v

\frac{28}{7}  = v

4 = v

Therefore, v = 3 is not a solution.

Equation 3:

16 = 2 + 5v

16 - 2 = 5v

14 = 5v

\frac{14}{5}  = v

Therefore, v = 3 is not a solution.

Equation 4:

5 - 7v = 19

- 7v = 19 - 5

- 7v = 14

v =  \frac{14}{ - 7}

v = -  2

Therefore, v = 3 is not a solution.

Equation 5:

3 + 2v = 9

2v = 9 - 3

2v = 6

v =  \frac{6}{2}

v = 3

Therefore, v = 3 is a solution.

Write 5600 in standard form
Mrac [35]

Answer:

5.6 x 10^3 (10 to the power of 3)

i.e. 5600 = 5.6 x 10^3 because you have to go back 3 times to get 5.6 *you cannot have a number less than 1 or more than 10*

So the power of 3 is the amount of times you had to move back

Step-by-step explanation:

This is how you write 5600 in standard form!

What is the value of B??
Maurinko [17]
The answer is 3.75.

Since the length of 'b' is one-half that of 7.5 based on the diagram (we know this because the partial radii connecting the two lines, or chords, are the same length, meaning the two chords are equal);

   <u>7.5</u>      ⇒   3.75<u>
