Answer:
Given that the equation of the revenue is R=2x2+55x+10 and the equation of the cost is C=2x2 – 15x – 40, you will get the profit by subtracting the revenue from the cost: R-C=P. Therefore, P=(2x2+55x+10)-(2x2 – 15x – 40). You will get P=70x+50 where x is is the number of cellphones sold. If 240 cellphones are sold, then the profit is 16850 dollars.
Step-by-step explanation:
The profit expression is 70x + 50 and the profit if 240 cell phones are sold is $16,850
How to calculate profitRevenue, R = 2x² + 55x + 10Cost, C = 2x² – 15x – 40where,
x = number of cell phones sold.
Profit = Revenue - cost
= (2x² + 55x + 10) - (2x² – 15x – 40)
= 2x² + 55x + 10 - 2x² + 15x + 40
Profit = 70x + 50
If x = 240Profit = 70x + 50
= 70(240) + 50
= 16,800 + 50
= $16,850

Step-by-step explanation:
The angles of A and B are 45 degrees. This is true because the other angle is a right angle (90 degrees) and if you are making a triangle the degrees of the sides have to = 180 to be a complete triangle. The triangle is complete, so I took 180 – 90 = 90 ÷ 2 = 45.
The angle of C is 115 because it is a supplementary angle. A supplementary angle is an angle that has two angles with a sum of 180 degrees and 180 – 65 = 115

In a cafeteria, 1 10 of the students are eating salads , and 2 5 are eating sandwiches. There are 20 students in the cafeteria. How many students are eating lunches other than salads or sandwiches?
Answer:Number of students eating lunches other than salads or sandwiches= 10
Step-by-step explanation:
Number of students in the cafeteria=20
Number of students eating salads=1/10 X 20= 2
Number of students eating sandwiches= 2/5 x 20 = 8
Number of students eating lunches other than salads or sandwiches=
Number of students in the cafeteria -(
Number of students eating salads +Number of students eating sandwiches)

Answer:
(-5, -1)
Step-by-step explanation:
When two lines intersect, their x and y values are equal. So,
x = 3y - 2 must equal -7 - 2y = x
x = 3y - 2 = -7 - 2y = x
Let's look at the two middle equations and solve for y.
3y - 2 = -7 - 2y
Add 2y to both sides
5y - 2 = -7
Add 2 to both sides.
5y = -5
y = -1
Now, let's find x. You can use either equation for this step.
When y = -1, then 3y - 2 =
(3)(-1) - 2 = -3 - 2 = -5
So, x = -5, and y = -1
Thus, the answer is (-5, -1)

Every store employee gets an additional 10% off the already discounted price. If an employee buys an item with an original price of $40, how much is the discount? Explain how you got your answer
Answer:
$44.44444444
Step-by-step explanation:
So as per question employees get 10% discount of the discounted price. So our equation would be considering discounted price = x
=> x- 10x/100 = 40 => 100x-10x/100 = 40 => 90x = 4000 => x= $44.4444

B. Noah writes the equation 3 (x+7)=57 to represent the situation. DO YOU agree with him? Explain your answer.
Answer:
Yes , i agree with Noah that the equation would be 3(x + 7) = 57
Step-by-step explanation:
P.S - The exact question is -
To find - Noah writes the equation 3 (x+7)=57 to represent the situation.
DO YOU agree with him? Explain your answer.
Proof -
Yes , i agree with Noah
Because in the figure we can see that there is x written 3 times and 7 written 3 time and whole the values is equal to 57 .
Because 57 is divided into x 7 x 7 x 7
∴ we can write it as
3 times x + 3 times 7 = 57
⇒3(x) + 3(7) = 57
⇒3(x+7) = 57
Ans Noah give the same equation 3 (x+7)=57
So, I agree with Noah.
