2/3(x-2)=-2<br>how would I solve this

xeze [42]

Answer:

x =(5/3)

Step-by-step explanation:

The given expression is $\frac{2}{3(x-2)} = -2$

Now to simplify it,

The first step is to cross multiply.

So, the expression becomes

$\frac{2}{(-2)} = 3(x-2)$

or, -1 = 3x - 6

⇒ 3x = -1 + 6

⇒ 3x = 5 , or x =(5/3)

Maria had planned to walk 10 1/8 miles on wednesday, if she walked 7 2/8 miles in the morning how far would she need to walk in

Ugo [173]

Answer:

Distance Maria had to walk in the afternoon is $2\frac{7}{8}$

Step-by-step explanation:

Lets take that Maria walked $x$ miles in the afternoon.

Distance walked in the morning + distance walked in the afternoon = $10\frac{1}{8}$

⇒ $7\frac{2}{8} +x=10\frac{1}{8}$

$\frac{58}{8} +\frac{8x}{8} =\frac{81}{8}$

$\frac{58+8x}{8} =\frac{81}{8}$

$58+8x=81$

$8x=81-58\\$

$8x=23$

$x=\frac{23}{8}$

$x=2\frac{7}{8}$
