678 is what you have left but if you would put it as a fraction of what you have left now it would be 678/1012... which then take and put it as a decimal which is a form of a mixed number = .6699
Answer:
X= -7 ± √17 / 16
x= - 0.7798...
Step-by-step explanation:
Hi! For this problem, you must replace the letter “X” with the number 2. Your equation will then be (2*1)- (2-1)+ (2*0). This will then simplify to: 2 - 1 + 0. Therefore, your final answer will be:
1
<span>Uphill distance = 1 4/5 = 9/5 = 18/10 km
Downhill Distance = 2 7/10 = 27/10 km
Total Uphill and Downhill = 18/10 + 27/10 = 45/10 = 4.5 km
Hence total level ground = Total race km - (Uphill + Downhill)
=10 - 4.5 = 5.5 km
Hence the answer is 5.5 km.</span>
