Simplify the expression square root of -25/(5-2i) + (1-3i)
Georgia [21]

Answer:

I guess \frac{25}{6} -5i

Step-by-step explanation:

\frac{-25}{(5-2i)+(1-3i)}              1. rewrite the expression(it helps me tbh)

\frac{-25}{5 - 2i+1-3i}                   2. Distribute the positive symbol to (1-3i)

\frac{25}{6-5i}                           3. treat i as a variable while you combine like terms

\frac{25}{6} -5i                       4. divide 25 by 6-5i but leave 25/6 as a fraction since it can't be divisible.

Solve the following equation 3 by X + 1 is equal to 5 by 2 X linear equation​
dangina [55]

Answer:

  x  = 5

Step-by-step explanation:

A by B is simply \frac{A}{B}

    3 by x + 1 is \frac{3}{x + 1}  

    5 by 2x is \frac{5}{2x}  

So, the equality is ;

                \frac{3}{x + 1} = \frac{5}{2x}  

Cross multiply and solve the inequality;

         3(2x) = 5(x + 1)

         6x  = 5x + 5

          6x -5x = 5

              x  = 5

An antique store increases all of its prices by $40\%$, and then announces a $25\%$-off-everything sale. What percent of the ori
Mandarinka [93]

Answer:

105%

Step-by-step explanation:

We'll analyse the question one step at a time

Let the original price be x.

Let y be the 40% increase

y =x + 40\% *x

Express as decimal

y =x + 0.40 x

y =1.40x

Let z be the 25% off sale

z = (1 - 25\%) * y

Express as decimal

z = (1 - 0.25) * y

z = (0.75) * y

z = 0.75y

Substitute 1.40s for y

z = 0.75*1.40x

z = 1.05x

Express 1.05 as a fraction

z = 105\%  * x

<em>The percentage is 105%</em>
