x+2
quotient:
Answers
Answer:
The correct option is C.
C) -x + 2
Step-by-step explanation:
In mathematics, the term which is being divided is called a dividend. The term by which the dividend is getting divided is called a divisor. The quotient is the term we get after dividing the dividend by a divisor.
Here in this case, the dividend is written.
-x² x x
which in the equation form is written as
-x² + x + x
add the x terms to simplify
-x² + 2x
The divisor is given as x, divide the equation by x:
(-x² + 2x)/x
(-x²/x) + (2x/x)
-x+2
Which is the quotient.

Suppose that the mean number of chocolate chips in 30 cookies is 19 chocolate chips. Explain what this means.
Answers
Answer: It means that there are 570 chocolate chips in all the 30 cookies
Step-by-step explanation:
The mean also referred to as the average of a data set is calculated by adding all numbers in a data set and dividing by number of values in the set.
Since the mean number of chocolate chips in 30 cookies is 19 chocolate chips, this means that there are:
= (30 × 19) = 570 chocolate chips in the cookies.

Mike can plow a field in 12 hours and his brother Phil can plow it in 15 hours. How long will it take them to plow it if they use two plows and work together?
Answers
Answer:
6.66 hours, that is, 6 hours and 40 minutes.
Step-by-step explanation:
If Mike can plow a field in 12 hours, we plows 1/12 of the field each hour.
If Phil can plow a field in 15 hours, we plows 1/15 of the field each hour.
So if they are working together, they can plow (1/12) + (1/15) of the field each hour, that is:
(1/12) + (1/15) = (5 + 4) / 60 = 9 / 60 = 3 / 20 = 1 / 6.66
So if they work together, they can plow the field in 6.66 hours, that is, 6 hours and 40 minutes.

Answers
Answer:
15/20 and 18/20
Step-by-step explanation:
Least common denomintor of 3/4 and 9/10 = least common multiple of 4 and 10
multiples of 4: 4, 8, 12, 16, 20
multiples of 10: 10, 20
Least common denominator = 20
Rewrite fractions: 15/20 and 18/20
3/4 and 9/10 using the least common denominator is 15/20 and 18/20.
What is LCM?LCM of two or more than two given numbers is the smallest common multiple that is divisible by two or more than two given numbers.
Given, are two fractions 3/4 and 9/10 we know the LCM of 4 and 10 is 20.
∴ (3×5)/(4×5) and (9×2)/(10×2). (we have to multiply same constant to the
fraction to retain it's original value).
So, 3/4 and 9/10 using the least common denominator is 15/20 and 18/20.

Answer only. What is the greatest possible sum of the digits of a six-digit number that is a multiple of 2, 3, 4, 5, 6, 7, 8, 9, 10 and 11?
Answers
Answer: 36
The LCM of 2, 3, 4, 5, 6, 7, 8, 9, 10 and 11 is 2 × 3 × 2 × 5 × 7 × 2 × 3 × 11 = 27720.
A multiple of 27720 will end in 0, and the sum of its digits will be a multiple of 9.
The largest 6-digit number which is multiple of 9 with last digit of 0 is 999990, and the sum of its digits is 45. 45 is not a multiple of 27720, and there is no other way to get a digit sum of 45.
We now look at the next biggest multiple of 9, 9 × 4
= 36.
The largest 6-digit multiple of 27720 is 27720 × 36 = 997920, and the sum of its digits is 36.

Answers
Answer:
b
Step-by-step explanation:
The correct answer for the given problem above would be option B.
⇒ Fran must work 17 hours per week to meet her goal.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Now, According to the given details,
Fran works 15 hours per week for $225 which makes it $15 per hour.
Hence, If she adds another 2 hours per week to make it 17 hours,
Then, she will earn $255 dollars per week.
Now, since she is saving $40 dollars plus the two hours which is $30, a total of $70 per week of savings, multiplied by 20 weeks, then, she will be able to get $1,400.
Hence, The correct answer for the given problem above would be option B.
⇒ Fran must work 17 hours per week to meet her goal.
