On a certain hot summer's day, 218 people used the public swimming pool. The daily prices are $1.25 for children and $2.00 for adults. The receipts for admission totaled $349.75.
How many children and how many adults swam at the public pool that day?
Answers
Answer:
We call x the number of children and y the number of adults
We have system of equations
x + y = 218 (1)
1.25x + 2y = 349.75 (2)
(1) => x = 218 - y. Replace x in (2) 1.25 (218-y) + 2y = 349.75
=> y = 103 replace y in (1) x = 218-103 = 115
Children and how many adults swam at the public pool that day is : 115 and 103

Algebraic representation is (x, y) → (kx, ky), and it is by 1/3 because -3 is 1/3 of -9 and -4 is 1/3 of -12.
Evaluate the expression when g=3 and h= 17
h−5g
Answers
EXPLANATION:
If g= 3 we can replace g with 3.
Now we have h-5 x 3
and if h= 17, we can replace h with 17.
Now we have 17 - 5 x 3.
because of pemdas, multiplication is first
5 x 3 is 15,
17 - 15 is 2.

which of the following results in the difference of two squares?
a. (4x-5y)(4x+5y)
b. (5x+3y)(5x+3y)
c. (2x-3y)^2
d. 4x^2(3x-9)
Answers
Answer:
The answer is a.
Step-by-step explanation:
Observe the formula: [tex](a+b)(a-b)=a^2-b^2[/tex]
A is the only one that has this format. Thus, it is the difference of two squares.
The results in the difference between the two squares are (4x-5y)(4x+5y). then the correct answer is option A.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Use the algebraic identity a² - b² = ( a + b ) ( a - b ).
Let a = 4x and b = 5y, two sides of the square now the difference will be calculated:-
a² - b² = ( a + b ) ( a - b ).
(4x)² - (5y)² = ( 4x + 5y ) ( 4x - 5y ).
Hence, the correct answer is option A.

is 6y-27 and 3(3y-9) equivalent or not?
Answers
Answer:
No
Step-by-step explanation:
These two expressions are not equivalent. They are not equivalent, because when you solve the second one, to put it into its simpler form, you have to distribute the 3 out to 3y and -9, which you would get 9y-27. And 9y-27 is not 6y-27, they have different y values. I hope this helps :)
The odometer in a car measures the number of miles driven by the car since it was made. During a trip, the odometer reading in Anita’s car is modeled by the function y=9500+55x, where x represents the number of hours driven during the trip and y represents the odometer reading in miles.
Part A
What is the meaning of the rate of change in this function?
The number of miles driven each hour during the trip.
The total number of miles driven at the beginning of the trip.
The total number of miles driven at the end of the trip.
The number of miles driven during the trip.
Question 2
Part B
What was the odometer reading, in miles, before Anita’s trip?
Answers
Answer:
Step-by-step explanation:
Part A
The units on 9500 must be miles. So if x is time, then 55 must be the rate at which she travels ie 55 miles per hour. So the answer must be A.
Part B
The trip began when the time was zero. Therefore x is zero. What remains is the mileage on the odometer when x = 0. The answer must be 1950.

The area of a rectangular
driveway is 2x2 + 15x + 25.
The width of the driveway is
x + 5. What is the length of
the driveway?
Answers
Answer:
2x+5
Step-by-step explanation:
Okay so lets first factor 2x^2+15x+25
2*25=50
10+5=15
10*5=15
(x+10/2)(x+5/2)
=(x+5)(2x+5)
we know that the width is x+5 so that means the length has to be 2x+5
