Answer:
Step-by-step explanation:
This is segment addition in Geometry. Picture a straight line with endpoints A and C. B is a point stuck somewhere between them. The length of AC then is equal to the length of AB plus the length of BC. In algebraic terms:
AC = AB + BC. Filling in from the problem:
81 = 2x + 1 + 6x and combine like terms:
81 = 8x + 1 and subtract over the 1:
80 = 8x and divide by 8 to find
x = 10.
The answer to the question is B.
55 - 35 = 20
80 x 0.25 = 20
Therefore, you save money after 80 miles.
Answer:
D.
Step-by-step explanation:
Equation A: v = 4v + 5
Equation B: v = 3v + 5
---------------------------------
4v + 1 = 3v + 5
-3v
---------------------------------
v + 1 = 5
-1 -1
---------------------------------
v = 4
---------------------------------
v = 4(4) + 1 = 17
v = 3(4) + 5 = 17
Thus, your answer is D. 4v + 1 = 3v + 5.
