Answer:
the scores on her last test is x (x > 0)
because on her last tests she scored 4 points lower than she did on her fifth test
=> the scores in the 5th test is x + 4
because Angela’s average for six math tests is 87, we have:
=> on her last test, she had 85
=> on her 5th test, she had 85 + 4 = 89
These types of problems are all about recognizing key words. The word IS means EQUALS.
Eya is 3 times Bill's age but 5 less than that.
E = 3B - 5
If Eya is 28 now,
28 = 3B - 5
Add 5,
33 = 3B
Divide by 3 as a final step to solve for Bill's age.

If Δ ABC is similar to ΔLMN, then angle A corresponds with angle L, B corresponds to angle M and C corresponds to N.
The sum of angles in a triangle add up to 180.
Therefore, angle A = 180- (95 +35)
= 50
but, corresponding angles are equal;
Hence angle L = 50°
