Answer:
between 2 an 3
Step-by-step explanation:
D/60 + D/50 = 2D/55 - 1/2
find common denominator ( 3300)
3300/60 = 55
3300/50 = 66
3300/55=60
so then you get 55D +66D= 60(2D)-1650
121D=120D-1650
D=1650 miles
check
1650/60 =27.5, 1650/50 = 33, 27.5 + 33 = 60.5 hours total
1650/55 = 30, 30 x 2 = 60
60.5-60 = 0.5 longer
so distance = 1650 miles
Answer:
The answer to your question is the letter B. y = -1/2x - 1
Step-by-step explanation:
Data
A (-6, 2)
slope = m = -1/2
Formula
y - y1 = m(x - x1)
x1 = -6 y1 = 2
Substitution
y - 2 = -1/2(x + 6)
Expand
y - 2 = -1/2x - 6/2
Simplify
y - 2 = -1/2x - 3
Solve for y
y = -1/2x - 3 + 2
Result
y = -1/2x - 1
Answer:
false
Step-by-step explanation:
1+2/5 = 5/5 + 2/5 = 7/5
Answer:
