After one hour, one guy has covered 3mi and the other 4mi, which is in total 7, not 14
After 2 hours, one guy has covered 6mi and the other 8mi, which is 14mi
The algebraic way would be:
3x +4x = 14 *x being the hour
7x = 14
x =2
Answer:
Step-by-step explanation:
(7x-5)(6x+10)=0
42x + 70x - 30x - 50 = 0
82x = 50
x = 50/82
Answer:
D or 6
Step-by-step explanation:
Angle G is bisected if FGHI is a square. That being the case
7x + 3 = 45 Subtract 3 from both sides
7x = 45 - 3 Combine
7x = 42 Divide by 7
7x/7 = 42/7
x = 6
