Let the speed of El Toro be x mph and that of T Express be y mph.
Given : Speed of El Toro > Speed of T Express
i.e, x > y
Also, the difference in the speeds of El Toro and T Express is 5 mph.
So, the required equation is
x - y = 5
To determine the speed of a train, the speed of other is required.
The speed of El Toro = Speed of T Express + 5
The speed of T Express = Speed of El Toro - 5
Deposit = $1900
Amount After interest = $3875.79
% interest = 4%
Interest = 1975.79
Time For Interest Period
4/100 × 1900 × t = 1975.79
76 t = 1975.79

Step-by-step explanation:
Answer:
The correct option is option B. It has one solution, and it's x=-3
Step-by-step explanation:
We have the following system of equations:
5x+7 = 2y (1)
y-9x=23 (2)
Step 1: Solve for 'y' in equation (2):
y-9x = 23
y = 9x + 23
Step 2: Substitute in equation (1):
5x + 7 = 2y
5x + 7 = 2(9x + 23)
5x + 7 = 18x + 46
Step 3: Solve for x:
7 - 46 = 18x - 5x
-39 = 13x
x= -3
So the correct option is option B. It has one solution, and it's x=-3
