Susan' rope is three times as long as Fred's rope. Fred's rope is twice as long as Alison's rope. The total length of all three ropes is 36 meters. How long is Fred's rope?
S = 2F; F = 2A S + F + A =36
F = 2A and S = 2F => S = 4A
Don't understand
S = 4A, F = 2A 4A + 2A + A = 36
Okay so let S be the length of sally's rope
F - fred's A - alison's
okay
Woops meant not S = 2F, its S = 3F (Three times as long as fred's)
S = 3F F = 2A A S + F + A = 36 (total length)
S = 3F, but F = 2A => S = 3*2A = 6A
So you have: S = 6A F = 2A A = A (A is just A) S + F + A = 36 6A + 2A + A = 36
9A = 36 = > A = 4
F = 2A = 2*4 = 8 meters => Fred's rope is 8 meters long, please click on become a fan if I helped, thanks!
WHAT IS SUSAN'S LENGTH thANK yOU sUPERHERO, WILL DO
Susan's: S = 6A = 6 * 4 = 24 meters
