Josh and Anthony have a lemonade stand.They charge $1 for 2 cups of lemonade.They sell 14 cups each afternoon.Is it reasonable to say Josh and Anthony earned more than $50 after 3 afternoons?

Answers

No it is not, whatsoever.

$1 for 2 cups. 14 cups in an afternoon means they got $7. If they did this for three days (7 x 3) they'd have 21 dollars. it is not reasonable because 21 is nowhere near 50.

Write the equation of a line whose slope is 2/3 and crosses the y axis at (0, -5)

Answers

The equation of line with slope 2/3 and crosses the y axis at (0, -5) is:

y=(2)/(3)x-5

Step-by-step explanation:

We will use the slope intercept form of the equation to make an equation of the given line

The slope-intercept form is:

y=mx+b

Here m is the slope and b is the y-intercept

Given

m = 2/3

Putting the value of slope

y=(2)/(3)x+b

The y intercept is -5 so we will put in the equation

y=(2)/(3)x-5

The equation of line with slope 2/3 and crosses the y axis at (0, -5) is:

y=(2)/(3)x-5

What is the answer to -12(k+4)=60

Answers

-12(k+4)=60\n\nk+4 = -5\n\n\boxed {k =-9}
-12 (K+4) = 60
Using Distributive Property:
-12K -48  =60
then 
-12 K = 60 + 48
-12K = 108
Divide both sides by  -12 

Then
K = -9
