Solve the equation. 12=2+z/-6

Bogdan [553]

Answer:

$\boxed{\bold{z=-60}}$

Step-by-step explanation:

Switch Sides

$\bold{2+\frac{z}{-6}=12}$

Subtract 2 From Both Sides

$\bold{2+\frac{z}{-6}-2=12-2}$

Simplify

$\bold{\frac{z}{-6}=10}$

Multiply Both Sides By -6

$\bold{\frac{z\left(-6\right)}{-6}=10\left(-6\right)}$

Simplify

$\bold{z=-60}$

PLEASE HELP!!!

Ksju [112]

ANSWER

$a = 1,2,3,6$

EXPLANATION

The given equation is

$ax = 6$

Divide both sides by $a$

$\Rightarrow \: \frac{ax}{a} = \frac{6}{a}$

Cancel out common factors on the left hand side,

$\Rightarrow \: x = \frac{6}{a}$

For this solution to be a whole number, then $a$ should be a factor of
$6$ .

The reason is that, factors of 6 will divide exactly in to 6 without a remainder, making the answer a whole number.

The whole numbers that are factors of 6 are,

$1,2,3 \: and \: 6$

Note that, the set of whole numbers are,

{ $0,1,2,3,4,...$ }

How can I do this question

TiliK225 [7]

Hello!

First you have to find the area of the floor

To do this you multiply the sides

4 * 4 = 16

Next you find the area of the rug which is a circle

The equation for this is A = $\pi r^{2}$

r is radius

Put in the values you know

$A = \pi 1.5^{2}$

A = 7.07

Subtract this by the area of the floor

16 - 7.07 = 8.93

The answer is 8.93m squared

Hope this helps!
