Step-by-step explanation:
![x + ( - 15) = 9](https://tex.z-dn.net/?f=x%20%2B%20%28%20-%2015%29%20%3D%209)
![x - 15 = 9](https://tex.z-dn.net/?f=x%20-%2015%20%3D%209)
![x = 9 + 15](https://tex.z-dn.net/?f=x%20%3D%209%20%20%2B%2015)
![x = 24](https://tex.z-dn.net/?f=x%20%3D%2024)
First, distribute to simplify the equation.
-3*w = -3w
-3*4 = -12
-3w + (-12) = -18
Now, isolate the variable.
-3w + -12 = -18
+12 +12
- 18 + 12 --> -6
-3w = -6
-3w/-3 = -6/-3 >>>>> w = 2
Answer: w = 2
Answer:
Step-by-step explanation:
To find a positive and a negative angle coterminal with a given angle, you can add and subtract 360°.
-135° + 360° = 225°
So first take triple 3 which would be 3+3+3 or 3x3.
Then take double 8 which would be 8+8 or 8x2.
So all you need to do is write it in the associative property.
So it would look like this:
(3x3)+(8x2)= 25
9 + 16
Because 3x3 is 9 and 8x2 is 16 so you just need to add them to get the product.
Answer:
D. 0.343
Step-by-step explanation:
You can see the first three options as 0.340 so if you substract this number with 0.343 the remainder is positive 3.
This strategy also can be applied to the number 0.3409 but in this occasion the result is different:
![0.343 - 0.3409 = 2.1\times 10^{-3}](https://tex.z-dn.net/?f=0.343%20-%200.3409%20%3D%202.1%5Ctimes%2010%5E%7B-3%7D)
That is small number but still is positive that's meaning that between 0.343 and 0.3409 the greatest value is 0.343 .
