The degree would be 120 degrees
Answer: 
Step-by-step explanation:
Given
The area of the square is 
Suppose a is the side length of the square
The area of the square is given by

So, we can write

length of each side is 
Answer:
3/4(-10+2+2/5)
answer -5.7
Step-by-step explanation:
-
2 boxes for $6.00 5 Bars each is 10 bars for $6.00 or $3.00 for 5 bars
so $6.00 divided by 10 =.60 or 60 cents per bar
12 bars for $7.44 is $7.44 divided by 12 =.62 or 62 cents per bar
so the difference between 60 cents and 62 cents is
2 cent Difference
Step-by-step explanation:
x = number of multiple choice questions
y = number of short response questions
x + y = 15
5x + 10y = 100
=>
x + 2y = 20
let's subtract the first from the second equation :
x + 2y = 20
- x + y = 15
--------------------
0 y = 5
x + y = 15
x + 5 = 15
x = 10
to graph you need to consider both equations as linear functions. and you need to transform them into e.g. a slope intercept form : y = ax + b
a is the slope, b is the y- intercept.
x + y = 15
transforms to
y = -x + 15
this line goes e.g. through the points (0, 15) and (1, 14).
and
x + 2y = 20
transforms to
2y = -x + 20
y = -x/2 + 10
this line goes e.g through (0, 10) and (2, 9).
the crossing point of both lines is the solution and should therefore be the point (10, 5) as calculated above.
