Answer:

AB = 3

Step-by-step explanation:

Since AB is a perpendicular bisector then Δ is isosceles and AD = AC, that is

4x - 1 = 2x + 3 ( subtract 2x from both sides )

2x - 1 = 3 ( add 1 to both sides )

2x = 4 ( divide both sides by 2 )

x = 2

Hence AB = x + 1 = 2 + 1 = 3

Javier drove 45 miles. This represent 60% of his entire trip. What is the total number of miles in Javier’s trip

Andrews [41]

60% of trip = 45 miles

let total trip distance = l

60% is given by multiplying by 0.6

So;

0.6l = 45 \\ \\ l = \frac{45}{0.6} \\ \\ \boxed{l = 75}

Your answer is 75 miles
