Answer: Rahul walks 2.7 km more than Vansh.
Step-by-step explanation:
The options include:
a. Vansh walks 7.2 km more than Rahul.
b. Vansh walks 2 km more than Rahul.
c. Rahul and Vansh both cover the same distance.
d. Rahul walks 2.7 km more than Vansh.
Distance covered by Rahul weekly = 9km
Distance covered by Vansh weekly = 900m × 7 = 6300m = 6300/1000 = 6.3km
From the above, we can see that Rahul walk (9km - 6.3km) = 2.7km more than Vansh.
Note: 1000 meters = 1 kilometers

Answer:
x=90/16,y=-150/16
Step-by-step explanation:
Simultaneous equation and we are to use elimination method
9x+y=30...(1)
6x-y=15..(2)
Add (1) and (2)
16x=15
Divide both sides by 16
x=15/16
Then substitute the value of x into (2)
6(15/16)-y=15
90/16-y=15
Substrate 15 from both sides
90/16-y-15=0
Add y to both sides
90/16-15=y
Lcm for only the left side which is 16
90-240/16=y
-150/16=y
Therefore x is 90/16 and y is -150/16
Answer:
x = -1/2
Step-by-step explanation:
2x + 4y = 13
3x + y = 2 (you can multiply this equation by -4 in order to eliminate the y-term)
-4(3x + y = 2) = -12x - 4y = -8
+ <u>2x + 4y = 13</u>
-10x = 5
x = -5/10 or -1/2
x(-1/2) + 4y = 13
-1 + 4y = 13
4y = 14
y = 14/4 or 7/2 or 3 1/2
It will be 2/5 ft long and 7/25 ft wide. 200•1/500=2/5
140•1/500=7/25
