Ahmad bought 4 CDs that were each the same price. Including sales tax, he paid a total of 57.60. Each CD had a tax of 1.10, What was the price of each CD before tax?

Answer:

12

Step-by-step explanation:

17 - 10 = 7

what plus 10 equals 17?

7

so if know C is 7 we do,

7+5=?

if you count on your hands

7, 8, 9, 10, 11, 12

so in conclusion,

7+5=12

the answer is

balanced in

Answer:

Blank one could be 4

Blank three should be 12

Step-by-step explanation:

Answer:24% error

Step-by-step explanation:

subtract the estimate and the cost

93,000-75,000

=18000

divide the cost and the subtracted sum you just got

=[tex]\frac{18000}{75000}[/tex]

cross out the common factor

=[tex]\frac{6}{25}[/tex]

Multiply a number to both the numerator and denominator (easier if you multiply the number that makes the denominator 100)

[tex]\frac{6}{25} x\frac{4}{4}[/tex]

=[tex]\frac{24}{100}[/tex]

write the fraction as a percentage

=24%

Answer:

Determine whether a number is a solution to an equation.

Substitute the number for the variable in the equation.

Simplify the expressions on both sides of the equation.

Determine whether the resulting equation is true. If it is true, the number is a solution. If it is not true, the number is not a solution.

Answer:

n = 10

Step-by-step explanation:
If n is next to 0.8 that means its multiplying by whatever n is and if you do 0.8 x 10 it equals to 8

Answer: n=10

Step-by-step explanation:

0.8n = 8 First step is to divide each step by 0.8 to isolate the variable

8/0.8 Next you divide 8 by 0.8 to get your answer

The answer would be 10.

To extra check your answer you can do the reverse and multiply.

0.8x10=8

So now you know for sure the answer is 10 ;-)

Answer:

ok so I'm not gonna do em but I will explain how to find mean, median, mode and range

Step-by-step explanation:

starting of with mean: first you add all your numbers ex your first question: 61+98+60+60+57+81+93=510

secondly you devide the sum of all those values by how many values there are. there are 7 values so you would devide 510 by 7 ex: 510÷7= 72.9 (rounded by nearest hundredth)

finding the median: firstly you order all your values from least to greatest :ex w your first question again: 61,98,60,60,57,81,93 ~ 57,60,60,61,81,93,98

secondly you find the middle number of what is in those values by deviding it into 2 and seeing what the middle would be. ex: 57,60,60, ⁶¹,81,93,98 our median is 61.

in the case there is 2 numbers in the middle ex number 10:23,30,35,52,55,55 ~ 23,30,³⁵,⁵²,55,55 you add those 2 middle values and devid by 2 basically find the mean ex: 35+53÷2= 61.5 that's your mean.

finding range: subtract lowest from highest value ex question 1: 98-57=41 your range is 41.

finding mode:Place all numbers in a given set in order; this can be from lowest to highest or highest to lowest, and then count how many times each number appears in the set. The one that appears the most is the mode.ex: 57,60,60,61,81,93,98 60 appears the most so it is the mode.

hope this helps I spent like 45 mins writing this

Answer:

1. Mean: 72.857 Median: 61 Mode: 60 Range: 41

2. Mean: 71.5 Median: 75.5 Mode: 94 Range: 76

3. Mean: 69 Median: 73 Mode: no mode Range: 36

4. Mean: 62.667 Median: 68.5 Mode: 31 Range: 66

5. Mean: 53.833 Median: 68.5 Mode: 13 Range: 72

6. Mean: 58 Median: 74 Mode: 22 Range: 71

7. Mean: 51 Median: 55 Mode: 55 Range: 68

8. Mean: 50.182 Median: 58 Mode: 11, 73 Range: 83

9. Mean: 43.714 Median: 45 Mode: 12 Range: 77

10. Mean: 41.667 Median: 43.5 Mode: 55 Range: 32

Step-by-step explanation:

How to find Mean: Add all the numbers together then divide by the number of numbers.

How to find Median: Place the numbers in value order and find the middle.

If odd, cross out the leftmost number, then the rightmost number, and then repeat. When you have one number left, this is your median.

If even, cross out numbers on either side, but you should have two numbers exactly in the middle. Add them together and divide by two for the median value.

How to find Mode:

Put the numbers in order, then count how many of each number. A number that appears most often is the mode.

How to find Range:

Order all values in your data set from low to high, then subtract the lowest value from the highest value.

Answer:

Unlikely is probably the answer.

Step-by-step explanation:

Because Likely would mean above 50%

Equally likely and unlikely would be (equally) so 50% exact.

The last option seems wrong.

So Unlikely makes the most sense

Answer: Z=14

Step-by-step explanation:

Simplify the equation: 1/4z=7/2

then multiple both sides by 4:

4 (1/4) = 4 (7/2)

z= 14

Answer: z=14

Step-by-step explanation: very easy

1/4z = 3 1/2 Divide each side by 1/4 to isolate z

3 1/2 will be divided by 1/4

How to divide 3 1/2 by 1/4?
Keep, change, flip.

First: Convert 3 1/2 to an improper fraction which is 7/2

Second: 7/2 / 1/4 keep 7/2

7/2 x 1/4 change from dividing to multiplying

7/2 x 4/1 flip 1/4 around to make it 4/1

28/2 multiply and then simplify to 14.

so the answer is 14

The value of 3(y+5) will be 75.

First, We need to solve the given linear equation y - 16 = 4 to find the value of y :

⇒ y-16=4

taking -16 to right side of the equation,

⇒y=4+16

⇒y=20

Now, we can put the value of Y in the 2nd equation 3(y+5):

⇒  3(y+5)

multiply both the terms  inside brackets from 3,

⇒ 3y + (3x5)

⇒3y + 15

now, put calculated value of y in the equation,

⇒3x20 + 15

⇒60  + 15

⇒75

∴ 3(y+5) = 75
