Answer:
∠A=30°
Step-by-step explanation:
let's call the angle at the bottom B and the one next to the 130 C
∠A=3x-6
∠C=180-130= 50°
vertical angles are equal∠B =8x+4
∠A+∠C+∠B=180°
find x:
3x-6+50+8x+4= 180°
11x+48=180°
11x= 132
x=12
find ∠A
∠A=3x-6= 3(12)-6 =30°
3 divided by (4 + n). Hope it helps! :)
Answer:
200
Step-by-step explanation:
Answer:
2 hours and 24 minutes
Step-by-step explanation:
1/6 + 1/4 = 2/12 + 3/12 = 5/12
5/12 = 1/x
5/12x = 1
5x = 12
x = 2.4
2 hours, 24 minutes
Let x be the number of gb used.
Question (1):
Runfast = 10 + 4x
<span>BA&D= 6 + 6x
Question (2):
</span> 10 + 4x = 6 + 6x
2x = 4
x = 2
Both companies will cost the same if you use 2 Gb of data.
BA&D will be cheaper if you use less than 2 Gb of data.
Runfast will be cheaper if you use more than 2 Gb of data.
