The cost of 3 notebooks and 2 pens is $10.45. the cost of 4 notebooks and 6 pens is $17.60.
part a - what is the cost of each item?
part b - miles needs to purchase some new school supplies. for each notebook he buys he will buy 3 pens. how many notebooks can he purchase if he has $22.

Notebooks cost $2.75 and pens cost $1.10.

He can also buy 3 notebooks.

Step-by-step explanation:

In order to find this, we need to create two equations given each of the situations.

3n + 2p = 10.45

4n + 6p = 17.60

Now to solve for n, multiply the top equation by -3 and add together.

-9n - 6p = -31.35

4n + 6p = 17.60

-5n = -13.75

n = 2.75

Now that we have the value of notebooks, we can find the amount for pens using either equation.

3n + 2p = 10.45

3(2.75) + 2p = 10.45

8.25 + 2p = 10.45

2p = 2.20

p = 1.10

Finally, to find the number of notebooks that he can purchase, find the cost of a notebook with 3 pens.

n + 3p

2.75 + 3(1.10)

2.75 + 3.30

6.05

Now divide 22 by that number

22/6.05 = 3.63

Since we can't have fractional notebooks, we round down to 3.

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.
