Answer:
1/14
Step-by-step explanation:
Odd numbers: 5, 7, 9
3/7 × 1/6
1/14
<em>Answer:</em>
<em><u>X = 80</u></em>
<em>Step-by-step explanation:</em>
<em>Subtract </em><em>"5"</em><em> from both sides,</em>
<em>3x + 5 - 5 = 245 - 5</em>
<em><u>Simplify,</u></em>
<em>3x = 240</em>
<em><u>Divide both sides by </u></em><em><u>"3"</u></em><em><u>,</u></em>
<em>3x/3 = 240/3</em>
<em>X = </em><em>80</em>

<span>46 <= grade < 96
First, let's write the equation for the lower limit that the student must get for a B.
(x + 92 + 82 + 88 + 92)/5 = 80
Multiply both sides by 5 giving
x + 92 + 82 + 88 + 92 = 400
Subtract 92, 82, 88, 92 from both sides
x = 400 - 92 - 82 - 88 - 92 = 46
So the student has to get 46 or higher on the test to make a B.
Now let's compute the upper limit
(x + 92 + 82 + 88 + 92)/5 < 90
Multiply both sides by 5
(x + 92 + 82 + 88 + 92) < 450
Subtract 92, 82, 88, 92 from both sides
x < 450 - 92 - 82 - 88 - 92 ) = 96
So the student has to get a grade of less than 96 to get a B.</span>
