Answer:
Present value is $29,086.21.
Step-by-step explanation:
For Nina: 117.60 / 1414 = 0.083168317 For Ty: 148.50 / 1818 = 0.081683168 For Kim: 137.60 / 1616 = 0.085148515 Then Kim has the highest pay rate in dollars per hour with a total of 0.085148515 $ / h.
4x➕6(503-x)=2296
Distribute the 6 into the parentheses
Let x represent the students
503-x will represent the non-students
4x➕3018➖6x=2296
Then combine like terms
-2x➕3018=2296
Now since you move your constant your sign has to change as well,
-2x=2296➖3018
Then subtract
-2x=-722
Then divide both sides by -2
You are left with x=361
This represents the students
503➖361= 142 which equal the non-students
Therefore your answer is:
361=students
142=non-students
Hope this helps! :3
Solve: 2x - 3 = x^2 - 5 (at least, this is my interpretation of your 2 x -3).
x^2 - 5 - 2x + 3 + 0, or x^2 - 2x - 2 = 0
I will solve this by "completing the square:"
x^2 - 2x +(1)^2 - (1)^2 - 2 = 0, or x^2 - 2x + 1 - 1 - 2 = 0
This is (x-1)^2 = 3. Taking the sqrt of both sides, we get:
x-1 = plus or minus sqrt(3). Then x=1+sqrt(3) or x=1-sqrt(3). These are the two values of x for which 2x - 3 = x^2 - 5 is true.
Answer is 5(3a ⋅ 4) = (5 ⋅ 3a) ⋅ 4 (second one) ...this one is using <span>Associative Property of Multiplication</span>
