You made two deposits to your bank accounts this month. One deposit was $17.92, and the second deposit was $15.33. Your balance at the end of the month is $72.31, and you made no withdrawals. Which expression shows your balance at the beginning of the month?
Answers
$72.31 is the total amount AFTER ADDING TWO DEPOSITS

So each bouquet is $3 if she buys 40 bouquets for $120
Therefore 40 bouquets for $2.50 each is less expensive

The Kendras error is that she doesn't know multiplication.
What is multiplication?Multiplication is the general procedure in mathematics in which we multiply two or more numbers to each other to find a new multiplied number.
Multiplication gives us a resultant number that will be very big as compared to the number which is going to be multiplied if and only if the number which is going to be multiplied is more than one.
Given that Kendra buy 40 bouquets for $120
So each bouquet cost 120/40 = $3 so each bouquet cost $3.
By the second option, she will get bouquets at $2.50 only it is an error of Kendra.

Liam and Harper are racing on a track. Liam runs 4 miles per hour and gets a 0.25 miles head start. Harper runs 0.5 mile per hour faster than Liam. If Harper and Liam run the same distance, how many hours, x, do they run.
Answers
The time 'x' that both Harper and Liam are running for is 0.25 hours. This is calculated by setting the total distance covered by both runners equal to each other and solving for 'x'.
Explanation:The subject of your question is Mathematics, specifically dealing with concepts of race pacing and distance calculations. Here's an answer to your question:
Let's denote the time it takes for both Harper and Liam to finish the race as 'x' hours. Given that Liam runs at 4 miles per hour and has a 0.25-mile head start, the total distance he runs is 4x + 0.25 miles. Harper, on the other hand, runs at 4.5 miles per hour (0.5 mile per hour faster than Liam) for 'x' hours, so Harper runs a total of 4.5x miles.
Since both runners run the same total distance, we can set these two equations equal to each other and solve for 'x':
4x + 0.25 = 4.5x
Solving this equation gives x = 0.25 hours.

find two consecutive integers whose sum is 45
Answers
____________________________________________________
x + (x + 1) = 45 ;
in which:
"x" is the first integer (of the 2 consecutive integers) ;
"(x + 1)" is the second integer (of the 2 consecutive integers);
_______________________________________________________
We want to solve for "x";
which is the first integer (of the 2 consecutive integers);
then we can solve for the second integer (of the 2 consecutive integers);
as well;
_______________________________________________________
We have:
_______________________________________________________
x + (x + 1) = 45 ;
Rewrite as:
x + x + 1 = 45 ;
↔ 1x + 1x + 1 = 45 ;
→ 2x + 1 = 45 ;
Subtract "1" from each side of the equation;
2x + 1 −1 = 45 − 1 ;
to get:
2x = 44 ;
Divide EACH SIDE of the equation by "2" ; to isolate "x" on one side of the equation; and to solve for "x" ;
______________________________________________
2x / 2 = 44 / 2 ;
to get: x = 22 ;
______________________________________________
Our two consecutive integers:
x = 22 ;
(x + 1) = 22 + 1 = 23 .
______________________________________________
The two consecutive integers are: "22" and "23" .

Let us check our answer:
Are "22" and "23" consecutive integers? Yes!
Do "22" and "23" add up to "45" ? ;

Annette is surveying people in the city about their interest in a new shopping mall. She found that 180 people, or 37.5% of those surveyed do not want a new mall. How many people did Annette survey?
Answers
Answer:
480 people
Step-by-step explanation:
First you would divide 180 by 37.5,
180 divided by 37.5 = 4.8
Then you multiply 4.8 with 100
4.8 times 100 =480
Therefore, Annette surveyed 480 people
We want to find the total number of people that Annette surveyed given that we know a percentage and the number that the percentage represents.
We will find that the number of people that Annette survey is 480.
To get the solution:
Let's assume that she surveyed a total of X people.
Then we can write the equivalence:
100% = X
We know that the 37.5% is equivalent to 180 people, then we can write:
37.5% = 180
The two equations are:
100% = X
37.5% = 180
Now we can take the quotient between these two equations to get:
(100%/37.5%) = X/180
Solving for X we get:
(100%/37.5%)*180 = X = 480
So the total number of people surveyed is 480.

Answers
-7.5 x + 22.5 = 3.75
-7.5 x = - 18.75
x = 2.5

Answer: The required value of x is 2.5.
Step-by-step explanation: We are given to find the value of x in the following equation :
[tex]-7.5(x-3)=3.75~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
To find the value of x, we need to solve the given equation (i).
The solution of equation (i) is as follows :
[tex]-7.5(x-3)=3.75\\\\\\\Rightarrow x-3=\dfrac{3.75}{-7.5}\\\\\\\Rightarrow x-3=-0.5\\\\\Rightarrow x=3-0.5\\\\\Rightarrow x=2.5.[/tex]
Thus, the required value of x is 2.5.
Kate's golf score was 1 less than three fourths of Greg's golf score. If the sum of their scores was 153, find Kara's hold score.
Answers
Answer: Kate's score is 65.
Step-by-step explanation: Given that Kate's golf score was 1 less than three fourths of Greg's golf score and the sum of their scores was 153.
We are to find Kate's score.
Let x and y represents Greg's score and Kate's score respectively.
Then, according to the given information, we have
[tex]y=\dfrac{3}{4}x-1~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
and
[tex]x+y=153\\\\\Rightarrow x+\dfrac{3}{4}x-1=153\\\\\\\Rightarrow \dfrac{7}{4}x=154\\\\\Rightarrow \dfrac{x}{4}=22\\\\\Rightarrow x=22\times4\\\\\Rightarrow x=88.[/tex]
From equation (i), we get
[tex]y=\dfrac{3}{4}\times88-1=66-1=65.[/tex]
Thus, Kate's score is 65.
The viewership of a television show has decreased form 5.1 million viewers to 3.5 million viewers per episode. Find the percent of decrease in viewership to the nearest percent.
Answers
Final answer:
To calculate the percent decrease in viewership, subtract the final number of viewers from the original number, divide that by the original number, and multiply by 100, rounding to the nearest percent. The viewership decreased from 5.1 million to 3.5 million, a 31% decrease.
Explanation:
The subject of this question is Mathematics, specifically relating to percentages. To find the percent decrease in viewership from 5.1 million to 3.5 million:
Calculate the decrease in viewers: 5.1 million - 3.5 million = 1.6 million.
Find the percentage: (1.6 million / 5.1 million) × 100 = 31.37%.
Round to the nearest percent: 31.37% ≈ 31%.
Therefore, the viewership has decreased by approximately 31%.
