From Question,
60/100 * x = 12
or, x = 12/0.6
or, x=20 Ans:
Answer: For this one, I'll use y=mx+b because that equation make the most sense in this scenario.

Answer:
2 3/8 (2.375)
Step-by-step explanation:
You can substitute m with 1/4, giving you the equation 2(1/4^2) + 9(1/4). You can then solve for the answer.
How to solve:
2(1/4^2) + 9(1/4)
2(1/16) + 9/4
1/8 + 9/4
1/8 + 18/8
19/8
2 3/8 (2.375)

Answer: x=20
Step-by-step explanation:
When solving for a 5-sided pentagon we know the degrees add up to 540 degrees
Step 1: Write all variables given into an equation equal to 540 degrees
4x+5+7x+4x+10+6x+10+5x-5=540
I did not include the parenthesis because when I write out my equation they all share the same variable meaning they are like terms that can be combined.
Step 3: Combine like terms
26x+20=540
Step 4: Isolate the variable
By combining like terms like subtrating 20 to both sides. Always remember what you do to one side you must do to the other.
26x=540-20
Step 5:Continue to isolate the variable
26x=520
x=520/26
x=20
Final Answer
x=20 :) Hope that helped
