Answer:
In the expression [tex]\dfrac{60 \cdot x}{x + 3} -10[/tex] what the constant term -10 represents is;
A. The constant -10 represents the cost of setting up the food stall even if no cheeseburgers were sold
Step-by-step explanation:
Whereby the expression is as given in a similar question which is presented as follows;
[tex]\dfrac{60 \cdot x}{x + 3} -10[/tex]
Where the expression represents the total money earned when a food stall is set up at a fair where 'x' stands for the number of cheeseburgers sold
Then when no cheeseburger were sold, x = 0, such at the start just after setting up the food stall, we then have;
[tex]\dfrac{60 \times 0}{0 + 3} -10 = -10[/tex]
Therefore, the money earned at the start = -10
∴ The money spent at the start = 10
Therefore, the constant -10 represents the cost of setting up the food stall even if no cheeseburgers were sold.

What is the slope of the line 4x – 2y = 5?
–4
–2
2
4
Answer:
It is 2.
Step-by-step explanation:
The equation becomes -2y=-4x=5
But you divide by -2 to get y solo. So -4/-2=2.
Answer:
slope = 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
4x - 2y = 5 ( subtract 4x from both sides )
- 2y = - 4x + 5 ( divide all terms by - 2 )
y = 2x + [tex]\frac{5}{2}[/tex] ← in slope- intercept form
with slope m = 2

Step-by-step explanation:
Put the numbers in order from least to greatest.
72, 73, 75, 76, 76, 79, 83, 86
Then, cross off each number at each end until you reach the one in the middle. Which, since they are the same, is 76.

1. This question is asking for the dilation, or division of each point by a factor of 3. This is shown in the results below:
A' = (-4/3, -2/3)
B' = (1/3, -1)
C' = (2/3, -5/3)
D' = (-1/3, 7/3)
2. This question is asking the same thing as the previous question except for new points and a new scale factor. The results are shown below:
A' = (3, 1)
B' = (-2, -2)
C' = (-4, 6)
D' = (1, -4)
3. This question is basically asking to multiply the area of the fence by two as shown with "extend the fence's range by a scale factor of 2." The results are shown below:
A' = (4, 6)
B' = (-6, 4)
C' = (4, -4)
4. This question is asking for the ratio of each side. Moreover, this means that the same side on both triangles must equal the same ratio. This is shown below:
75/24 = 25/8
60/18 = 10/3
The values of 25/8 and 10/3 are not the same, meaning that the scale ratio is not the same. These two triangles are NOT similar because of this.
5. This question is asking the same thing as question 4. The results are shown below:
10/5 = 2
10/5 = 2
As these values are the same, these two triangles ARE similar because of how the larger triangle is multiplied by a scale factor of 2.

Answer:
∠ADE = 59°
Step-by-step explanation:
4x + 15° + 13x + 7° = 90°
combine like terms:
17x + 22° = 90°
subtract 22° from both sides of the equation:
17x = 68°
divide both sides by 17:
x = 4
∠ADE = ∠CBD = 13(4) + 7 = 59°
Answer:
m∠ADE = 59°Step-by-step explanation:
m∠ADE is the same as m∠BCE, so
m∠ADE = (13x+7)°
In rectangle all angles are 90°, so:
4x + 15 + 13x + 7 = 90
17x + 22 = 90
17x = 90 - 22
17x = 68
x = 68÷17 = 4
Therefore:
m∠ADE = (13×4+7)° = 59°

David made a batch of 5 liters of blue liquid everyday for 3 days how many milliliters of blue liquid did he make in all
Answer: 15000 millimeters
Step-by-step explanation:
Since David David made a batch of 5 liters of blue liquid everyday. The number of liters that'll be made for 3 days will be:
= 5 liters × 3
= 15 liters
We should note that 1000 millimeters = 1 liter. Therefore, 15 liters will be converted to millimeters which will be:
= 15 × 1000
= 15000 millimeters
. A movie company sells DVDs on line. Each
DVD costs $9.95. No matter how many you
order, the shipping charge is $3.59. Your most
recent order came to a total of $33.44.
Please help on all questions in picture
Multiply by cost of a dvd by the number of dvds bought ( x) and add the shipping charge.
A) 33.44 = 9.95x + 3.59
Subtract 3.59 from both sides.
29.85 = 9.95x
Divide both sides by 9.95
X = 29.85/9.95
X = 3
They bought 3 dvds.
B) 33.49-3.59 = 29.85
29.85/9.95 = 3
C) the steps were the same but solving arithmetic you didn’t have to do steps on both sides of an equation.

15 chocolate were distributed between raju and sanju in the ratio 2:3 . How many chocolates did raju receive?
Answer:
6chocolates
Step-by-step explanation:
Given
The total number of chocolate = 15chocolates
If it is divide into ratio 2:3
total ratio = 2+3
Total ratio = 5
Number of chocolate raju receives = 2/5 * 15
Number of chocolate raju receives = 2 * 3
Number of chocolate raju receives = 6chocolates
The number of chocolates that Raju received are; 6 chocolates
ProportionWe are told that;
Number of chocolates distributed = 15
Ratio of sharing between Raju and sanju = 2:3
Thus, fraction to be received by both of them are;
For Raju = 2/(2 + 3) = 2/5For Sanju = 3/(2 + 3) = 3/5Thus;
Amount of chocolates for Rajus = 2/5 × 15 = 6
In conclusion, Raju received 6 chocolates.
