George wants to buy a $200 bike by the end of the summer. he decides to do odd jobs to earn the money for the bike. he mows lawns, washes cars, and waxes cars. his rates are $10 for a mowed lawn, $8 for a washed car, and $4 for a waxed car. by the end of june, george has mowed 10 lawns, washed 8 cars, and waxed 6 cars.

$10 mowed lawn x 10 lawns = $100

$8 washed car x 8 cars = $64

$4 waxed car x 6 cars = $24

$100 + $64 + $24 = $188

step-by-step explanation:

2-7=-5

7-2=5

when you combing like terms for ech expression, 5 and -5. these numbers are not equal to each other.

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
