To solve 6x=72 do you use the commutative property?

Addition and multiplication are commutative property so that mean no.

In this case, you have to do division.

Your answer is 6x = 72
x = 12

Hope this helps :)

Answer:

$36.00

Step-by-step explanation:

The formula for simple interest is I = P x r x t where P is the principal amount, $600.00, r is the interest rate, 2% per year, or in decimal form, 2/100=0.02, and t is the time involved, 3....year(s) time periods. So t is 3....year time periods. To find the simple interest, we multiply 600 × 0.02 × 3 to get that the interest is $36.00 . Usually now, the interest is added onto the principal to figure some new amount after 3 year(s), or 600.00 + 36.00 = 636.00.

A body builder consumed 4,400 calories yesterday. Today, he consumed 3,600 calories. What is the percent decrease in number of c

Amanda [17]

4400 - 3600 = 800

Decrease = 800 Calories
Original value was 4400 Calories.

Now,
$\frac{800}{4400} \times 100 \\ = \frac{2}{11} \times 100 \\ = \frac{200}{11} = 18.18 \: \%$

After Rounding off,
Decrease percentage will be 18 %

Answer:

$6\sqrt{2} (\cos(135^{\circ})+i\sin(135^{\circ}))$

Step-by-step explanation:

The angle to the point in the second quadrant is measured from the positive real axis (the x-axis). Second quadrant angles are between 90° and 180°, leaving the 135° choices as the only ones that make sense.

The magnitude of z is the root of the sum of the squares of its components:

|z| = √((-6)^2 +6^2) = 6√2

So, the polar form of z is ...

$\boxed{6\sqrt{2} (\cos(135^{\circ})+i\sin(135^{\circ}))}$

this matches the first choice
