<span>According to astronomers a light year riddle is the distance traveled by light moving in a vacuum in the course of one year</span>
Yes it does, it is proportional because it increases by the same amount at a constant time (which is each week's paycheck). The constant is the 150. i may be wrong sorry if so.
What he or she said up there^^^^^^^
Perimeter is the total length of all sides. 72 divided by 4 equal sides of a square will give you the value of a. 72 divided by 4 is 18. The value of a is 18 yards.
Y=3
to solve this you just substitute 4 in for x into the equation and solve for y. since negative 3 plus 7 is 4, y=4
