Answer:

The number of innings Brantley pitched is 7.

Step-by-step explanation:

We are given that the table shows the number of innings pitched by each of the Greenbury Goblins' starting pitchers during the Rockbottom Tournament below;

         Pitcher                           Number of innings pitched

          Calvin                                            11

          Thom                                             12

          Shawn                                            7

            Kris                                               3

         Brantley                                           x

Let the number of innings Brantley pitched be 'x'.

The mean of the following data set is given by the following formula;

          Mean = \frac{\text{Sum of all data values}}{\text{Total number of observations}}

                  8 = \frac{11+12+7+3+x}{5}

                 8\times 5 =33+x

                 40 = 33+x

                  x = 40 - 33 = 7

Hence, the number of innings Brantley pitched is 7.

3/4a−16=2/3a+14 PLEASE I NEED THIS QUICK and if you explain the steps that would be geat:) Thank youuuuuuu
Jlenok [28]

Answer:

360

Step-by-step explanation:

  • 3/4a - 16 = 2/3a + 14               ⇒ collect like terms
  • 3/4a - 2/3a = 14 + 16               ⇒ bring the fractions to same denominator
  • 9/12a - 8/12a = 30                  ⇒ simplify fraction
  • 1/12a = 30                               ⇒ multiply both sides by 12
  • a = 30*12
  • a = 360                                   ⇒ answer
