Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
First you have to translate the words to numbers into an understandable equation like this...
[tex]2x+3x=3(x+5)[/tex]
Now we can solve for x...
[tex]2x+3x=3(x+5)\\2x+3x=3x+15\\5x=3x+15\\2x=15\\x=7.5[/tex]
So the number is 7.5
5/2 is the number if the sum of twice a number and three times a number is triple the quantity of five more than a number then the number.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, The sum of twice a number and three times a number is triple the quantity of five more than a number.
Assuming the number has a unique multiple of x.
∴ 2x + 3x = (3x + 5).
2x = 5.
x = 5/2.

The Case of the Bogus $20 Bill
A customer goes into a shoe store and buys a pair of shoes for $5, but pays with a counterfeit $20 bill. The shoe store owner does not realize that the $20 bill is bogus. However, the shoe store owner notices that she does not have change for the $20 bill - so she runs to the grocer next door. The grocer gives the shoe store owner four $5 bills for the bogus $20 bill. The shoe store owner returns to her store and gives the customer the shoes and $15 change. Later the grocer arrives at the shoe store with the FBI to inform the owner that the $20 bill was bogus! So the shoe store owner is forced to give the grocer $20, and the FBI keeps the bogus bill. How much did the shoe store owner lose?

At a recent marathon, spectators lined the street near the starting line to cheer for the runners. The crowd lined up 5 feet deep on both sides of the street for the first mile. You estimate that 14 people can comfortably fit in a square that measures 5 feet by 5 feet. Using this information, how many people cheered for the runners at the start of the race? 1mile=5280 feet
Answer:
29568 people cheered for the runners at the start of the race
Step-by-step explanation:
From the question, the crowd lined up 5 feet deep on both sides of the street for the first mile.
This lined up crowd could be related to a rectangle that is 1 mile long and 5 feet wide.
First, Convert 1 mile to feet
1 mile = 5280 feet
Hence, the length of the rectangle is 5280 feet and the width is 5 feet.
Now, we will determine how many 5 feet by 5 feet square we can get from the 5280 feet by 5 feet rectangle. To do that, we will divide 5280 feet by 5 feet
5280 feet ÷ 5 feet = 1056
Hence, from the rectangle, we can get 1056 5 feet by 5 feet square.
From the question, you estimate that 14 people can comfortably fit in a square that measures 5 feet by 5 feet,
∴ 14 × 1056 people will comfortably fit in the crowed lined up 5 feet deep on one side of the street for the first mile.
14 × 1056 = 14784 people
This is the amount of people that will comfortably fit in the crowed lined up 5 feet deep on one side of the street for the first mile.
Since the crowd lined up on both sides of the street, then
2 × 14784 people will comfortably fit in the crowed lined up 5 feet deep on both sides of the street for the first mile
2 × 14784 = 29568 people
Hence, 29568 people cheered for the runners at the start of the race.

I need help finding the measure of the missing angles
Answer:
x = 61°
y = 29°
Step-by-step explanation:
Since x°+29° is a right angle (90°), you would have to subtract 29 from 90 to get x.
90 - 29 = x
90 - 29 = 61
x = 61°
For y: You can infer that y°+x°=90° as well because the angles are corresponding angles. So to find y°, you would do the same thing as finding x.
90 - x = y
90 - 61 = 29
y = 29°

