Can someone please help me (6th grade math) please and thank you!
Assoli18 [71]

Answer and Step-by-step explanation:

First, you create an expression that equals the perimeter of the shape.

5r + 2s + 3r + 2s + 5r + 2s + 3r + 2s

<u>Simplify</u>

16r + 8s

Now we look at the students' expressions.

I can see that Brain's expression is equivalent to perimeter of the shape. Do you know why?

It is because his answer is the un-distributive version of our answer.

He simply took out the common number that is in 16 and 8, which 8.

<u>So, Brian is correct.</u>

Given parallelogram ABCD, diagonals AC and BD intersect at point E. AE=2x, BE=y+10, CE=x+2 and DE=4y−8. Find y.
hodyreva [135]

9514 1404 393

Answer:

  B. 6

Step-by-step explanation:

The diagonals of a parallelogram intersect at their midpoints, so ...

  DE = BE

  4y -8 = y +10

  3y = 18 . . . . . . . add 8-y

  y = 6 . . . . . . . . divide by 3

__

<em>Additional comment</em>

The value of x is found the same way:

  2x = x+2   ⇒   x = 2

Use IF functions to calculate the regular pay and overtime pay based on a regular 40-hour workweek in cells E5 and F5. Pay overt
g100num [7]

Excel formulas are expressions used to perform computation.

  • The Excel formula to enter in cell E5 is =IF(D5<$B$21,D5,$B$21) * C5
  • The Excel formula to enter in cell E5 is =IF(D5>$B$21,(D5-$B$21) * C5 * $B$22, 0)
<h3 /><h3>The regular pay</h3>

From the complete question, cell B21 represents base work hour

So, we start by checking if the work hour in cell D5 is less than the base work hour in cell B21

If yes, the work hour remains D5; otherwise the work hour is cell B21

The work hour is then multiplied by the rate in cell C5

Hence, the Excel formula to enter in cell E5 is =IF(D5<$B$21,D5,$B$21) *

<h3>The overtime pay</h3>

Here, we start by checking if the work hour in cell D5 is greater than the base work hour in cell B21

If yes, the overtime hour the difference between D5 and B21; otherwise the overtime hour and pay is 0

The over time hour if there is, is then multiplied by the rates in cells C5 and B22

Hence, the Excel formula to enter in cell E5 is =IF(D5>$B$21,(D5-$B$21) * C5 * $B$22, 0)
