5t + 15s = 211.25
t = s + 15.25

Substitute the second equation into the first equation for the t.
5(s + 15.25) + 15s = 211.25
Distribute the 5
5s + 76.25 + 15s = 211.25
20s + 76.25 = 211.25
Subtract 76.25 from both sides
20s = 135.00
Divide both sides by 10
s = 6.75
t = 6.75 + 15.25
t = 22.00

CHECK
5t + 15s ?=? 211.25
5(22.00) + 15(6.75) =
$ 211.25

fgiga [73]
I'm thinking maybe x is supposed to represent the number of tasks completed because it states Shelly earned 90 points on each task.  Then when put together it may look like this, let's say there are 4 tasks= Ex.90 times the 4 tasks minus 20 points which would total the points Terrence's has earned. So i believe x is the total tasks. Hope I didn't make it confusing...

For which rational expression is 8 an excluded value ? check all that apply
denis23 [38]

<u>Answer:</u>

The correct answer options are C. \frac{x^2+5}{x-8} and D. \frac{x^2-x-56}{x^2-64}.

<u>Step-by-step explanation:</u>

The values which make the denominator equal to zero are called the excluded values.

Here, we can substitute 8 for x and check if it makes the denominator 0.

\frac{x-8}{x+8} = \frac{8-8}{8+8} =\frac{0}{16} =0

\frac{x-2}{x^2-4} = \frac{8-2}{8^2-4} =\frac{6}{60} =\frac{1}{10}

\frac{x^2+5}{x-8} = \frac{8^2+5}{8-8} =\frac{69}{0}

\frac{x^2-x-56}{x^2-64} = \frac{8^2-8-56}{8^2-64} = \frac{0}{0} =0

\frac{8x^2-2}{x^2-16} = \frac{8(8)^2-2}{8^2-16} =\frac{510}{48}
