Answer:

p=-36

Step-by-step explanation:

-18=p/2

______________________

Multiply both sides by 2

-18(2)= p/2 (2)

______________________

-36 = p

switch the sides of the equation

______________________

p=-36

First, of all
in the equation
$- 18 = p \div 2$
you want to make 'p' alone so,
move 2 by the opposite of division,
Multiplcation
$- 18 \times 2 = - 36$
so
$p = - 36$
I hope I was able to help you

i don’t know how to divide integers and i have a test tomorrow based on adding subtracting multiplication and division on intege

ryzh [129]

In order to divide integers, the first thing to check is the sign:

- When dividing two positive integers, the result will be a positive integer.

- When dividing two negative integers, the result will be a positive integer.

- When dividing integers with different signs (one negative and one positive), the result will be a negative integer.

Then, after checking the sign, we need to calculate the value of the division.

Some examples of divisions are:

$\frac{24}{8},\frac{-15}{5},\frac{-100}{-10}$

In the first division, the result is 3, because we have that 8 * 3 is equal 24.

Also, both numbers are positive, so the result is also a positive number.

In the second division, the result is -3, because 5 * (-3) is equal -15.

The result is negative, because the two numbers have different signs.

In the third division, the result is 10, because -10 * 10 is equal -100.

The result is positive, because both numbers are negative.

Let x be a positive integer. If (-3)ºx (-3)* = (-3)14,<br> what is x?

Nezavi [6.7K]

Answer:

$-3^{\circ \:}x\left(-3\right)=\left(-3\right)\cdot \:14 : x = \frac{840}{180^{\circ \:}}$

Decimal Form:

$x = -267.38030...$

Step-by-step explanation:

$-3^{\circ \:}x\left(-3\right)=\left(-3\right)\cdot \:14$

Remove Parentheses: $(-a) = -a$

$-3^{\circ \:}x\left(-3\right)=-3\cdot \:14$

Multiply the numbers: $3 * 14 = 42$

$-3^{\circ \:}x\left(-3\right)=-42$

Divide both sides by: $-3^{\circ \:}\left(-3\right)$

$\frac{-3^{\circ \:}x\left(-3\right)}{-3^{\circ \:}\left(-3\right)}=\frac{-42}{-3^{\circ \:}\left(-3\right)}$

Simplify:

$x=-\frac{840}{180^{\circ \:}}$

Hope I helped. If so, may I get brainliest and a thanks?

Thank you, have a good day! =)

If 6 people want to share a 30 pound bag of beans equally by weight how many pounds of beans should each person get? Between wha

sertanlavr [38]

Answer:

The 6 people would each get 5lb. of beans. 5 lies between 4 and 6.

Step-by-step explanation:

To get the answer to this problem, all you have to do is divide the total pounds of beans by how many people there are. 30 ÷ 6= 5, so each person would get 5 pounds. Since 5 comes between 4 & 6, you can use that as your answer.
