Answer:
x = 2
Step-by-step explanation:
BO = OD
they are apart of the same line segment with O as the midpoint of BD
since they're equal set equal and solve for x
7x + 4 = 18 subtract 4 from both sides
7x = 14 divide both sides by 7
x = 2

Answer:
Harry swims at 1.6 laps per minute and Larry swims at 1.8 laps per minute. Henry swims at a slower rate than Larry.
Step-by-step explanation:
i dont know for sure if this is right or not but i think it is. i mean for Henry the only number i have is 1.6 and so if that is going to be multiplied by x which is his minutes i would guess that that is the rate he is swimming at per minute. and as for larry, i took 4.5 (which is his laps) and divided it by 2.5 (which is his time) to get how many laps per minute he swims. i got 1.8. 1.6 is slower than 1.8 so therefore, i concluded that harry swam at a slower rate than larry.
