Hi Ivan
-6n - 20 = 2n + 4(1 - 3n)
-6n - 20 = 2n + 4 - 12n
Combine like terms
-6n - 20 = 2n - 12n + 4
-6n - 20 = -10n + 4
-6n + 10n = 4 + 20
4n = 24
n = 24/4
n= 6
I hope that's help! If you have any further questions please let me know !
Answer:
Step-by-step explanation:
<u>Use the law of sines:</u>
- AC / sin B = AB / sin C
- 100 / sin B = 250 / sin 95°
- sin ∠B = 100 sin 95° / 250
- sin ∠B = 0.39847787923
- m∠B = arcsin 0.39847787923
- m∠B = 23.5° (rounded up)

Step 1: Subtract 8 from both sides.
5/4y+ 8− 8= 17.5− 8
5/4y = 9.5
Step 2: Multiply both sides by 4/5.
(4/5) * (5/4y) = (4/5) * (9.5)
y = 38/5
