Sean and Evan are selling rolls of wrappign paper to raise money for new football uniforms. Evan has sold seven more than one-half the number of rolls that Sean has. If they have sold a total of 121 rolls, how many has Evan sold?
x - Rolls sold by Evan

Answers

Answer 1

Let x be the number of rolls sold by Sean.

We are given that Evan has sold 7 more that one-half the number of rolls that Sean sold.

Evan has sold 1/2x + 7 rolls.

Therefore, we have:

x + (0.5x + 7) = 121

1.5x = 121 - 7

x = 114/1.5

x = 76

It is 15.4 I solved it

Answer:

15.4

Step-by-step explanation:

What i did was i did it in standard form. But, what i did was the 7 x 2 which is 14 then carried the 1 to the ones place. Then, i did 7x2 + 1 to get 15. Then, i did 0 x 2 and 2 x 0 to get 0, then i added and moved the decimal from 2.2 one time to make it 15.4. To check my work, i did 15.4 divided by 7 to get 2.2.

A restaurant sells burritos for $8.00 each. The cost of the meat is $1.50 and the cost of the other ingredients is $1.00 for each burrito.

Money made from selling burritos is positive. The cost of making burritos is negative. Profit is the money left after paying the costs.

How much profit would the restaurant make by selling 100 burritos?

1. How much money would the restaurant take in by selling 100 burritos?

2. What is the cost of making one burrito? (remember that costs are negative)

3. What is the cost of making 100 burritos?

4 What is the profit the restaurant makes from selling 100 burritos? Does the restaurant make money or lose money?

Answers

First let's find the cost to make the burritos.

$1.50 + $1.00 = $2.50 needed to make one burrito.

1. To find how much money the restaurant takes in from selling 100 burritos, we can do 100*8.00 which is $800.

2. We have already found the cost of making a burrito, which is $2.50

It says to convert the cost to a negative so I guess it would be -2.50?

3. The cost of making 100 burritos can be found by doing 100*2.50 which is equal to $250. The cost of making 100 burritos is $250.

4. To find the profit, we can subtract the answers from question 1 and question 3. 800-250 would be a profit of $550. The restaurant is gaining money. The price to make the burritos is way less than the money made from selling the burritos.

1. 550 becuase they make a 8 dollar profit, but then they lose 2.5 because to make the burito, they need to buy 1.5 dollars of meat and 1 dollar of ingredient. you get 8-2.5=5.5
then 5.5 times 100 because 5.5 is the amount gain after one burito. you want to find 100 so 5.5 times 100=550
2.-2.5
3.-2.5 times 100=-250
4. resturant makes money, they earn an 550 as said in the first question

What is the equation of the line that passes through (0, 3) and is perpendicular to y = = x + 5?
5

Answers

when you're doing a perpendicular line, you want the exact opposite of your original.

take, for example, a line with a slope of 2. the line perpendicular to it would have a slope of -2.

With a fraction, its pretty tricky. Let's say you have 2/7 as your slope. you want the EXACT opposite so

First, make it negative

Next, flip it around.

You get -7/2 as your slope perpendicular to your original line.

For the point passing through, if x equals 0, y equals your y intercept. your y value is 3 therefore b (y-intercept) equals 3.

For questions that are less simple than a plain y-intercept, (which you are guaranteed to encounter in the future) you simply input the y and x values into your y=mx+b equation.

Say we have an example here of a line with a slope of 4, and it passes through (5,-3). We have to find our B, or y-intercept, so we input the values.

-3=4(5)+b

Now, simplify

-3=20+b

-23=b

Your example equation is now y=4x-23

I hope this helped! please let me know if you have any questions! :)

She collects data on the number of turkey sandwiches sold per day for a week. Explain to her how to find the mean, median, mode, and range of the number of turkey sandwiches sold. How that would be helpful when she orders new turkey sandwich makings? Which measure do you think would be the most helpful for her and why?

Answers

Answer:

In order to find the mean of the sandwich shop you would add all of them up so 73+88+85+88+99+134+129 = 696. Then you divide it by how many days there are which there are 7 days so 696÷7=99.43. To find the median order the number least to greatest, then u count how many numbers are in the set. Count inwards and the median would be 88. The mode is the set of number that is in the problem the most, so in this case the mode would be 88. In order to find the range you subtract the highest number from the lowest number, so 134-73. The range would be 61. The measure that would be most helpful is the median, because it is not affected by the outliers!!

Answer:

It is 0.23 with the 23 repeating. The decimal repeats when he divided into the same number twice.

Step-by-step explanation:

23÷99=0.232323232

Since 0.232323232 is a repeating decimal with the 23 repeating, it can be represented as 0.23 with the line over 23

If we choose to eliminate x, multiply the first equation by -3: -15x - 6y = 3

and multiply the second by 5: -15x - 35y = 55

Note that this allows us to eliminate x. We get:

-6y = 3

-35y = 55

which sum up to -41y = 58. Thus, y = -58/4.

What is prime factorisation?

Prime factorisation is a method to find the prime factors of a given number, say a composite number. These factors are nothing but the prime numbers. A prime number is a number which has only two factors, i.e. 1 and the number itself. For example, 2 is a prime number which has two factors, 2 × 1.

With those already given, you need only plug them in to the formula:

Step-by-step explanation:

I just use y = mx + b

x and y are the coordinates and m is the slope of the line (you could find the slope of a line by using rise over run or (y2 - y1) over (x2 - x1)) The y-intercept or b is the point where the line hits the y axis.

what is 159,095 rounded to the nearest hundred?

Answers

Answer:

159,100 is the answer

Step-by-step explanation:

159,100 is the answer because 159,095 is closest to 159,100 than 159,000. So therefore, 159,100 is the answer.

Answer:

159,100

Step-by-step explanation:

200,000 - rounded to the nearest hundred thousands

160,00 - rounded to the nearest ten thousands

159,00 - rounded to the nearest thousands

159,100 - rounded to the nearest hundreds

159,100 - rounded to nearest tens

159,095 - rounded to nearest ones

While rounding off to the nearest hundred, if the digit in the tens place is between 0 – 4 i.e. < 5, then the tens place is replaced by ‘0’.

If the digit in the units place is equal to or >5, then the tens place is replaced by ‘0’ and the hundreds place is increased by 1.
