To answer this item, we let x be the time in which Tyler and Sophia will be able to cover the same distance along the circular track. Since Sophia runs faster, she will be able to finish the track and y meters more while Tyler will be able to finish y meters only.
5(x) = 400 + y
4(x) = y
The values of x and y are 400 and 1600. Thus, it will take 400 seconds for then to meet again.
1 : do 10 - 7 = 3
2: -2.5 • 3 = -7.5
3: -7.5 + -5 = -12.5
The answer is B
Okay well since it is posivtive moe the decimal to the right the amount of times the power is. 9.203*10^6 ANSWER: 9,203,000
First I would distribute the left part like so:
12x - 18 - (5x + 7)
Then I would distribute the right side like so: (I'm just distributing a negative sign)
12x - 18 - 5x - 7
Then I combine like terms like so: (12x and -5x)
7x - 18 - 7
Then I would combine the other like terms like so: (-18 and -7)
7x - 25
I hope that helps! Feel free to let me know if you have any questions! :3
