Answer:
The third one counting from the top.
Step-by-step explanation:
We have the inequality:
(-1/3)*(2x + 1) < 3
The first thing we need to do is isolate x on one side of the inequality.
First we can by -3 in both sides of the inequality, and remember, because we are multiplying by a negative number, the inequality sign changes its direction:
(-3)*(-1/3)*(2x + 1) > 3*(-3)
(2x + 1) > -9
Now we can subtract 1 in both sides:
2*x + 1 - 1 > -9 - 1
2*x > -10
Now we can divide by 2 in both sides:
2*x/2 > -10/2
x > -5
Then we should see a number line such that all the points at the right of -5 are colored.
The correct option is the third one, counting from the top.
Answer:
2 miles
Step-by-step explanation:
Their combined speed (speed of closure) is 80 mph + 40 mph = 120 mph.
120 mi/h = 120 mi/(60 min) = 2 mi/min
The distance between the trains at the 1-minute mark is ...
(1 min) · (2 mi/min) = 2 mi
They were warned when two miles apart.
Answer: 6.06 seconds

4 books
2(her gym clothes)+1(her lunch)=3
11(the total)-3(what we know)=8
8(the amount of room remaining)/2(the weight of each book)=4
4 books is the answer
Answer:
566,880
Step-by-step explanation:
First you have to understand what the problem is asking you. It wants you to find the difference between working for 40 years with a master's degree and 40 years with a bachelor's degree.
Next you need to do the math. You can use a calculator since these are pretty large numbers. Enter in the following to find how much you make working 40 years with a bachelor's degree: 68,103 * 40 Once you have calculated that, you should get 2,724,120. Now you need to find how much you earn working 40 years with a master's degree. Enter the following: 82,275 * 40 You should get 3,291,000.
Finally you need to find the difference. Type into your calculator the following: 3,291,000 - 2,724,120 You should end up with 566,880.
Hope this helps!
