2
Step-by-step explanation:
this one is correct
1/5+1/5=2/5
Answer: Option C
, 
Step-by-step explanation:
If the lines m and n are parallel then the large triangle and the small triangle are similar triangles, because they have equal angles.
By definition for similar triangles it is satisfied that if they have sides of length a, b, c and a', b', c' then:

In this case

So:

Now solve the equation for the variable y



We know that
and 
Then


Finally the answer is:
, 
Answer:
$933.3
Step-by-step explanation:
Given data
Principal= $900
Rate= 7.55%
Time= 180 days>>> 6months>>> 0.5 years
Say the account is on a compound interest plan
A= P(1+r)^t
substitute
A= 900(1+0.0755)^0.5
A= 900(1.0755)^0.5
A= 900*1.037
A= $933.3
Hence the teacher will withdraw $933.3 on a compound interest investment after 6 months
B and C are both equations because they both have equal signs.
10099 is this right i think it would be
