Answers

Step-by-step explanation:

3(b-5) = 27

=> 3b - 15 = 27

=> 3b = 27 + 15 = 42

=> b = 42/3

=> b = 14 (Ans)

2x/3 = 6

=> 2x = 6 × 3 = 18

=> x = 18/2

=> x = 9 (Ans)

2(n + 5) = 15

=> 2n + 10 = 15

=> 2n = 15 - 10 = 5

=> n = 5/2

=> n = 2.5 (Ans)

a + a + a + a = 24

=> 4a = 24

=> a = 24/4

=> a = 6 (Ans)

4c + 6 = 18

=> 4c = 18 - 6 = 12

=> c = 12/4

=> c = 3 (Ans)

-9+30x

Step-by-step explanation:

-3 x 3 is -9

-3 x -10x is 30x

Answer:

-9 + 30x

Step-by-step explanation:

Like you mentioned, to solve this expression we need to use the distributive property...

We have to distribute -3 to 3 and -10x.

When multiplying negative and positive numbers it is important to know that...

-negative times negative equal positive

-negative times positive equal negative

-3 · 3 = -9

-3 · -10x = 30x

Therefore the answer is -9 + 30x

The area of each small square is 16 square centimeters. What is the side length of the​ window? Explain

Answers

Answer:

Length=4 cm

Step-by-step explanation:

Solve for L

L*W=A

16 cm^2=L*W

Since this a square. W will equal L.

So [tex]\sqrt{16} =4[/tex]

Meaning that the length is 4    

The area of a square is given by:

Area = Side²

If the area of a square is 16 square centimeters, the side length of the window is 4 cm.

What is a square?

A square is a four-sided polygon, whose all sides are equal in length and whose opposite sides are parallel to each other.

We have,

Area of the square = 16 square centimeters

The area of a square is given as:

Area = side²

Area = 16 cm²

16 cm² = side²

Square root on both sides
[ 4² = 16 ]

√16 cm² = √side²

Side = 4 cm

Thus if the area of the square is 16 square centimeters, the side length of the window is 4 cm.

commission expense is budgeted to be $16,000 at a planned sales level of 4,000 units. if only 2,900 units are sold, how much commission expense will appear on the flexible budget, and is the activity variance favorable or unfavorable?

Answers

The amount of commission expense that will appear on the flexible budget if 2900 units were sold is; $11600

The activity variance is favourable.

According to the question;

The budgeted commission expenses is to be $16,000 at a planned sales level of 4,000 units.However, only 2900 units are sold.

To solve this;

We must be aware that the commission expense is directly proportional to the number of units sold.

In essence;

$16,000 is expected at 4,000 units of sale.Therefore, $x is expected at 2,900 units of sale.

By cross product;

x = (2900 × 16000)/4000

x = $11,600

Ultimately, the activity variance is favourable bas less commission expense is recorded for less sale.
