Answer:
Step-by-step explanation:
I would begin by distributing the L. It will be easier in the end to do it this way. There are a couple of ways you can do this, but distribution is the easiest. After you distribute the L you have
T = 2L + LRS
Next subtract the 2L to get
T - 2L = LRS. Lastly, to isolate the R, divide away the LS to get
= R In that second term, the L's cancel each other out, leaving us with
= R
Work is attached. Hope it helps!
Answer:
x = 7
Step-by-step explanation:
Since the figures are similar then the ratios of corresponding sides are in proportion , that is
=
, substitute values
=
( cross- multiply )
48(7x - 9) = 60(4x + 4) ← divide both sides by 48
7x - 9 = 1.25(4x + 4) ← distribute parenthesis
7x - 9 = 5x + 5 ( subtract 5x from both sides )
2x - 9 = 5 ( add 9 to both sides )
2x = 14 ( divide both sides by 2 )
x = 7
