The mileage is 33 miles per gallon.

Step-by-step explanation:

Miles per gallon = miles travelled / gallons consumed

= 973.50 / 29.5

= 33.

Arte-miy333 [17]

Answer:

18 like both.

Step-by-step explanation:

If there are 50 students and 3 like neither math or physics, then 47 of them either like one or both of the subjects. Adding up the 30 and 35, we get that 65 of the students like the two subjects collectively. Well that’s not right. We have overcounted the 65–47=18 students who like both subjects. Thus, 35–18=17 students only like physics.

Check: We have 3 students who like neither, 18 who like both, 17 who like just physics, and 30–18=12 who just like math. Adding them up, we have 18+17+12+3=50 students all togtether

ah i only need to know if its AND or OR! i already have the graphing done, if you could, please explain how you got AND/OR! than

Answer:

AND

Step-by-step explanation:

As a rule, a compound inequality such as this is an AND inequality. That is confirmed by the fact that ...

(a) the comparison symbols both point the same way, and

(b) the way they point is correct for the values on either end:

-2 < 3

If we were to reverse the comparisons so they were ...

-2 ≥ x > 3

we know right away that -2 > 3 is FALSE, so there will be no single value of x that will satisfy both inequalities. That is, if we interpret this as an AND inequality, its solution is the empty set.

On the other hand, if we interpret this as an OR inequality, then the solution set will be the union ...

(-2 ≥ x) ∪ (x > 3)

Because -2 > 3 is false, this form of the inequality (-2 ≥ x > 3) is not one you will usually see.*

As a rule, inequalities that have disjoint solution sets will not be written in this way. They will be written as separate inequalities, clearly identified as OR.

* I like to use this form because it is compact. When I use it, I do so with the understanding it is technically incorrect, and that the solution will be the union of the two solution sets. Not everyone who sees this "work" will understand this interpretation.

For example, |x| > 1 can be resolved to -1 > x > 1. This is technically incorrect, but can be seen as equivalent to two inequalities whose logic is OR. A technically correct resolution would identify this as equivalent to -x > 1 OR x > 1.
