Step-by-step explanation: The opposite of Multipication is division so divide 84 by 12

Answer:

k=7

Step-by-step explanation:

Call me weird but I love these types of questions.

Ok to solve this here's what you need to do.

Your solving for k right?

So make an equation.

Product is the result of multiplication so 12 and k would be 12k.

It needs to equal 84 so 12k=84

Now you need to get rid of 12.

You need to use the opposite operation as the number your trying to get rid of. In this case it would be division.

[you do not divide the x because you need it alone on one side]

So 12k divided by 12 = 84 divided by 12

12k/12 is k because a number divided by itself is 1.

84/12 is 7.

that leaves us with k=7

Thats it!

The perimeter of the triangle ABC will be 54 units.

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

In the diagram, AC is parallel to RP.

Then the triangle ABC and RBP will be similar.

Then the ratio of the corresponding sides will be constant.

BP / 10 = 7 / 14

      BP = 5

Then the perimeter of the triangle ABC will be

Perimeter = 7 + 14 + 18 + 10 + 5

Perimeter = 54 units

Step-by-step explanation:

PQR = PRQ = 2x ° ( base angle of an isosceles are equal ) .

therefore

PQR + PRQ + QPR = 180° ( sum of angles in a triangle )

2x + 2x + 40 = 180

4x + 40 = 180

subtract 40 from both sides

4x = 140

divide through by 4

x = 35°

1).Sugar used in 7 days = 61.25 pounds

2). Total cost of 9 cupcakes = $38.25

Step-by-step explanation:

1). Alani uses 8.75 pounds of sugar each day.

  So, sugar used in 7 days = Amount of sugar used in one day × Number of    days

= 8.75 × 7

= 61.25 pounds

2). Since, each cupcake costs $4.25

   Number of cakes ordered = 9

  Total cost of 9 cupcakes = Cost of each cupcake × Number of cupcakes

                                             =  4.25 × 9

                                             = $38.25

Answer:

C. p

Step-by-step explanation:

Given the expression p - q = 0

We are to find the value of q

Substract p from both sides;

p - q - p = 0 - p

-q = - p

Multiply both sides by -1

-(-q) = -(-p)

q = p

Hence the correct solution is q = p

Explanation:

In a standard deck of cards, there are 52 cards. They are broken down into suits (4 of them: Spades, Hearts, Diamonds, Clubs) of 13 cards each. Each suit has 13 ordinal cards (A, 2 through 10, Jack, Queen, King).

Here we're asked to draw a card at random and find the probability of drawing either a diamond or a 9.

With probability, we look at the fraction of ways we can achieve some condition (the numerator) over the number of ways we can do something (the denominator).

Our denominator here is 52 - the number of cards from which we can pull 1.

Our numerator is both all the diamonds, 13 cards, and all the nines, 4 cards, but we need to subtract 1 to account for the double counting of the 9 of diamonds.

In all we get:

13+4 - 1/52 =

≈  16/52

=4/13

Answer: 0.3077

Probabilities are used to determine how likely an event is, to happen. The probability of drawing a 9 or diamond is: 4/13

In a standard deck of cards, we have:

[tex]n = 52[/tex] --- There are 52 cards in total

[tex]n(9) = 4[/tex] ---- Cards with number 9 are 4

[tex]n(Diamond) =13[/tex] ---- there are 13 diamonds

[tex]n(9\ n\ Diamond) = 1[/tex] ---- Diamond cards with number 9

The probability of drawing a 9 or diamond is:

[tex]P(9\ or\ Diamond) = P(9) + P(Diamond) - P(9\ n\ Diamond)[/tex]

So, we have:

[tex]P(9\ or\ Diamond) = \frac{n(9)}{n} + \frac{P(Diamond)}{n} - \frac{n(9\ n\ Diamond)}{n}[/tex]

This gives:

[tex]P(9\ or\ Diamond) = \frac{4}{52} + \frac{13}{52} - \frac{1}{52}[/tex]

Take LCM

[tex]P(9\ or\ Diamond) = \frac{4+13-1}{52}[/tex]

[tex]P(9\ or\ Diamond) = \frac{16}{52}[/tex]

Simplify

[tex]P(9\ or\ Diamond) = \frac{4}{13}[/tex]

Hence, the probability of drawing a 9 or diamond is: 4/13

Answer:

C

Step-by-step explanation:

We have the system of equations:

[tex]\displaystyle -2x+5y=19 \\\\ y=-\frac{5}{6}x-\frac{1}{6}[/tex]

And we want to use the graph to approximate the solution to the system.

Remember that, graphically, the solution to a system of equations is where the two graphs intersect.

We can see that the point at which the two lines intersect is in QII.

Hence, x is negative and y is positive.

The only choices that satisfies these conditions are B or C.

However, for B, -5/2 is -2.5. As we can see from the graph, the x-coordinate of the point of intersection is less than -3.

Hence, the only choice left is C. -13/4 also is -3.25, fulfilling our condition.

So, our final answer is C.
