Askirt requires 2 1/4 yards of material a matching blouse requires 1 3/8yards how much material should be bought

material = skirt+blouse

material = 2 1/4 + 1 3/8

get a common denominator of 8

material = 2 1/4*2/2 + 1 3/8

material = 2 2/8 + 1 3/8

material = 3 5/8 yds

2/3x + 7 = 29

step-by-step explanation:

two thirds = 2/3

plus a number = x

at least 29 = 29

there for you should get 2/3x + 7 = 29

- "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."
