No because a negative times a negative = a positive and they left the 12/13 negative when it should’ve been changed to positive

7w = 87 ; w = 12 I need help
Marysya12 [62]
I don't know what the question is, and I'm guessing that you don't either. All I see here is two statements that disagree with each other. If 7w=87. then w is not 12. And if w=12 then. 7w is not 87.

Burka [1]

Answer:

C) 28.5 home runs

General Formulas and Concepts:

<u>Pre-Algebra </u>

Order of Operations: BPEMDAS

  1. Brackets
  2. Parenthesis
  3. Exponents
  4. Multiplication

  • Left to Right

Equality Properties

  • Multiplication Property of Equality
  • Division Property of Equality
  • Addition Property of Equality
  • Subtract Property of Equality

Step-by-step explanation:

<u>Step 1: Define </u>

y = home runs

x = hits

[Best Line of Fit] y = 0.15x - 1.5

<em>We can use this to predict the average of the scatter plot. </em>

hits = x = 200 times

<u>Step 2: Solve for </u><em><u>y</u></em><u> home runs</u>

  1. Substitute [BLF]:                     y = 0.15(200) - 1.5
  2. Multiply:                                  y = 30 - 1.5
  3. Subtract:                                 y = 28.5

Remember that this is only a <em>prediction.</em> Actual data can vary. The best line of fit tells us that if a player hits 200 times, we would get approximately 28.5 home runs.
