What I did for this question is I set up ans equation. 5x-7 + 3x+11 = 180 and I added the Xs and and I added 11 to -7. Then I got 8x+4=180. I then "-4" on both sides and then divided 8 by 176. Getting X as 22. We now know X and we put 22 into the equation for D which is "3x+11" getting 77 degrees. Hope this helped!

Answer: The answer is 22,452

Which of the following are solutions to the equation. 6x^2-2x+36=5x^2+10x
Oduvanchick [21]

Answer:

x = 6

Step-by-step explanation:

Given

6x² - 2x + 36 = 5x² + 10x ( subtract 5x² + 10x from both sides )

x² - 12x + 36 = 0 ← in standard form

This is a perfect square of the form

(x - a)² = x² - 2ax + a²

36 = 6² ⇒ a = 6 and 2ax = (2 × 6)x = 12x, hence

(x - 6)² = 0

x - 6 = 0 ⇒ x = 6

Karen, James, Frank, and Dan were left an inheritance by their late grandfather. If Karen receives one-eighth of the inheritance
pashok25 [27]

Count what fraction receive Karen, James and Frank in total:

since

Karen receives - \frac{1}{8},

James receives - \frac{1}{4}=\frac{2}{8},

Frank receives - \frac{3}{8},

then \frac{1}{8} +\frac{2}{8} +\frac{3}{8} =\frac{1+2+3}{8}=\frac{6}{8} =\frac{2\cdot 3}{2\cdot 4} =\frac{3}{4}.

All inheritance is the whole 1, then for Dan remains 1-\frac{3}{4} =\frac{4}{4} -\frac{3}{4} =\frac{4-3}{4} =\frac{1}{4}.

Answer: Dan receives one quarter of the inheritance.

arsen [322]

Answer:

For the reasons mentioned in the explanation section, it is indeed a weak generalization:  

Step-by-step explanation:

  • No, there is not enough data provided on certain subjects' age, socioeconomic status, etc. that may have influenced the investing decision.
  • No, the survey isn't random, the study is irregular because each has a fair probability of expressing their true beliefs, here in this query it's written they've been told individuals are given actual medication, which may have contributed to the Hawthorne studies giving incorrect outcomes.
  • No, the amount isn't sufficient mostly on the premise of 28 subject areas with be provided oxytocin, and therefore only one test being performed should we not be able to determine the results to implement for certain persons including billions of populace, it would be a hurried generalization.
