The (greatest, least) of the common factors of two or more numbers is the (greatest, least) common factor of the numbers.

Answers


You could go both ways with this question, and they're both true:

-- circle "greatest" in both places;

-- circle "least" in both places;  also true, but whatever the numbers are,
their least common factor is always ' 1 ', so it's not very useful.


On Monday John had $500 . Over the weekend he went out to eat for $ 112and used his debit card for movie tickets that cost $28 . How much money did John have on Tuesday?

Answers

This question is a little ambiguously worded, however I assume the answer would simply be:
$500 - $112 - $28 = the amount he has left.

Answer: 7.5


Step-by-step explanation:

• Cross multiply : start by multiplying 15 times 3

• You get 45, then you divide 45 by 6

• Therefore, this gives you 7.5

• Check your answer by plugging in 7.5 to x

• Both fractions should equal 0.4, meaning they are equal to each other

x² - d = (x + 9) (x + c)
c and d are integers.

Integers are whole numbers found in the number line. These can be positive integers or negative integers.

x² - d ⇒ this means that there is no middle term. The sum of the middle term is 0.

(x + 9)(x - 9) = x(x - 9) + 9(x - 9) = x² - 9x + 9x - 81 = x² - 81

c = -9
d = 81

x² + Mx + 18 = (x + g)(x + h)

if M = -11
x² - 11m + 18 ⇒ (x-9)(x-2) ⇒ x(x-2) -9(x-2) 
x² - 2x - 9x + 18 ⇒ x² - 11x + 18

if M = 7
x² + 7m + 18 ⇒ (x + 9)(x-2) ⇒ x(x-2) + 9(x-2) 
x² - 2x + 9x - 18 ⇒ x² + 7x - 18

Only Pat is correct.
M = -11
g = 9
h = 2

Anna-Maria has added 4 quarts of an alcohol in water solution to 1 quart of water and her ending product is a 36% alcohol in water solution. What was the concentration of the 4 quarts of alcohol solution that was added?

Answers

The concentration of solution would be the amount of the molecule divided by the volume. In this case, the solution concentration is 36% and the volume is 4 quarts + 1 quarts= 5 quarts. You are asked the concentration before 1 quarts added. The alcohol content should be same for both solutions. The answer should be:

concentration = alcohol content/ volume
alcohol content =concentration * volume
alcohol content1 =alcohol content2
36% * 5 quarts = concentration2 * 4quarts
concentration2= 36% * 5 quarts / 4 quarts= 45%
