Answer: 5
Step by step:
(3x+4)/2 = 9.5
3x+4 = 9.5*2
3x+4 = 19
3x = 19 -4
3x = 15
x = 5
Answer:
I will show all the steps to lead to the solution.
1) 10b = 5 (√c + 2) <---- starting equation
2) divide by 5 => 2 b = √c + 2
3) subtract 2 => 2b - 2 = √c
4) raise to the power 2 => (2b - 2)^2 = c, which is the expression given.
Now these are two equivalent forms:
1) extract 2 from the parentheses: c = 4 (b -1)^2
2) expand the parentheses: c = 4b^2 - 8b + 4)

Choice D
The run can be made 11 meters long
Answer: y=2x
Step-by-step explanation:
Let's solve for y.
Step 1: Add -2x to both sides.
2x−y+−2x=0+−2x
−y=−2x
Step 2: Divide both sides by -1.
-y/-1 = -2x.-1
y=2x
Therefore, the y=mx+b form of this question would be y=2x