You randomly draw a marble from a bag, record its color, and then replace it. You draw a red marble 9 out of 25 times. What is the experimental probability that the next marble will be red? Write your answer as a fraction, decimal, or percent.
The experimental probability that the next marble will be red is
.
Does it say how many of the marbles in the bag are red? Normally you will want to divide the amount of red marbles to the amount total marbles and you will get a percent. It's also note worthy that it states the marble going back into the bag. It would change if it was left out still.
Amari can spend at most $40 at the fair. It cost her $12 to enter the fair and $3 per ticket, t, to ride the rides.
Answer:
i have no idea if you're looking for how many rides she can go on or the equation so i'll give you both lol.
Step-by-step explanation:
3t + 12 = 40
t represents the number of tickets (rides)
$12 is the entry fee.
$3 is the cost per ticket
to solve, use the subtraction property of equality. (subtract 12 from both sides)
3t + 12 - 12 = 40 - 12
3t = 28
divide each side by 3.
3t/3 = 28/3
28/3 = 9.3333...
amari can go on a maximum of 9 rides ($27) and stay within her budget of $40 or less.
$27 + $12 = $39.
she will have $1 left over.
The inequality in the given situation is 3t+12≤40
Given that, Amari can spend at most $40 at the fair.
What is inequality?Inequalities are mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
Now, the cost her $12 to enter the fair and $3 per ticket, t, to ride the rides.
Here, $3 per ticket, t, to ride the rides = 3t
So, the inequality is 3t+12≤40
Therefore, the inequality in the given situation is 3t+12≤40.

The tens digit of a three digit number exceeds its units digits by 3. If we were to swap the 100's digit and the unit's digit, the new number would be 297 more than the original number. If we were to remove the hundreds digit from the original number, the two digit number obtained would be 13 less than half the original number. What's the original number?
Answer: 174
Step-by-step explanation:
Let's define the notation:
U = units digit
T = tens digit
H = hundreds digit.
Where the number is HTU.
We know that:
T = U + 3
"UTH" - "HTU" = 297.
"TU" = "HTU"/2 - 13.
First, let's wrote this correctly, and make a system of equations:
T = U + 3.
U*100 + T*10 + H - H*100 - T*10 - U = (U - H)*99 = 297.
T*10 + U = (H*100 + T*10 + U)/2 - 13 = H*50 + T*5 + U*0.5 - 13
Then we have the system of equations:
T = U + 3.
(U - H)*99 = 297
T*10 + U = H*50 + T*5 + U*0.5 - 13.
First, we can replace the first equation into the third one, so now we have only two variables.
(U - H)*99 = 297
(U +3)*10 + U = H*50 + (U + 3)*5 + U*0.5 - 13.
Now we can isolate H in the first equation and get:
(U - H) = 297/99
H = -297/99 + U.
Now we can replace it into the other equation:
(U +3)*10 + U = (-297/99 + U)*50 + (U + 3)*5 + U*0.5 - 13.
Now let's solve this for U.
U*10 + 30 + U = U*50 -150 + 5*U + 15 + U*0.5 - 13
11*U + 30 = U*(50 + 5 + 0.5) - 148
30 +148 = U*(55.5 - 11) = U*44.5
U = 178/44.5 = 4.
Then using the previous equations:
T = U + 3 = 4 + 3 = 7
H = -3 + U = -3 + 4 = 1.
Then our number is:
174.

find the three consecutive even intergers such that the sum of twice the smallest number and three times the largest is 42
Answer:
6, 8, 10.
Step-by-step explanation:
Let n be any integer.
Then our first even integer will be [tex]2n[/tex]
And the consecutive integers will be [tex]2n+2[/tex] and [tex]2n+4[/tex]
We want to find the integers such that the sum of twice the smallest number (2n) and three times the largest number (2n+4) is 42. In other words:
[tex]2(2n)+3(2n+4)=42[/tex]
Solve for n. Distribute:
[tex]4n+6n+12=42[/tex]
Combine like terms:
[tex]10n+12=42[/tex]
Subtract 12 from both sides:
[tex]10n=30[/tex]
Divide both sides by 10:
[tex]n=3[/tex]
So, the value of n is 3.
This means that our first even integer is 2(3) or 6.
So, our sequence of integers is: 6, 8, 10.
And we're done!
Notes:
We use 2n because anything integer multiplied by 2 ensures that the resulting number is even. Starting out, n can be either even or odd, but by multiplying it by 2, we will get an even number.
