Answers
Answer:
-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

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)

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)/4000x = $11,600Ultimately, the activity variance is favourable bas less commission expense is recorded for less sale.

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.

What is the y-intercept:
7x + y = 10
Answers
Answer:
10
Step-by-step explanation:
7(0)+y=10
y=10
Answer: (0, 10)
Step-by-step explanation:
The given expression is in the standard form of linear equations: Ax + By = C, where A and B are constants.
The definition of y-intercept is the point that intersects with the y-axis, meaning that the [x] value of the point will be zero.
To find the y-intercept of an equation, substitute the [x] variable with 0, as mentioned above, the [x] value of a y-intercept is 0.
[tex]7x+y=10\\[/tex]
[tex]7(0)+y=10[/tex]
[tex]0+y=10[/tex]
[tex]y=10[/tex]
As we find the [y] value is 10, while the given [x] value is 0, therefore, the y-intercept of [tex]7x+y=10[/tex] is [tex]\boxed{(0,10)}[/tex].
