Let us say that this number is n
Then we could say:
<em><u>n - 9</u></em>
5/2 • 4/1 (flip the second fraction to multiply)
20/2
10
A
Answer:
2(x+2)
Step-by-step explanation:
Factor out the 2.
we have: ∠P + ∠Q + ∠R = 180°
<=> (4x – 14)º + (5x + 6)° + (x - 2)° = 180°
<=> 4x – 14 + 5x + 6 + x - 2 = 180°
<=> 10x - 10 = 180°
<=> 10x = 190
<=> x = 19°
So: ∠R = (x - 2)° = (19 - 2)° = 17°
ok done. Thank to me :>
