Answer:

You fill the bags faster. You will finish filling the 7 bags of trash 7 minutes sooner than your friend.

Step-by-step explanation:

Divide 28 minutes by the 2 bags of trash. You fill 1 bag of trash every 14 minutes. 28 ÷ 2 = 14

Your friend fills 1 bag of trash every 16 minutes.

48 ÷ 3 = 16

7 bags × 16 min. = 105 min.

7 bags × 14 min. = 98 min.

105 - 98 = 7 minutes

I need the answer on number 5

I believe Z=18
Example:
2/3z + 1 = 13
Multiply both sides: 2/3z * 3 + 1 * 3 = 13 * 3
Refine: 2/3z + 3 = 39
Subtract from both sides: 2z + 3 - 3 = 39 - 3
Refine: 2z=36
2z/2 = 36/12
Z=18

What is the quotient (x3 – 3x2 + 3x – 2) ÷ (x2 – x + 1)?

timofeeve [1]

We need to find the quotient of the given division problem.

$\frac{x^{3}-3x^{2}+3x-2}{x^{2}-x+1}$

In order to find its quotient, we will use long division.

$x^{2}-x+1$ ) $x^{3}-3x^{2}+3x-2$

First of all, we put x in the quotient as $x^{2}$ goes into $x^{3}$ , x times.

So, we get:

$x^{2}-x+1$ ) $x^{3}-3x^{2}+3x-2$ (x

$\text{ ..................}x^{3}-x^{2}+x$

Upon subtracting, we get:

$\text{....................}-2x^{2}+2x-2$

We can see that $x^{2}$ goes into $-2x^{2}$ , -2 times, therefore, the next term in the quotient will be -2. This makes our quotient as (x-2).

Together Mary, Jane, and Ruth received $30. Mary received $6, Jane received $9, and Ruth received $15. What percent of the $30 d

Likurg_2 [28]

Hey there! :D

So, we know that Jane received $9 out of the $30.

Divide 9 by 30.

9/30= .3

Turn that into a percentage.

.3= 30%

We can check this by finding the other percentages.

Ruth= 15 15/30= .5 50%

Mary= 6 6/30= .2 20%

30%+20%+50%= 100% <== this works

I hope this helps!
