If you walked 5 miles down a trail and then walked 2 1/4 miles back, how many miles away are you from your starting point?

lyudmila [28]

First lets figure out 2 and 1/4 as a decimal
2 and 1/4 = 2.25
So now we subtract
5 - 2.25 = 2.75
She is 2.75 miles away from her starting point

Solve |2x - 6| > 10

inn [45]

ANSWER

{x|x < -2 or x > 8}

EXPLANATION

The given absolute inequality is

$|2x - 6| \: > \: 10$

By the definition of absolute value,

$(2x - 6)\: > \: 10 \: or \: \: - (2x - 6)\: > \: 10$

Multiply through the second inequality by -1 and reverse the inequality sign

$2x - 6\: > \: 10 \: or \: \: 2x - 6\: < \: - 10$

$2x \: > \: 10 + 6\: or \: \: 2x \: < \: - 10 + 6$

Simplify

$2x \: > \: 16\: or \: \: 2x \: < \: -4$

Divide through by 2

$x \: > \: 8\: or \: \: x \: < \: -2$
