Brenda made 46 and 59 on her first two Biology tests and has one test remaining. The average on the three tests must be at least 65 for Brenda to pass the course. Write an inequality to represent this situation using s for the score on the last test.
\n" ); document.write( " $\"%28%2846+%2B+59+%2B+s%29%29%2F3\"$ => 65
\n" ); document.write( "Multiply equation by 3 to get rid of the denominator
\n" ); document.write( "46 + 59 + s => 3(65)
\n" ); document.write( ":
\n" ); document.write( "105 + s => 195
\n" ); document.write( ":
\n" ); document.write( "s => 195 - 105
