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.
Answer: -4
Step-by-step explanation: Let me know if you need an explanation.
Answer:
Missing Truck Value=6
Missing Car Value=45
Step-by-step explanation:
Since the ratio of trucks to cars is 2:3, you do 3 times 3 equals 9. Since all 3 ratios needed to be equal, we have to do 2 times 3 which is 6. That is how you get the truck value. We do the same to get the car value. 6 times 5 is equal to 30, so we do 9 times 5 too. That gives you 45.
Answer:
x = 71°
Step-by-step explanation:
By applying triangle sum theorem in ΔBHD,
m∠DBH + m∠BHD + m∠HDB = 180°
40° + m∠BHD + 31° = 180°
m∠BHD = 180° - 71° = 109°
m∠BHD + m∠DHE = 180° [Linear pair of angles]
109° + x° = 180°
x = 180° - 109°
x = 71°
