Answer:
6/7 = 36/42
12/8 = 30/20
Step-by-step explanation:
(6*?) / (7*6) = ?/42
(6*6) / (7*6) = 36/42
(12*2.5) / (8*?) = 30/?
(12*2.5) / (8*2.5) = 30/20

Sebastian was driving down a road and after 4 hours he had traveled 98 miles. At this
speed, how many hours would it take Sebastian to thrive 245 miles?
Fill out the table of equivalent ratios until you have found the value of x.
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.

6x+10=30x+135 solve for "x"
Answer:
x=-125/24
Step-by-step explanation:
(6x+10)+(-10-30x)=(30x+135)+(-10-30x)
(6x+10)+(-30x-10)=(30x+135)+(-30x-10)
6x+10-30x-10=30x+135-30x-10
6x-30x+10-10=30x-30x+135-10
-24x=125
24x/24=-125/24
x=-125/24

sam currently has $150 in a savings account and is saving 10$ per week. write an equation
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.
What is Equation?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.

7x - 3 > 18 or 3x – 25-2
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 :)

Step-by-step explanation:
An auditorium has 300 seats.at the beginning of a concert,100 people were in the auditorium.every 10 minutes,15 people leave and 40 people sit down.if this continues,how long will it take for the auditorium to be full?
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

x = 3.5
x = 0.1
x = 4
x = 20
(In order top to bottom)

2(x) = 7
/2 /2
x = 3.5 (1st one)
60(x) = 6
/60 /60
x = 0.1 (2nd one)
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
