Answer:
each person pays $190
all together the rent is $950
Step-by-step explanation:
240 - 50 = 190
190 x 5 = 950
The equation that best models this situation would be: y=40+30x
Answer:
do the following
Step-by-step explanation:
subtract the 2nd equation from the 1st....
x-2y = 14
-(x+ 3y = 9)
______________
-5y=5
y= -1
since you know that y is = to - 1 pick the 3rd answer
Answer:
Area of trapezoid = 67.6 square units
Step-by-step explanation:
Area of a trapezoid is given by the expression,
Area of the trapezoid = 
Here,
and
are the parallel sides of the given trapezoid.
And '
' = Height between the parallel sides
From the given triangle ABE,
m(∠ABE) = m(∠ABC) - m(∠EBC)
m(∠ABE) = 120° - 90°
= 30°
By applying cosine rule in the given triangle,
cos(30°) = 


BE =
units
By applying sine rule in ΔABE,
sin(30°) = 


AE = 3 units
Length of 
Length of
[AE = FD, since given trapezoid ABCD is an isosceles trapezoid]


Height between the parallel sides 
Area of the trapezoid = 
= 
= 
= 67.6 square units
