Laura bought a notebook and pencil for $4.50 the notebook cost twice the amount of the pencil
write a system of equation to find the cost of the notebook and pencil

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

b 1: 45 am

step-by-step explanation:

its that because if it was in the pm it would be 1345

assuming this is from a math graphing problem.

7 would be on the x-axis which is the horizontal line on the graph

84 would be on the y-axis which is the vertical line on the graph
