Answer:

equation

Step-by-step explanation:

To isolate the variable, we must reverse the operations acting on the variable. We do this by performing the inverse of each operation on both sides of the equation. Performing the same operation on both sides of an equation does not change the validity of the equation, or the value of the variable that satisfies it.

Answer:

equation

Step-by-step explanation:

Inverse operations are used to solve simple algebraic equations to more difficult equations that involve exponents, logarithms, and trigonometry. Mathematically, inverse operations are opposite operations. Addition is the opposite of subtraction; division is the opposite of multiplication, and so on.

Express 20% as a fraction in its lowest form? Thanks
lilavasa [31]

✧・゚: *✧・゚:*    *:・゚✧*:・゚✧

                  Hello!

✧・゚: *✧・゚:*    *:・゚✧*:・゚✧

❖ 20% as as a fraction in lowest terms is \frac{1}{5}

Percents are out of 100% so write 20% out of 100% as a fraction:

\frac{20}{100}

Both the numerator and denominator can be divided by 20 so once divided, you get \frac{1}{5}

Taxes= 7,2

Housing = 57,6
