Answer:
37.68 i think
Step-by-step explanation:
3x-2y=7
3x=7
x=7/3
-2y=7
y=-7/2
so...(7/3,-7/2)
If the shapes are similar, the correspondent sides are in proportion:

Let's plug the values and solve for x:

Multiply both sides by x to get

The only feasible solution, though, is
, because it wouldn't make sense to have negative lengths.
Answer: Last option
The number -8.4 is a solution to the inequality because -8.4 is located to the left of
on the number line.
Step-by-step explanation:
Note that: 
The inequality is:

The inequality is:
This means that the inequality includes all values of the number line that are less than -3.25 or that are to the left of -3.25
__-8.4_________-3.25_-3____0___0.9____________7.1__
Note that the number -8.4 is less than -3.25, because it is to its left on the number line.
Then the correct statement is:
The number -8.4 is a solution to the inequality because -8.4 is located to the left of
on the number line.
