I believe you do it this way.

You multiply the den. with the whole number and add the num.

2 x 8 + 1 = 17. This now becomes 17/8 because you keep the same den.

1 x 7 + 2 = 9. This now becomes 9/7.

Now subtract 17/8 - 9/7

This equals 8/1, or, 8.

Solve for x:<br> - 11x + 32.5 &lt; 82
V125BC [204]

Answer:

x>-4.5

Step-by-step explanation:

- 11x + 32.5 < 82

Subtract 32.5 from each side

- 11x + 32.5-32.5 < 82-32.5

- 11x  < 49.5

Divide each side by -11. remembering to flip the inequality since we are dividing by a negative

-11x/-11 > 49.5/-11

x>-4.5

POSSIBLE POINTS: 10
ASHA 777 [7]

Step-by-step explanation:

I'm going to assume 50.25 was a typo error and it is $0.25 for each extra minute.

For a 10 minute phone call, the first 5 minutes cost $3 and the other 5 minutes cost $0.25 * 5 = $1.25. Altogether it costs $4.25.

For a 15.5 minute phone call, the first 5 minutes cost $3 and the other 10.5 minutes cost $0.25 * 11 = $2.75. Altogether it costs $5.75.

33.3% coverted into a decimle and fraction
valkas [14]
-- To change a percent into a decimal, move
the decimal point two places this way    <== .

                     33.3%  =  0.333 .

-- To change a percent into a fraction, remember
that the symbol  ' % '  means  ' /100 ' .

                     33.3 %  =  33.3/100 .

That fraction looks ugly, because it has a decimal in the numerator.
That's easy to fix.  Multiply top and bottom by  10, and you have

                                       333/1000 .
