Answer:

Necklace cost $144 and bracelet cost $48

Step-by-step explanation:

call x is the price of necklace, y is the price of bracelet

because necklace cost 3 time as much as the bracelet

=> 3x = y

A necklace and a bracelet cost $192

=> x + y = 192

=>set of equations

3x = y and x+y = 192

x= 3y and 3y + y = 192

=> y = 48 and x = 3 . 48 = 144

almond37 [142]

Answer:

1\frac{1}{6} = x

Step-by-step explanation:

\frac{x}{\frac{4}{3}} = \frac{7}{8} \\ \\ \frac{4}{3} \times \frac{7}{8} = \frac{28}{24} = 1\frac{4}{24} = 1\frac{1}{6}

Use multiplication [inverse of division] to figure this out.

* 1\frac{1}{3} = \frac{4}{3}

I am joyous to assist you anytime.
