Answer: N=3

Step-by-step explanation:

Let's represent notebooks with "N" and pencils with "P".

Then,

N + P = 4.50

Since N =2P, we can substitute that directly into the equation:

(2P) + P = 4.50

3P = 4.50 (divide both sides by 3)

P = 1.50

Now that we have P, we can in turn substitute that into the equation.

N + (1.50) = 4.50

N = 3.00

Need help with the problem in the photo.
mr_godi [17]

Answer:

  B.  3x -2y = 10

Step-by-step explanation:

The given line rises three units for each two units of run to the right. Hence its slope is 3/2. A parallel line will also have a slope of 3/2.

Of the equations we can see, selection B has a slope of 3/2. It can be rewritten in slope-intercept form as ...

  3x -10 = 2y . . . . . add 2y-10 to isolate the y-term; next divide by 2.

  y = 3/2x -5 . . . . . the coefficient of x is the slope

This id hard please help me do this

In this problem, we're going to use the 'PEMDAS' method.

First, we're doing the problem in the parenthesis.
44 - 4 = 40

Next in PEMDAS, we need to do the exponent.
6² = 6 x 6 = 36

Then we would do multiplication, but there is nothing to multiply so we move onto division.
40 / 2 = 20

Now we would add, but there is nothing to add so we move onto subtraction.
20 - 36 = -16

Our final answer would be -16.

Hope this helps!~

If you roll one die two times, what is the probability of getting a 2 on the first roll and a 2 on the second roll? Show work or
koban [17]

Answer:    \dfrac{1}{36}

Step-by-step explanation:

We know that when two events A and B are independent , then the probability of getting A and B will be :-

P(A\cap B)=P(A)\times P(B)

In a fair dice,total outcomes =6

Number of 2's =1

Then, the probability of getting a 2 =\dfrac{1}{6}

If you roll one die two times, then the probability of getting a 2 on the first roll and a 2 on the second roll will be:-

\dfrac{1}{6}\times\dfrac{1}{6}=\dfrac{1}{36}

Hence, the probability of getting a 2 on the first roll and a 2 on the second roll=\dfrac{1}{36}
