<em>Replace all occurrences of x with y + 3 in each equation.</em>
<em>Replace all occurences of x in 6x - 5y = 15 with y + 3.</em>
<em>6 (y+3) -5y = 15</em>
<em>x = y + 3</em>
<em>Simplify 6 (y + 3) - 5y.</em>
<em>Simplify each term.</em>
<em>Apply the distributive property.</em>
<em>6y + 6 · 3 - 5y = 15</em>
<em>x = y + 3</em>
<em>Multiply 6 by 3.</em>
<em>6y + 18 - 5y = 15</em>
<em>x = y + 3</em>
<em>Subtract 5y from 6y.</em>
<em>y + 18 = 15</em>
<em>x = y + 3</em>
<em>Move all terms not containing y to the right side of the equation.</em>
<em>Subtract 18 from both sides of the equation.</em>
<em>y = 15 - 18</em>
<em>x = y + 3</em>
<em>Subtract 18 from 15.</em>
<em>y = -3</em>
<em>x = y + 3</em>
<em>Replace all occurences with y with -3 in each equation.</em>
<em>Replace all occurences of y in x = y + 3 with -3.</em>
<em>x = (-3) + 3</em>
<em>y = -3</em>
<em>Add -3 and 3.</em>
<em>x = 0</em>
<em>y = -3</em>
<em>The solution to the system is the complete set of ordered pairs that are valid solutions.</em>
<em>(0,-3)</em>
<em>The result can be shown in multiple forms.

Range 10
not positive on the 6.6 but the rest should be good
Answer:
s = ≥34
Step-by-step explanation:
Jim is correct because the ratios need to compare with the total amount of people surveyed. 55, 80, and 65 are numbers that don't fit in and don't tell the overall ratio. You can tell this by writing it as a fraction.
Ex: 35:100 = 35/100. This literally means 35 out of 100 people exercise in the morning.
Hope this helps! If you have any questions, just ask!
