Answer:

x = \frac{5}{2}

Step-by-step explanation:

Given

\frac{5}{8} x + 2 = \frac{57}{16}

Multiply through by 16 to clear the fractions

10x + 32 = 57 ( subtract 32 from both sides )

10x = 25 ( divide both sides by 10 )

x = \frac{25}{10} = \frac{5}{2}

jeyben [28]

Answer:

The set of needed equations is

h = 30 m

11 m +  3  h = 909  where

the driver drove for m hours.

h : distance covered in m hours

Step-by-step explanation:

Here, according to the question:

The per hour rate of driver  = $11

The gas maintenance expense = $3 per mile.

The total distance covered by drives is 30 miles per hour.

The total  expenses paid to driver  = $909

Now, let us assume the driver drove for m hours.

The average speed of driver was 30 miles / hour

⇒ Driver covers 30 miles in 1 hour

SO, distance covered in m hours  = h = m x 30 = 30 m

or, h = 30 m

So,according to the question, the total amount paid :

Charges of m hours driving + maintenance charges for h miles

= 11 m + 3( h)

or, 11 m +  3  h = $909

Hence the set of needed equations is

h = 30 m

11 m +  3  h = 909

Express the radical using the imaginary unit, i
Kipish [7]

Answer:

7i.

Step-by-step explanation:

Note : The given expression must be \sqrt{-49}.

We have to write this radical value in the imaginary value.

The given value can be rewritten as

\sqrt{-49}=\sqrt{49\times (-1)}

\sqrt{-49}=\sqrt{49}\times \sqrt{-1}    [\because \sqrt{ab}=\sqrt{a}\sqrt{b}]

\sqrt{-49}=7\times i    [\because \sqrt{-1}=i]

\sqrt{-49}=7i

Therefore, the required expression is 7i.
