Answer:
Step-by-step explanation:
step 1
Find the measure of angle EFD
In this problem I will assume that ABCD is a parallelogram
In a parallelogram opposite angles are congruent and consecutive angles are supplementary
so
--- > given problem
Remember that the sum of the interior angles in any triangle must be equal to 180 degrees
so
In the triangle EFD
substitute the given values
step 2
Find the measure of angle EFB
we know that
---> by supplementary angles
we have
substitute
step 3
Find the value of x
Remember that the sum of the interior angles in any triangle must be equal to 180 degrees
so
In the triangle EBF
we have
substitute
solve for x

d $=d*100 cent
Let the unit cost of soda be p cents. So, unit cost of hot dog=2p cents
Total cost=cost of hot dog+cost of soda
or, 100d=h*2p+s*p=p(2h+s)
Or, p=100d(s+2h)p=100d(s+2h)

When interpreting graphs of real world situations, the slope of each part tell you the average rate of change (increase or decrease) of the dependent variable with respect to the independent variable. This is, how much the dependent variable increased (or decrease) per each unit the independent varaible increased, in average.
slope = change in independent variable / change in dependent variable
slope = Δy / Δx
