5 0

Answer: The fifth piece of paper could have any number 9 and less or 14 and greater.

Step-by-step explanation:  The list of choices is not given in the question, but it makes sense that the new number would not be a duplicate of any of the numbers 10, 11, 12, 13. Otherwise that would change the probability to 5/5.

So any other number could be a possibility.

Roland purchased a new pair of shoes online that normally sell for $125.00 but were marked down to $93.75. What is the discount
Ad libitum [116K]

Answer:

25%

Step-by-step explanation:

125.00x = 93.75

x = 93.75 / 125 = 0.75

meaning that 93.75 is 75% of 125

and, therefore, the item was discounted 100 - 75 % = 25%

12. Find the slope and y-intercept of the line. y= 1/5x-8
eduard

Hello and Good Morning/Afternoon:

<u>Let's take this problem step-by-step</u>:

<u>What does the problem want us to find:</u>

  • slope
  • y-intercept

<u>Let's gather the information</u>:

  ⇒ the information given: y = 1/5 x - 8

        ⇒ the line is in <u>slope-intercept form</u>

            ⇒ means:

                     ⇒ coefficient in front of 'x' is the slope

                     ⇒ constant is the y-intercept

  • slope is 1/5
  • y-intecept is -8

<u>Answer:</u>

  • <u>Slope is 1/5</u>
  • <u>y-intercept is -8</u>

<u></u>

Hope that helps!

Ok so we have the first portion. We need to do cross multiplication first. So that would be 20(2x - 9) and 10(9)

So
20(2x - 9)=90
40x - 180=90
Then add 180 to itself then to 90
40x=270
X=6.75

Now let’s set the next one up knowing what we know from the previous one.

18(3x + 4)= 12(15)
54x + 72=180
Subtract 72 from it’s self and 180
54x=108
X=2

HELP ASAP!! Identify the least common multiple of x^2 + 7x + 6 and x^2 − 3x − 4.
vesna_86 [32]

(x+1)(x+6)(x-4)

The least common multiple (LCM) of two or more non-zero whole numbers is the smallest whole number that is divisible by each of those numbers. In other words, the LCM is the smallest number that all of the numbers divide into evenly.

Hope This Helps & Good Luck
