The four inequalities have the following solutions:
A.
B.
C.
D.
Try to match these conditions with your set. For example, option A is surely wrong, because it claims that we only want number which are less than 10, but 10 itself is in our set. Similarly, option B is wrong, because it only allows numbers greater than or equal to 6, but our set contains 5.
Applying this logic, try to see if the answer is C or D!
Hey there! I'm happy to help!
We see that the ladder reaches a height of 6m from the ground while being 2.4 m from the wall. The ratio of the height to the length from the wall is 6:2.4 which can actually just simplify to 2.5 because 6m to is 2.4*2.5.
This person is 80 cm from the ladder's base. We just saw that you can take the distance from the wall (in this case, our wall is the human as the human is touching the height) and multiply it by 2.5 to find the height of the ladder at that specific point. So let's do that.
80*2.5= 200
We are looking for meters though. Since there are 100 centimeters in a meter, this is just going to be 2 meters.
Have a wonderful day! :D
When you divide 4.24 and 40 you will get 0.106
The correct multiple choice questions (x) are 4 points each.
The correct word problems (y) are 8 points each.
Lorenzo needs AT LEAST 50 points.
Put all that information into an inequality and you get:
4x + 8y ≥ 50
