Answer:
55+20
Step-by-step explanation:
Answer:
Second option: 
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:

Where "m" is the slope and "b" is the y-intercept.
We know that a line goes through the points
and 
Since the line intersects the y-axis when
, then the y-intercept of this line is:

Substitute the y-intercept and coordinates of the point
into the equation
and solve for "m":

By definition, the slopes of parallel lines are equal, then the slope of the other line is:

Knowing that it passes through the point
, we can substitute values into the equation
and solve for "b":

Therefoe, the equation of this line is:

a common what? denominator?
Let h be hot dogs and s be sodas
h+s=221
h=s-59
s=s
s+s-59=221
2s-59=-221
2s=280
s=140
h=140-59=81
140+81=221
Answer: there were 81 hotdogs and 140 sodas sold
Answer:
31.5 inches
Step-by-step explanation:
A = 1/2 h l
A= 1/2 (7) (9)
A = 1/2 (63)
A = 31.5 inches
h=height
l=length of base
