y = -x + 1/3
+ x + x
--------------------------
x + y = 1/3
Answer: If you're looking for the sum of the equation, it's 9.57.
If you're looking for a better way to add it. It's this. (1.7 + 5.3) + 2.57.
Step-by-step explanation: The reason for my answer is quite simple. Since 1.7 and 5.3 add up to 7, all you need to do is add 7 and 2.57. That way, it's much easier to get the answer 9.57
Hope this helped :)
Answer:
The distance travelled is 7.98×10³ miles.
Step-by-step explanation:
Given that the formula to find distance is Distance = Speed×Time. Then you have substitute the values into the formula :
Let speed = 5.7×10²,
Let time = 1.4×10¹,
1- y= x/2 + 2
2- y= 3x +1
3- y= x/2 - 2
4- y= 3x - 1
She walked 7 miles. If it takes her one hour to walk four miles, then it will take 45 minutes to walk 3 miles.
