Add up the amount of miles she actually reached to
2.4 + 3.1 =
5.5 = miles already traveled
And then subtract it from the 8 mile trail
8 - 5.5 =
2.5 miles
About 2.5 or 3 miles (rounded to the tenth or whole number?)
3(x)+10= 2x3+2x6
°°° Let's see -
Solve for x - BUT, before we do that, I want to look at the right side of the equal sign: I believe the 'x' on the right side '2 x 3 + 2 x 6' is actually a multiplication sign, so we'll replace that with a proper x so that we don't get confused.
°°° Rewrite the equation -
3 (x) + 10 = 2 × 3 + 2 × 6
°°° Simplify both sides of the equation -
3x + 10 = (2) (3) + (2) (6)
°°° Simplify again (Yes, again) -
3x + 10 = 6 + 12
3x + 10 = (6 + 12) (Combine Like Terms)
3x + 10 = 18
°°° Subtract 10 from both sides -
3x + 10 - 10 = 18 - 10
3x = 8
°°° Divide both sides by 3 -
3x / 3 = 8 / 3
x = 8 / 3
°°°FINAL ANSWER°°° -
x = 8 / 3
