Answer:
x=0
Step-by-step explanation:
3 = x + 3 + 6x
Combine like terms
3=7x + 3
Use order of operations to isolate x
3=7x + 3
-3 -3
0/7=7x/7
x=0/7 or 0
The 3 inside angles of a triangle need to equal 180 degrees.
You are given X and Y, so you would subtract both of those from 180 to find Z:
Z = 180 - 90 - 53 = 37 degrees
Suppose a pound of peanuts is priced at X, M&M is Y, and the equation is 6X+4Y=42.70 8X+5Y=55.27. [8X+5Y=55.27]*4-[6X+4Y=42.70]*5 is [32X+20Y=221.08] - [30X+20Y=213.5] X=3.79 Y=4.99
A) The attachment shows the equation of the best-fit line. It is approximately
.. test average = 89.7 -2.93*(hours playing games)
b) The slope indicates the expected drop in test score for each hour spent playing games
c) The y-intercept is the expected test score if no hours are spent playing games.
d) The correlation coefficient is -0.92, a significant negative correlation. One might expect that hours spent playing games indicates a lack of interest in school subjects or studying, hence a likelihood that test scores will be lower.
e) The equation predicts a test score of about 75 for someone who spends 5 hours a week playing video games.
