15...?
Step-by-step explanation: Sorry if I got this incorrect...
Alex 15 arrows hit a target in all.
What are Arithmetic operations?Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.
Alex's first 10 all hit the target and earned him 20 more.
Now he has 20 and has used 10.
His next 5 hit the target and earned him 10 more.
He now has 25 (20–5+10) and has used 15.
All of the remaining 25 miss the target.
Alex had used a total of 40 arrows (25+15) and has hit the target 15 times.

He should have found the average of the number of rock songs by averaging 4 and 6 to get 5.
He did not multiply the numerator and denominator by the correct number to equal 1,500.
His answer will be one-half of what he got because he did not divide 10 by 2 when setting up the proportion.
He can only solve the proportion by multiplying the numerator and denominator by a common multiple.
He should have multiplied the numerator and denominator by 75, not 30, because 20 times 75 = 1,500.

What is the measure of angle 2 if angle 1 is (5x - 2) and angle 2 is (2x)?
Answers
Answer:
52 degrees
Step-by-step explanation:
We're given:
Angle 1 = 5x-2Angle 2 = 2xThe sum of the two angles is 180 degrees, because they construct a straight edge together. A straight line has an angle measure of 180 degrees.
Knowing this, we can form the following equation and solve for x:
\(5x-2+2x=180\\7x-2=180\\7x=182\\x=26\)
Therefore, x is 26. Find 2x to find the measure of Angle 2:
\(2*26=52\)
Therefore, Angle 2 has a measure of 52 degrees.
Answer:
52
Step-by-step explanation:
Angle 1 and angle 2 are on a straight line so their measure add up to 180 and they are supplementary
m<1 + m<2 = 180
5x - 2 + 2x = 180 add like terms
7x - 2 = 180 add 2 to both sides
7x = 182 divide both sides by 7
x = 26
To find the measure of angle 2 replace x with the value we found
m<2 = 2x
2*26 = 52
Angie and Kenny play online video games. Angie buys 1 software package and 2 months of game play. Kenny buys 1 software packages and 6 months of gameplay. Each software package costs $50. If their total is $250, what is the cost of one month of gameplay?
Answers
Answer:
$18.75 is the cost for 1 month of gameplay.
Step-by-step explanation:
2 software packages in total
Unit price for software package is $50, and since there are two packages, $50x2=$100
Now, we know that the total amount of money that the software cost was $100, we can do 250-100=150
150 is how much they spent for 8 months of gameplay. (2+6=8)
To find how much 1 month of gameplay costs, we need to do 150/8 which is equivalent to $18.75
18.75 is the cost of One month of gameplay

Today is my birthday! Four-fifths of my current age is greater than three-quarters of my age one year from now.
Given that my age is an integer number of years, what is the smallest my age could be?
NEED HELP ASAP
Answers
Answer:
For a second I thought your birthday was today haha.
Let's begin by creating an equation to reflect the supplied data.
Let x represent my current age.
We are aware of the following:
4/5 x > 3/4 (x + 1)
When both sides are multiplied by 20 (the least common multiple of 5 and 4) the result is:
16x > 15(x + 1)
When the right side is expanded, the following results:
16x > 15x + 15
Subtraction of 15x from both sides results in:
x > 15
My age cannot be less than 16 since it must be an integer number of years.
As a result, the answer is 16.

Sandy used a virtual coin toss app to show the results of flipping a coin 80 times, 800 times, and 3,000 times. Explain what most likely happened in Sandy's experiment.
Choice A: Sandy's experimental probability was exactly the same as the theoretical probability for all three experiments.
Choice B: Sandy's experimental probability was closest to the theoretical probability in the experiment with 80 flips.
Choice C: Sandy's experimental probability was closest to the theoretical probability in the experiment with 800 flips.
Choice D: Sandy's experimental probability was closest to the theoretical probability in the experiment with 3,000 flips.
Answers
As the number of coin flips increases, the experimental probability should get closer and closer to the theoretical probability. This is known as the law of large numbers. Therefore, it is most likely that Sandy's experimental probability was closest to the theoretical probability in the experiment with 3,000 flips, as this is the largest sample size. The correct answer is Choice D: Sandy's experimental probability was closest to the theoretical probability in the experiment with 3,000 flips.
What is 68/4+3- -3 help
Answers
Answer:
The answer is 23
Step-by-step explanation:
First, you need to divide 68 and 4, which will give you 17. Then, add 3. which will give you 20. Then add negative 3 and you should get 23.
Thank me later :)
Answer: 23
Step-by-step explanation: This is because 68 divided by 4 is 17 plus 3 which is 20 and the two negatives make the other 3 positive so add three and you get 23.

Which expression is equivalent to -1/3 ( 6x + 15 ) - 3?
a) -2x + 12
b) -2x + 2
c) -2x - 2
d) -2x - 8
Answers
The correct answer is (D) -2x - 8.
To simplify the expression -1/3 ( 6x + 15 ) - 3, we can first apply the distributive property to the term in parentheses:
-1/3 ( 6x + 15 ) - 3 = -1/3 * 6x - 1/3 * 15 - 3
Then we can simplify using the properties of multiplication and division:
-1/3 * 6x - 1/3 * 15 - 3 = -2x - 5 - 3
Finally, we can combine like terms:
-2x - 5 - 3 = -2x - 8
The correct answer is therefore (D) -2x - 8.✅

During a 20% off sale, the sale price of a microwave was $60. The sale has expired but Kristen has a coupon good for 15% off the regular price of any one item. How much will Kristen pay for the microwave before tax? Round to the nearest cent.
Answers
Answer:
it would take 9 dollar OFF!! so subtracted by 60 your welcome!!
(its 51 just saying.)
Step-by-step explanation:
x - 0.2x = 60
Simplifying the left side, we get:
0.8x = 60
Dividing both sides by 0.8, we get:
x = 75
So the regular price of the microwave is $75. Now, we can use Kristen's coupon to find the price she will pay:
Regular price = $75
Discount from coupon = 15%
Amount of discount = 0.15 x $75 = $11.25
Subtracting the discount from the regular price, we get:
Price after coupon = $75 - $11.25 = $63.75
Therefore, Kristen will pay $63.75 for the microwave before tax.

What is the cost per bracelet?

Answers
Answer:1. $3- 4 bottles, 1 bottle = 4/3 , 7 bottles= 28/3
2. 40 pounds=$32, 1 pound= $8/10
3. Per bag= 3/2, 7bags= 21/2
4. Per book = $3, 21 books= $63
5. Per bracelet = 0.25 cents, 11 bracelets = 2 dollars 75 cents
Step-by-step explanation:
It is 0.75 a bottle. We know that because 0.75 times 12 equals nine, so that checks our work.
7 bottles of water would cost 5.25 dollars because 0.75x7 is 5.25
Answer 2: 40 pounds would cost $32 because 10x4=40 so we can do $8x4= $32
It is 0.8 per pound. We know this because you divide 10 by 8 and it’s 0.8
Answer 3: It’s $1.50 per bag. We know that because $4 divided by 6 is $1.50.
At that rate, 7 bags would be $10.50. Because 1.50 times 7 equals 10.50.
Answer 4: it is 3 dollars per book. Because 15 divided by 5 is 3. At that rate we can buy 7 books because 7 times 3 is twenty one.
Answer 5: it is 0.25 per bracelet. We know this because 1 divided by 4 is 0.25. At that rate 11 bracelets will cost 2.75 dollars. We know this because 0.25 times 11 equals 2.75!
Hope this helps!
