Answer:
a is parallel to d
a and d are parallel, and are perpendicular to c and d (those are parallel to each other)
RESULT
They are parallel
Step-by-step explanation:
2<3+x
subtract 3 on both sides
2-3<3-3+x
simplify
-1<x
this can also be rewritten as
x>-1
Answer:
range of scores on final exam student get B is 90 to 100
Step-by-step explanation:
given data
Psychology 101 score = 66
average of his midterm = between 78 and 90
maximum = 100 points
to find out
range of scores on final exam student get B
solution
we consider here lowest marks need in final = x
so average at two marks should be
equation is
average marks = 0.5 × ( mid term marks + final marks ) .................1
put here value
78 = 0.5 × ( 66 + x )
x = 90
and
90 = 0.5 × ( 66 + x )
x = 114
so range 90 to 114
but maximum marks is 100 so
range of scores on final exam student get B is 90 to 100

Answer:
The value of x is 
Step by step explanation:
In the question we are given a product that contains two unknown variables, i.e. 
and 
. To solve for we shall first compute the product between the two brackets. I will show each step in full detail, in order to understand the product computation of such cases (i.e. distributive property).
Up to this point we have computed the product and now we have all our terms. Since we want to find the value of we will gather together all terms that contain (even if they also contain ) and then do some manipulations and simplifications to obtain our result, as follow:
Now we see that on both sides of the equality we have a common term of 
, which we can cancel out from both sides, which leaves us with:
Thus the value of is .
