Answer:

x = 3.5

x = 0.1

x = 4

x = 20

(In order top to bottom)

Step-by-step explanation:

2(x) = 7

/2     /2

x = 3.5 (1st one)

60(x) = 6

/60    /60

x = 0.1 (2nd one)

12(x)=48

/12    /12

x = 4 (3rd one)

1/20(x)=1

x20    x20

x = 20 (4th one)

Equations:

1. 2 • x = 7

2. 60 • x = 6

3. 12 • x = 48

4. x • 1 over 20 = 1

Value of x (Answers):

1. 3.5

2. 0.1

3. 4

4. 20

Explanations:

For number 1;

7 ÷ 2 = 3.5

3.5 • 2 = 7

Therefore, 3.5 is your answer for number 1.

For number 2;

6 ÷ 60 = 0.1

0.1 • 60 = 6

Therefore, 0.1 is your answer for number 2.

For number 3;

48 ÷ 12 = 4

4 • 12 = 48

Therefore, 4 is your answer for number 3.

For number 4;

1 over 20 = 0.05

1 ÷ (1 over 20) = 20

20 • 1 over 20 = 1

Therefore, 20 is your answer for number 4.

Hope I made it clear for you, have a nice day!!! (I'm sorry that I am 4 months late.)

Answer:

Let x = speed for the first 96 miles

x - 9 = speed for the last 100 miles

Distance = (rate)(time), so time = (distance)/(rate)

(time for first part of trip) + (time for last part of trip) = 4 hours

So, (96)/(x) + (100)/(x - 9) = 4

Multiply both sides by the LCD (x)(x - 9) to get

96(x - 9) + 100x = 4x(x - 9)

96x - 864 +100x = 4x2 - 36x

4x2 - 232x + 864 = 0

Divide both sides by 4 to obtain x2 - 58x +216 = 0

(x - 4)(x - 54) = 0

x = 4 or x = 54

Note that x can't equal 4 because, in that case, x - 9 would be negative, so x = 54 miles per hour.

Answer:

Step-by-step explanation:

The auditorium will be full after 80 minutes

The total number of seats in the auditorium is the sum of all the people in the auditorium when it is full

Total number of people in the auditorium = 300

Every 10 minutes,15 people leave and 40 people sit down

Number of people joining the room every 10 minutes = 40 - 15

Number of people joining the room every 10 minutes = 25

The number of people originally in the room = 100

Number of people remaining for the auditorium to get full = 300 - 100

Number of people remaining for the auditorium to get full =  200

Number of times 25 people join the auditorium = 200/25

Number of times 25 people join the auditorium = 8

Since 25 people join every 10 minutes for 8 different times:

Time taken for the auditorium to be full = 10(8)

Time taken for the auditorium to be full = 80 minutes

Therefore, the auditorium will be full after 80 minutes

Hi I hope you are having a great day :) Your question, 7x - 3 > 18 or 3x – 25-2,

Let's solve your inequality step-by-step.

7x−3>(18)(3)x−25−2

1.  Simplify both sides of the inequality.

7x−3>54x−27

2.  Subtract 54x from both sides.

7x−3−54x>54x−27−54x

−47x−3>−27

3.  Add 3 to both sides.

−47x−3+3>−27+3

−47x>−24

4.  Divide both sides by -47

Finally answer, x<24/47

Hopefully that helps you :)

Answer:

$850

Step-by-step explanation:

you multiply 7 x 100 because there are 7 days in 1 week. That equals 700 plus 150 equals 850

Sam currently has $150 in a savings account and is saving 10$ per week. equation  y=150+10x represents the situation.

Two or more expressions with an Equal sign is called as Equation.

Given, sam currently has $150 in a savings account and is saving $10 per week.

The total amount of savings in dollars is represented by y.

x represents the number of weeks

The equation y=150+10x.

y equal to one hundred and fifty plus ten times of x.

Hence, Sam currently has $150 in a savings account and is saving 10$ per week. Equation  y=150+10x represents the situation.
