Answer:
x = 3
Step-by-step explanation:
Use distributive property: a(b +c) =(a*b) + (a*c)
3(x + 6) = 27
3*x + 3*6 = 27
3x + 18 = 27 {Subtract 18 from both sides}
3x + 18 -18 = 27 - 18
3x = 9 {Divide both sides by 3}
3x/3 = 9/3
x = 3
Answer:
1.4x10^-7
Step-by-step explanation:
For Problem 6
First we would divide the first numbers together so 7.84 / 5.6 = 1.4
We then would add the exponenites together so -3+-4=-7
Leading our awnser to be 1.4x10^-7
Answer:
Step-by-step explanation:
Let the horizontal distance is x
<u>Use tangent to solve this:</u>
- tan 30° = 6/x
- x = 6 / tan 30°
- x = 10.4 mi (rounded)
90 because if his dog ate half his cards and benny had 45 left that means 45 times two equals 90 because the dog ate HALF of 90
Answer:
D
Step-by-step explanation:
The correlation coefficient r=-0.84 denotes that there is inverse relationship between x and y. It means that as the x values increase the y values decrease whereas as the x values decreases the y-values increases. Also, r=-0.84 denotes the strong relationship between x and y because it is close to 1. So, r=-0.84 denotes that there is strong linear relationship between x and y with smaller x values tending to be associated with larger y values.
