[tex] \frac{5x - 2}{2} = 9[/tex]​

Answers

Answer 1

Answer:

x = 4

Step-by-step explanation:

[tex]\frac{5x -2 }{2} = 9 \\[/tex]

Cross multiply,

5x - 2 = 9*2

5x - 2 = 18   {Add 2 to both sides}

    5x = 18 +2

   5x = 20        {Divide both sides by 5}

     x = 20/5

   x = 4

You and your friend were working the ticket table at the last school basketball game.
The tickets sold for $5 for adults and $3 for students.
A total of 375 people attended the
game and a total of $1375 was taken in at the ticket table. How many adult tickets were
sold and how many student tickets were sold?

Answers

Answer:

Step-by-step explanation:

First

a+s=375

a=375-s

Next

5a+3s=1375, now using a found above makes this equation become

5(375-s)+3s=1375

1875-5s+3s=1375

1875-2s=1375

-2s=-500

s=250, since a=375-s

a=375-250

a=125

So 125 adult and 250 student tickets were sold.

Jason purchased 12 shirts for the members of a school club. Each shirt cost $5.50. Jason
had a coupon for 25% off his total purchase. Sales tax was 6.0% after the discount. What
was the total cost for the shirts? (Write your answer to the Hundredths Place, DO NOT
USE A $ Sign)
The total cost was type your answer.
dollars.

Answers

Answer:

52 dollars and 47 cents, or 52.47

Step-by-step explanation:

First, multiply 12 and 5.50, then you should get 66.00. Then, take the 25% discount, and divide it by a hundred, you should get 0.25, now multiply 0.25 and 66.00. You should get 16.50, thats your discount, so subtract 16.50 from 66.00, you should get 49.50. Now for the sales tax, divide 6.0 by 100, you should get 0.06. Now multiply 0.06 and 49.50, you should get 2.97, thats your tax, add it to 49.50, and you get 52.47 so BOOM, thats your answer, your welcome

Step-by-step explanation:

9)m−18≤36

Add 18 to both sides.

m≤36+18

Add 36 and 18 to get 54.

m≤54

11)9x>270

Divide both sides by 9. Since 9 is positive, the inequality direction remains the same.

x=270/9

Divide 270 by 9 to get 30.

x>30

13)y/5≤8

Multiply both sides by 5. Since 5 is positive, the inequality direction remains the same.

what is the mean, median, mode and range of 7, 2, 1, 4, 1

Answers

The mean is the total of all the values, divided by the number of values. To find the mean, we add up all the results and then divide them by the total number of values which is 5:

1 + 1 + 2 + 4 + 7 = 15

15 / 5 = 3.

The median is the middle number in a list of numbers ordered from smallest to largest, so the median is 2.

1, 1, (2), 4, 7

The mode is the value that appears most often in a set of data. In this case, the mode is 1.

1: 2
2: 1
4: 1
7: 1

The range is the difference between the highest value and the lowest value, so the range here is 6.

Highest value: 7
Lowest value: 1

7 - 1 = 6

Number of strikeouts per inning if there were 54 strikeouts in 27 innings.

Answers

Answer:

$31 per ticket

$0.33 per volleyball

2 strikeouts per inning

Step-by-step explanation:

Price per ticket:

279 = 9x

Divide both sides by 9

31 = x

Price per volleyball:.

6 = 18x

Divide both sides by 18

6/18 = x

Both the numerator and denominator have a common factor of 6

6 ÷ 6 / 18 ÷ 6 = x

1/3 = x

Convert to decimal for money

0.33 = x

Number of strikeouts per inning:

54 = 27x

Divide both sides by 27

2 = x
