Answer:
4x-5= 5 less than the product of 4 and a number. 4 (x-5)= The product of 4 and the difference of a number and 5. 4(x+5) = The product of 4 and the sum of a number and 5.
Step-by-step explanation:
I took the test online in K12 and when I reviewed it said that those are the correct answer.

Investment: cost of her education + salary as sales clerk during two years
Investment = 18,000 (2) + 20,000 = 36,000 + 20,000 = 56,000
Time to recover investment = 56,000/35,000 = 1.6
In less than two years, after she starts to work Niah will have recoverd her investment.
Answer:
(5, infinitysymbol)
Step-by-step explanation:
First solve the inequality. Subtract 2 from both sides.
x + 2 > 7
x > 5
So that is one way of writing the answer and it is hopefully kind of understandable. X>5 means all the numbers greater (bigger) than 5, forever to infinity.
Interval notation is a way of writing a set or group of numbers. Interval notation uses ( ) parenthesis or [ ] square brackets. Then two numbers go inside with a comma in between. The first number is where the set of numbers start and the second number is where the set ends. You always put parenthesis around the infinity symbol or negative infinity symbol. You only use a square bracket if the inequality symbols have the "or equal to" underline under the > or <.
So x > 5 in interval notation is:
(5, infinitysymbol)
This shows that 5 is not included in the solution; and all the numbers forever bigger than five are solutions as well.
