11.5, when rounded to the nearest tenth the answer was 11.468 but we need to round and 6 is 5 and higher so the 4 would become a 5. The answer is 11.5
Answer:
y=3x-5y
Step-by-step explanation:
|PR| = |PQ| + |QR|; |PQ| = |QR| conclusion |PR| = 2|PQ|
|PQ| = 3y; |PR| = 42; |QR|=?
subtitute
42 = 2(3y)
6y = 42 |divide both sides by 6
y = 7
|QR| = 3(7) = 21
Answer:
Step-by-step explanation:
6/y=9/5(due to similarity)
y=6*5/9=30/9=10/3=3.333..
