Ben bowled 124 and 188 in his first two games. what must he bowl in his third game to have an average of at least 160?

What value of x is in the solution set of 4x - 12 s 16 + 8x? -10 -9 -8 -7

Which sum or difference identity would you use to verify that cos (180° - q) = -cos q? a.) sin (a -b) = sin a cos b – cos a sin b b.) cos (a -b) = cos a cos b – sin a sin b c.) cos (a -b) = cos a cosb + sin a sin b d.) sin (a + b) = sin a cos b + cos a sin b
