The filled in dot means inclusive and the hallow dot means exclusive. For an inequality, inclusive will mean it can be equal to that number as well as being less or greater than. Exclusive means the opposite.
In terms of x, the number line shows that -2 <= x < 2.
Answer:
12.25 miles
Step-by-step explanation:
We can write a proportion to solve. Miles over time in minutes
1 hour = 60 minutes
1 hours 10 minutes = 60+10 = 70 minutes
3.5 miles x miles
--------------- = --------------
20 minutes 70 minutes
Using cross products
3.5 *70 = 20x
245 = 20x
Divide each side by 20
245/20 = 20x/20
12.25 =x
Jimmy can go 12.25 miles
The answer is A I am pretty sure. This is because in choice B, you would be dividing 7 and the sum of x + 5. In choice C you would not be multiplying 7 and the sum of x + 5. When he question asks for the product, it is asking for you to multiply. In choice D you would not just be squaring y, you would be squaring 2xy, which is not what we want. We only want to square y, therefore I believe the correct answer is A.
