Let s = #small notebooks

Let L = #large notebooks

 

We Can set up two equations from the info given.

 

s + L = 6           bought 6 notebooks total

8s + 10L = 56    spent $56

 

Solve equation 1 for one variable.

L = 6-s

 

Plug 6-s in equation 2 in place of L

and solve for s

 

8s + 10(6-s) = 56

8s + 60 - 10s = 56

-2s + 60 = 56

-2s = -4

s = (-4)/(-2)

s = 2

 We know s+L = 6 and s=2

2+L = 6

L = 4

 4 large notebooks and 2 small notebooks

were purchased

PLEASE ALSO EXPLAIN HOW TO SOLVE THIS. 20 POINTS

B.) Hibiscus Street 

The key thing to remember is the slope of the lines. The equation for a line in slope intercept form is
y = ax + b
where
a = slope
b = y intercept

So the equation for Oak Street is y = 2/3x - 7. So it's slope is 2/3. And any street that has the same slope will be given a tree name. And any street that's perpendicular will be given a flower name. You can determine is a line is perpendicular if it has a slope that's the negative reciprocal. So a street that's perpendicular to Oak street will have a slope of -3/2.

Now you've just been given the equation to a new street that's y = -3/2x - 2. Since the slope is -3/2 and Oak street has a slope of 2/3, the new street is perpendicular to Oak street. And given the naming scheme, that means that the new street will have the name of a flower. So let's look at the available street names and pick a flower.
<span>
A.) Weeping Willow Street
* Nope a Weeping Willow is a tree. So this name won't work.
 
B.) Hibiscus Street 
* Yes. A Hibiscus is a flower, so this name is suitable.

C.) Oak Street 
* Nope. Not only is this a tree instead of a flower, but there's already an Oak street. So bad choice.

D.) Panther Street
* Nope, this is an animal, not a flower. Bad choice.
