Answer:
984
Step-by-step explanation:
DVDs comprises 31.3% of total. And we also know that there are 308 DVD. Thus, we can say:
308 is 31.3% of total
We can let total be x, thus we can write an equation as:
308 = 0.313x
Solving for x:
We can round and say there are 984 total movies
Answer:
x = 10, y =
Step-by-step explanation:
The opposite sides of a parallelogram are congruent.
For LMNO to be a parallelogram then
ON = LM and OL = NM, that is
ON = LM
7x - 6 = 6x + 4 ( subtract 6x from both sides )
x - 6 = 4 ( add 6 to both sides )
x = 10 , then
NM = x - 9 = 10 - 9 = 1 and
OL = NM , that is
3y - 3 = 1 ( add 3 to both sides )
3y = 4 ( divide both sides by 3 )
y =
