Solve the problem by writing and solving an equation.
a rectangular picture frame has a perimeter of 58 inches. the height of
the frame is 18 inches. what is the width of the frame?

11

Step-by-step explanation:

58=2 x length + 2 x height.

58-(18 x 2)=58-36=22

22/2=11

answer   download the app called socratic on your phoner:

step-by-step explanation:

- "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."
