Formula: Distance = rate * time
570 = (R+(R-18))*3
570 = (2R - 18)*3
190 = 2R-16
208 = 2R
R = 104
Eastbound Train: 86mph
Westbound Train: 104mph
Answer:
yes
Step-by-step explanation:
Let the number = X
4x + 8x = 36
Simplify:
12x = 36
Divide both sides by 12:
x = 3
The number is 3
The number of hours Franco works must be greater than or equal to 32.
B
For each equation, set x to 0. A is correct because if x=o, then y will equal 38.910.
