Answer:
ok the answer is 20
Step-by-step explanation:
It helps me to convert the fractions into decimals, so 11/15=.73 and -5 1/2= -5.5.
Next, just add -5.5 to .73, you should get -4.77, then convert that back to a fraction and get -4 23/30 :)

If the question is 418/19, then the answer is 22
Answer:
<em>Similarity doesn't changes angle measures</em>
- ∠U = 56°, ∠U' = 3x - 16
- ∠U = ∠U'
a) 3x - 16 = 56 ⇒ 3x = 72 ⇒ x = 24°
b) ∠T = x + 46 = 24 + 46 = 70°
c) <u>Scale factor:</u>
- k = S'T'/ST = 19/57 = 1/3
<u>Find y using known sides and scale factor:</u>
- U'V'/UV = 1/3
- (y + 4)/63 = 1/3
- y + 4 = 21
- y = 21 - 4
- y = 17
The answer is 1/10 you move the decimal over 2 twice to the left
