The following table shows the number of innings pitched by each of the Greenbury Goblins' starting pitchers during the Rockbotto
Lady_Fox [76]

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.

Y=4x+1, 2x+y=37 substitution
VLD [36.1K]

Answer:

<em>x = 6 and y = 25 → (6, 25)</em>

Step-by-step explanation:

Substitute y = 4x + 1 to the equation 2x + y = 37:

2x + (4x + 1) = 37

(2x + 4x) + 1 = 37        <em>subtract 1 from both sides</em>

6x = 36           <em>divide both sides by 6</em>

x = 6

Pyt the value of x to the first equation:

y = 4(6) + 1

y = 24 + 1

y = 25

Which of the expressions below is equivalent to the expression: 42 + 32 – 13 × 2 + 38? a. 42 + 32 – (26 + 38) b. 42 + 32 – 13 ×
Anika [276]
Using PEMDAS, 42 + 32 - 13 * 2 + 38 can be simplified as,

C. 42 + 32 + 12 = 86

You can check this by inserting the given expression (42 + 32 - 13 * 2 + 38) into a calculator, which should also give you the same answer of 86.
