Answer:
2000 meters
Step-by-step explanation:
From the above question
Total time = 15 minutes
Converting minutes to seconds
1 minute = 60 sec
15 minutes = x
Cross Multiply
x = 60 × 15 = 900 seconds
Hence, 900 seconds = Total time
Total time = Time to the marker + Time from the marker
From the question, we are given the Speed to the marker = 5 m/s
Speed from the marker = 4 m/s
Time = Distance/speed
Let the distance be represented by x
Hence:
x/4 + x/5 =900
Multiply all through equation by Lowest Common Denominator = 20
5x + 4x= 900×20
9x = 900 ×20
Divide both sides by 9
9x/9 = 900 × 20/9
x = 2000 meters
Therefore, the total distance to the marker = 2000 meters
Well
first one doesn't need that property
2nd one needs subtraction property of equality
third one can use it
fourth one needs addition property of equality
3rd one is answer
b/-2=18 is answer

Answer:
Step-by-step explanation:
1) 15% of 75 = (15/100) * 75 = 0.15*75 = 11.25
2) 7% of 980 = 0.07 * 980 = 68.6
3) 45%of 62 = 0.45 * 62 = 27.9
4) 22% of 198 = 0.22 * 198 = 43.56
