Answer:

1) 4T+T=125

2) Rhonda drove 25 miles

and Jamie drove 100 miles

Step-by-step explanation:

1) Rhonda drove = T

Jamie drove = 4T

4T+T=125

2) 5T=125

T=125/5

T=25

So Rhonda drove T = 25

And Jamie drove 4T = 100

Help? pre cal, will give points
Viktor [21]

Steps to solve:

5x² = 15x

~Subtract 15x to both sides

5x² - 15x = 15x - 15x

~Simplify

5x² - 15x = 0

~Factor left side

5x(x - 3) = 0

~Factors equal 0

5x = 0 and x - 3 = 0

___________

~Simplify 5x = 0

5x/5 = 0/5

x = 0

~Simplify x - 3 = 0

x - 3 + 3 = 0 + 3

x = 3

___________

Thus, the correct answer is 0, 3.

___________

Best of Luck!

Step-by-step explanation:

x + y = 9. => 2x + 2y = 18.

2x + 2y = 18

- (2x - 3y = -12)

=> 5y = 30, y = 6.

Therefore x + (6) = 9, x = 3.

The solution is x = 3 and y = 6.
