Just substitute in the values in 32>7x+4
if x=-1 ---->32>7(-1)+4---->32>3 which is true.It is a solution
if x=5--->32>7(5)+4--->32>39 which is false.it is NOT a soultion
if x=0---->32>4---->which is true .It is a solution
if x=4---->32>7(4)+4---->which is true. it is a solution
4/20 how I got my answer? Just times it by 2 or just any number you want! Which includes 3,4,5,6,7 Etc
If 4 is 100-84=16 % of his workout, 4 is 16/100 or 4/25 of his workout. If 4=4x/25, where x is his workout length, dividing by 4 and multiplying by 25 gives x=25, so Dave must run 25 laps total.
Its milli. It represents the smallest unit
domain refers to the X values so option A would be correct :)
