Answer:
Your answer is 3x = 15
Step-by-step explanation:
3x = 15
Since 3 is being multiplied by x, we divide both sides by 3. 3x/3 cancels out, and you're left with x.
15/3 = 5
x = 5
This is my take using algebraic methods.
The first step to solving this problem is Multiplying In(x-1).
Answer:
Volume of sphere is 
Step-by-step explanation:
It is given that Hal says that volume of sphere is 
Volume of sphere is given by 
Now using 3.14 in place of 
Now volume of sphere is
Therefore volume of sphere when we use 3.14 in place of is
And the Hal likely error is he uses directly for calculation of volume.
Answer:
a. 18 b. 119°, 118°
Step-by-step explanation:
a. Given angles are vertical, so they are equal.
6a+11 = 2a+83
6a-2a = 83-11
4a = 72
a = 72/4
a = 18
b. Substituting the value of a in the given angles,
6a+11 = 6*18+11 = 108+11 = 119°
2a+83 = 2*18+83 = 36+83 = 118°
