the orginal price was 64 dollars
I believe it might be that x would be negative six. A triangle is supposed to sum to 180 degrees. An equation could be 180 = 52 + 78 + 56 + x.
Question: 2x - 4 + 5x
Simplified: 7x - 4
Answer:
direct relation between distance travelled by a train and its speed, when time is constant.
Step-by-step explanation:
We know that the speed of an object is the total distance covered divided by total time taken. Mathematically, it is given by :
Where
d is distance
t is time taken
It can be seen that relation between the distance and the speed is direction. Hence the correct option is (a) "direct".
