Answer:
The equation you are asking for is
40*(t+3) = 55*t,
where t is the time counted after the second car started.
The equation says that the distance covered by each car from the starting point to the catching point is the same for both cars.

Step-by-step explanation:</h3>
• When working with variables and numbers, you have to put the variables first (in alphabetical order) and then the numbers.
• To evaluate an algebraic expression, we find the value of the expression when the variable is replaced by a given number.
• To evaluate an expression, we substitute the given number for the variable in the expression and then simplify the expression using the order of operations.
• When we are not given a number for the variable in the expression, we have to group like-terms.
- <u>Example:</u> 5x + 6 + 3x - 2 - y
- 1st: group 5x and 3x (add the terms together) = 8x
- 2nd: group 6 and -2 (add the terms together) = 4
- 3rd: Since -y has no like-terms, we can't group it = -y
- Fourth, put the terms in order (variables = alphabetical order and then numbers) = 8x - y + 4
1. 4x + 12 - 3x + 8
- 4x - 3x = 1x = x
- 12 + 8 = 20
- x + 20
2. -8x + 1 + 2x - 1 + 6x
- -8x + 2x + 6x = -8x + 8x = 0
- 1 - 1 = 0
- 0
3. 4x - 3 - 2x - 5
- 4x - 2x = 2x
- -3 - 5 = -8
- 2x - 8
4. 100x + 5 - 5x + 5
- 100x - 5x = 95x
- 5 + 5 = 10
- 95x + 10
5. -4x - 4 - 2 - 5x
- -4x - 5x = -9x
- -4 - 2 = -6
- -9x - 6
6. 2x - 1 + 2x - 4 + y
- 2x + 2x = 4x
- -1 - 4 = -5
- 4x + y - 5
7. 5y - x + 2y - y + 5
- 5y + 2y - y = 5y + 1y = 6y
- -x + 6y + 5
8. -15 + 3y - 3x - 2y + 4x
- 3y - 2y = 1y = y
- -3x + 4x = 1x = x
- x + y - 15
9. 4 - 3y + 3x - 2x - y
- -3y - y = 4y
- 3x - 2x = 1x = x
- x + 4y + 4

1/5 because you need to simplify. Your simplify the fraction 20/100. The answer should be 1/5.
The slope is 2, because you subtract the points 3,17 from 7,25 to get 8/4/ Simplify that into 2.
