What is the solution of the inequality -0.4× -1.2> 0.8

Answers

x<-5

If I read the question correctly and x stands for a variable, and not multiplication, you can multiply each value by 10 to get whole numbers (or not, but whole numbers are easier to work with, and you get the same answer either way, I checked). This gives you


-4x -12>8


First you want to isolate x by adding 12 to both sides and getting. -4x>20. Then you divide both sides by -4, but when doing so, remember that when you divide by a negative number, you need to flip the sign. So then your answer is x<-5.

Blaine can make somewhere between 16 and 23 parking signs an hour. He needs 14 hours to set up his work station. About how many signs could he make in forty hours?A. 650 signs
B. 800 signs
C. 1,000 signs
D. 1,500 signs

Answers

Blaine could make approximately 650 signs in forty hours.

Calculate the working hours

Blaine needs 14 hours to set up his work station. So, out of the total 40 hours, he will have

=> 40 - 14 = 26 hours to actually work on making signs.

Calculate the minimum number of signs he can make

If Blaine makes 16 signs per hour, then in 26 hours, he will make a minimum of

=> 16 * 26 = 416 signs.

Calculate the maximum number of signs he can make

If Blaine makes 23 signs per hour, then in 26 hours, he will make a maximum of

23 * 26 = 598 signs.

Calculate the average number of signs he can make

To get a more reasonable estimate, we take the average of the minimum and maximum number of signs:

Average = (Minimum + Maximum) / 2

= (416 + 598) / 2  = 650 signs.

Hence the correct option is (a).
