Ahalf of a class and a half of a student got a on a test. if yet another student got an a, then two-thirds of the class would have an a for the test! how many students are there in that class?

6 students.

Step-by-step explanation:

let the number of students in class be x

Since Half of the class represents half of the students, therefore

Number of student who got A in test =

Now if one more student got A in test then the number of students who got A in test will be

Now according to equation,

Further solving

Hence the total number of students in class is 6.

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x

option b  

step-by-step explanation:

we know that

the distance from point n to lm in the figure is equal to the distance of the perpendicular line to lm that passes through the point n

so

the distance is equal to the segment no

> given problem

therefore

the distance from point n to lm is equal to
