This is the algebraic expression for "3 less than twice a number"
What is 2x - 3 ?
This is the answer to "4 less than 3 times a number is 11"
What is 5?
"4 less than 3 times a number is 11" is written in an equation as 3x - 4 = 11
If we are subtracting 4 FROM 3x a number to get 11, then adding 4 TO the number 11 would give us the actual 3x value
3x = 15
x = 5
Ben rented a car. It cost $20.00 plus $0.10 per mile. If Ben paid $50.00 for the car rental, how many miles did he drive the car?
Write an equation and then use your equation to find your answer.
$20.00 + $0.10m = $50.00 is the equation and
Ben drove 300 miles
Explanation:
$20.00 - $20.00 + $0.10m = $50.00 - $20.00
$0.10m = $30.00
$0.10m/$0.10 = $30.00/$0.10
m = 300

This is the expression for "the quotient of 3 times a number and 7"
What is 3x / 7 ?
The answer to "the quotient of a number and 7 is 63" is this....
What is 441?
"the quotient of a number and 7 is 63" can be written as x / 7 = 63
Since some number is being divided into 7 equal groups of 63, the actual number must be 7 times larger than 63
441 / 7 = 63
Sophia’s grandmother gave her $150 for singing lessons. She paid $10 for each lesson. How many lessons has she attended, if she still has $60 left. Write an equation and then use your equation to find your answer.
$10.00L + $60.00 = $150.00 is the equation and Sophia attended 9 lessons
Explanation:
$10.00L + $60.00 - $60.00 = $150.00 - $60.00
$10.00L = $90.00
$10.00L / $10.00 = $90.00 / $10.00
L = 9 Lessons

This is the expression for "2 less than the product of a number and 6"
What is 6x - 2 ?
What is the answer to "6 more than the product of a number and 12 = 90" ?
What is 7?
12x + 6 = 90
If we subtract 6 from 12x and 90, we would get that 12x = 84
x must be 7 because 7 times 12 = 84
12(7) + 6 = 90
84 + 6 = 90
90 = 90
Sierra sells books. This month she sold 580 books, which is 90 books more than she sold last month.
The equation to find how many books she sold last month AND the amount of books she did sell last month are this....
What is 580 - 90 = x or x + 90 = 580, or 580 -x = 90
and x = 490 books sold last month
Add up the number of times you see the letter "a" in the song "Its a small world after all" and multiply that by the number of times you see the letter "s" in the song "bare necessities" and you get this number....

Captain America, (Steve Rogers) is from Brooklyn. The population on Brooklyn on July 4, 1918 when his MCU birth occurred was approximately 1,900,000 people.
Spiderman, (Peter Parker) is from Queens. The population on August 10, 2001 when his MCU birth occurred was approximately 2,300,000 people.
1/7 of their sum is this number....
What is 600,000 ?
1,900,000 + 2,300,000 = 4,200,000
4,200,000 x (1/7) = 600,000
This is the expression for "10 less than the quotient of 3 times a number and 12"
What is (3x / 12) - 10 ?
The answer to "4 less than the quotient of 3 times a number and 7 = 20" is.....
What is 56?
"4 less than the quotient of 3 times a number and 7 = 20" is written as (3x / 7) - 4 = 20
If we didn't take 4 away from 3x/7 to get 20, we would see that 3x/7 alone is equal to 24
(3x / 7) = 24
So whatever 3x is, if we broke that into 7 groups, there would be 24 in each group.
The number that 3x is equivalent to (if we added all 7 groups of 24 together) would be 168
So 168 is the same as 3x
3x = 168
x = 56
(3(56)/ 7) - 4 = 20
(168/7) - 4 = 20
24 - 4 = 20
20 = 20
Paco's error is when he divided by -3 to both sides.
