If 25 students took an exam and 4 of the students that took the exam failed, what percent of the students passed?
To find out how many students passed, we can subtract 4 from 25 and we will get a difference of 21.
The fraction
represents the number of students who passed the exam out of all the students.
To find out what percent of the students passed, we can turn
into a percent.
21 ÷ 25 = 0.84
0.84 × 100 = 84%
Therefore, 84% of the students who took the exam passed.
D - 21 ≥ 53
solve just like normally would using algebra.
add 21 to both sides
d ≥ 74
The fuel economy of the vehicle at 65 mph can be determined using the given equation. The fuel economy, y, can be solved by substituting the car's speed, x, to 65. Doing this, will result to y = 36.5988. Thus, the correct answer among the choices is that the fuel economy of the vehicle at 65 mph is about 37 mpg.
Answer is x=-1. Hope this helps!
