Problem 11
<h3>Answer: h =
2A/b</h3>
------------------
Explanation:
We need to get h by itself. To do so, we first multiply both sides by 2. Then we divide both sides by b
A = (1/2)*b*h
2A = b*h
b*h = 2A
h = 2A/b

Problem 12
<h3>Answers:</h3>
- Equation: (n+2)/5 = 14
- Solution to that equation: n = 68
------------------
Explanation:
The number n is increased by 2 to get n+2
Then we divide by 5 to get (n+2)/5
This is set equal to 14 to get the equation (n+2)/5 = 14
Solving the equation would look like this
(n+2)/5 = 14
n+2 = 5*14 .... multiply both sides by 5
n+2 = 70
n = 70-2 .... subtract 2 from both sides
n = 68
================================================
Problem 13
<h3>Answer: Not a solution</h3>
------------------
Explanation:
We'll replace every copy of x with -3 and simplify
-2x + 5 > 13
-2*(-3) + 5 > 13
6 + 5 > 13
11 > 13
The last inequality is false because 11 is not greater than 13. Since the last inequality is false, this makes the first inequality false when x = -3.
Therefore, x = -3 is not a solution.
X^2-4x=-2x+24
x^2-2x=24
x^2-2x-24=0
(x-6)(x+4)
Proof:
-6+4=-2
-6*4=-24
Final answer: (x-6)(x+4)
Answer:
2
Step-by-step explanation:
you get 2 because 5 times 2 equals 10 and 6 times 2 equal 12. so you get 10/12
Answer: <em>Tax rate per dollar = .06536</em>
Given:
Amount needed from property tax = $915000
Value of assessed property = $14000000
Therefore, we'll compute tax rate per dollar as:
Tax rate per dollar = 
= 
= .06536
