2x-y=3
use the substitution method
2(2)-y= 3
4-y= 3
move 4 to the other side
sign changes from +4 to -4
4-4-y= 3-4
-y= 3-4
-y=-1
mutiply both sides by -1 to get +y
(-1)(-y)= (-1)(-1)
y= (-1)(-1)
Answer: y= 1
Answer:
400 miles
Step-by-step explanation:
Distance = rate * time
Distance = 50 miles per hour * 8 hours
Distance = 400 miles
Answer:
r = 6 mph and f = 11 mph
Step-by-step explanation:
Representations:
1) speed of faster cyclist: f = r + 5
2) speed of slower cyclist: r
Distances covered:
(r + 5)(5 hr) + r(5) = 55 mi (total distance covered)
Then 5r + 25 + 5r = 55, or, after reducing this equation:
r + 5 + r = 11, or
2r = 6
Then r = 6 mph and f = 11 mph
