Answer:
There is a mistake in Step 2. Maya distributed 3(x-10) as 3x+30, which is false. The correct step is: 6x+12 = 3x-30
Then solve for x
The answer is B. Maya made a mistake between Step 1 and Step 2 because she did not correctly distribute 3 to (x-10).
Answer: 3421.19
Step-by-step explanation:
look up cylinder formula and r= radius which is just the diameter cut in half
Answer:
<h2>16kg</h2>
Step-by-step explanation:
This problem is borers on elasticity of materials.
according to Hooke's law,<em> "provided the elastic limit of an elastic material is not exceeded the the extension e is directly proportional to the applied force."</em>

where F is the applied force in N
k is the spring constant N/m
e is the extension in meters
Given data
mass m= 24kg
extensnion=15cm in meters=
= 
we can solve for the spring constant k
we also know that the force F = mg
assuming 
therefore

We can use this value of k to solve for the mass that will cause an extension of 

Answer:
D). irrational numbers
Step-by-step explanation:
The irrational numbers are the set of number which can NOT be written as a ratio (fraction). Decimals which never end nor repeat are irrational numbers. Irrational numbers are "not closed" under addition, subtraction, multiplication or division.
first you put 12 over 100 and that is 12/100 and then simplify
