Brittany had 7 rolls of quarters and four extra quarters. She use the equation n = 7q + 4 to n, the number of quarter she had all together. What equation could she use to find q, the number of quarters in each roll?

Answers

Answer 1

She would use n-4=7q to find how many quarters in each roll.

Answer 2

Brittany can use the equation q = (n - 4) / 7 to find the number of quarters in each roll, based on the total number of quarters she has.

To find the equation that Brittany could use to determine the number of quarters in each roll (q), we can rearrange the original equation to solve for q. Given the equation n = 7q + 4, where n represents the total number of quarters she had, we can solve for q as follows:

n - 4 = 7q, by subtracting 4 from both sides of the equation.

Then, we divide both sides by 7 to isolate q:

q = (n - 4) / 7.

This equation can be used by Brittany to determine the number of quarters in each roll based on the total number of quarters she possesses. It essentially divides the total number of quarters minus the extra quarters by the number of rolls to give the quantity of quarters in each roll.

25% of all the seats in the auditorium is 37 shares the total number of seats in the auditorium is

Answers

The number of seats in the first row is 18;
The number of seats in the second row is 18+2=20;
The number of seats in the third row is 18+2*2=22;
The number of seats in the fourth row is 18+3*2=24;
...
The number of seats in the nth row is 18+(n-1)*2.

Notice that if we knew the total number of rows we would be able to sum the number of seats in each row and get the total number of seats.

(1) The number of rows of seats in the auditorium is 27. Sufficient.
(2) The number of seats in the last row is 70 --> 18+(n-1)*2=70, where n is the number of rows. We can get n. Sufficient.

A piece of carpet is 8 feet wide and 12 feet long. The carpet needs to be reduced by a scale factor so that the reduced carpet is 2 feet wide. What is the area of the reduced carpet

Answers

6 feet because 8 / 12 reduces to 2 / 3 and you multiply 2 times 3

Hi there.

So, we've got the dimensions.

l = 12, w = 8

We know that the width has been divided by 4. That means we also divide the length by 4. This gives us the new dimensions of:

l = 3, w = 2

A = lw

Carmen, Reuben, and Bob have a total of $133 in their wallets. Bob has 3 times what Reuben has. Carmen has $8 more than Reuben. How much does each have?

Answers

So you will want to form a few equations. The first one is:
C+R+B=133
Then you will want to form an equation for Bob:
B=3R
Then, another for Carmen
C=R+8

Knowing this information, you can plug each in, solving for R.

R+8+R+3R=133      Now Solve
5R+8=133               Subtract 8 from both sides
5R=125                   Divide 5 from both sides
R=25                       Now substitute R in for Carmen and Bob equations.

R=25                        Reuben has $25
C=8+25                    Add
C=33                        Carmen has $33
B=3(25)                    Multiply

A race car can travel 615 miles in 3 hour.A small jet can travel 575 miles in 2.5 hours.write and solve an equation to determine if the car or jet travels at a faster rate

Answers

car:
615/3= 205
the car travels 205 miles per hour.
jet:
575/2.5= 230
the jet travels 230 miles per hour.
the jet travels at a faster speed.

Final answer:

To compare the rates of travel of a race car and a small jet, divide the distance traveled by the time taken for each. The small jet travels at a faster rate than the race car.

Explanation:

To determine which travels at a faster rate, we need to compare their rates of travel. The rate of travel is found by dividing the distance traveled by the time taken. Let's denote the rate of the race car as 'r1' and the rate of the small jet as 'r2'.

For the race car, we have r1 = 615 miles / 3 hours = 205 miles per hour.

For the small jet, we have r2 = 575 miles / 2.5 hours = 230 miles per hour.

Comparing the rates, we see that the small jet travels at a faster rate than the race car.

You eat 3 8 of a pie and your sister eats 1 4 of the pie. Explain who ate more of the pie

Answers

First, you need to find a common denominator, you should get 2/8 and 3/8. So, you ate more of the pie

You ate more of the pie, the reason this is the case is because you ate 1.5 fourths of the pie. In order to solve these types of problems, you need to make the divisors of the amount of the pie you ate the same. in order to do this, we need to make 8 become 4, to do this we need to divide 8 by 2 which gives us four, remember what you do to the top of the fraction you MUST do to the bottom, which means that we need to divide the bottom by 2 which gives us 1.5.
We could also make the divisor of the fraction that expresses the amount of pie your sister ate 8 instead of making the other divisor 4. In order to do this, we must multiply 4 by 2 to give us 8, remember what we do to the top of the fraction you MUST do to the bottom, so we multiply the bottom by 2 giving us 2/8. You ate 1.5/4 and your sister ate 1/4 or your sister ate 2/8 and you ate 3/8. You ate more of the pie. I hope that this helped you out.

converting percent into decimals

Answers

To convert a percent to a decimal, you move the the decimal left two places to convert the percent to a decimal. For example, if you were to convert 14% to a decimal, you move the decimal left two places so that 14% converted to a decimal would look something like this: 0.14

Percent means per 100 so 40% 40 per 100, or simply 40/100

When we divide 40 by 100 we get 0.4 which is a decimal number.

to convert from percent to decimal you have to divide by 100, and then remove the % sign.

is the product of a fraction less than 1 and a whole number greater than or less than the whole number? explain

Answers

It depends, if the numerator is greater than the denominator, the product will be greater. If not, the product will be less than the whole number. If the fraction is equal to one,(ex. 2/2,50/50,-2/-2), then it would be equal.

Multiplying a fraction less than 1 with a whole number produces a result that is less than the original whole number because you are taking a portion of it.

The product of a fraction less than 1 and a whole number is always less than the original whole number. To understand why, consider the fraction as a part of the whole. If you multiply the whole by a part less than the whole (a fraction less than 1), you're essentially taking only a portion of it, which must logically be smaller than the whole itself.

120% of 33 is what number?

Answers

Change 120% into a decimal using the DP rule. D stands for decimal and P stands for percent. If you are trying to change a percent into a decimal then move the decimal spots two spaces to the right, but if you are changing a decimal into a percent then you move the decimal two spaces to the right. In this case we have to move the decimal two spaces to the left. Imagine in a percent that there is an imaginary decimal on the right of the 0 in 120 so when you move the decimal to the left it will become 1.20. Now multiply 1.20 and 33 which should give you an answer of 39.6 .
