Answer:

r=s(2b-a)

Step-by-step explanation:

You want isolate the variable, r, so we subtract a from both sides. We then have r over s equal 2b minus a. We we should multiply everything by s to cancel out the division. We come out with r equals s times 2b minus a.

the perimeter of a basketball court is 102 meters, and length is 6 meters longer than twice the width, what r length and width.

stepladder [879]

Perimeter = 2(l + w)

Thus,

102 = 2(l + w)

l = 6 + 2w

102 = 2( 6 + 2w + w)
102 = 12 + 4w +2 w
102 = 12 + 6w
90 = 6w

Thus, w = 15.

Length = 6 + 2w
= 6 + 30
= 36.

Thus, the length is 36 meters and width is 15 meters.

Since the common difference is 6, we can assume that the sequence is arithmetic, with rule
T(n)=6n+5 where T(1)=11
T(9)=6(9)+5=59
