Answer:

Value of the unknown quantity for which from given equation we get true numerical equality is called root of that equation. Two equations are called equivalent when the multitudes of their roots match, the roots of the first equation are also roots of the second and vice versa. The following rules are valid:

1. If in given equation one expression is substituted with another identity one, we get equation equivalent to the given.

2. If in given equation some expression is transferred from one side to the other with contrary sign, we get equation equivalent to the given.

3. If we multiply or divide both sides of given equation with the same number, different from zero, we get equation equivalent to the given.

Equation of the kind ax+b=0, where a,b are given numbers is called simple equation in reference to the unknown quantity x.

Answer: the system of equations are

0.1x + 0.04y = 162

y = 2x

Step-by-step explanation:

Let x represent the total dollar amount of the phone sales she makes.

Let y represent the total dollar amount of the computer sales she makes.

Charlotte earns a 10% commission on the total dollar amount of all phone sales she makes, and earns a 4% commission on all computer sales. If she earned a total of $162 in commission, it means that

0.1x + 0.04y = 162

Charlotte had twice as much in computer sales as she had in phone sales. This means that

y = 2x

We have to divide using long division.
__4
4| 19
16
3

The divisor becomes the denominator, the remainder becomes the numerator, and the quotient becomes the whole number.

So we have:

$\sf4\dfrac{3}{4}$

Which of the following

Black_prince [1.1K]

Answer:

Step-by-step explanation:

-12 = 3/4n + 8....subtract 8 from both sides

-12 - 8 = 3/4n

-20 = 3/4n.....multiply both sides by 4/3, cancelling the 3/4 on the right

-20 (4/3) = n

-80/3 = n
