Omar is born weighing 8 pounds, 3 ounces. the doctor says he should again about 5 ounces each week for the next 4 weeks. how much should omar weigh after 4 weeks?

8 lbs 3 oz + 4 * 5 oz  

8 lbs 3 oz + 20 oz

8lbs 23 oz     there are 16 oz in a lb   (23-16 = 7)

8 lbs + ( 1 lbs 7 oz)

9 lbs 7 oz

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."

wth is with the little mtn top and what are you talking about like fix your words and accually make sence with them and i like was in a completly different question like three times like it seems like your ilitteret
