The quotient of 56 and n is multiplied by 3.

Nutka1998 [239]

Answer:

Equivalent expression using n to represent the unknown number is: $\mathbf{(\frac{56}{n})\times 3\\}$

Step-by-step explanation:

The quotient of 56 and n is multiplied by 3.

Create an equivalent expression using n to represent the unknown number.

We need to write equivalent expression of The quotient of 56 and n is multiplied by 3.

We will do this step by step

First we will find:

The quotient of 56 and n

It can be written in mathematical form is: $\frac{56}{n}\\$

Now, we will find

The quotient of 56 and n is multiplied by 3.

It can be written in mathematical form as: $(\frac{56}{n})\times 3\\$

So, equivalent expression using n to represent the unknown number is: $\mathbf{(\frac{56}{n})\times 3\\}$

A red die is tossed and then a green die is tossed. What is the probability that the red die shows a number larger than three or

lianna [129]

Answer:

Red: 67%

Green: 33%

Step-by-step explanation:

Since each die has 6 sides, there is a 1/6 chance for every number.

Probability for a number higher than 3 would be 4/6, which is about 67%.

Probability for below 3 would be 2/6, which is about 33%.

I am not 100% sure, but I hope this helps you.

Please help this is so confusing to me

Stels [109]

First multiply C by F by multiplying each row in C by each column in F:

12 * -2 + 0*0 + 1.5*2 12*0 + 0*8 + 1.5*1

1*-2 -6*0 +7.2 1*0-6*8 +7*1

to get a matrix of:

-21 1.5

12 -41

Now subtract that matrix from B:

2- -21 = 2+21 = 23

8 - 1.5 = 6.5

0.6 - 12 = -11.4

3 - -41 = 3+41 = 44

So you have:

23 6.5

-11.4 44

Which makes C the correct answer.
