add 0+1+2+3+4 = 10

divide 10÷5 = 2

divide 30÷5 = 6

the ratio is 2:6 which simplifies to 1:3 by the means of lates per student. In other words there is one late per 3 students.

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>
