Q = m-a/x (solve for m)

DaniilM [7]

Answer:

m=a/x+Q

Step-by-step explanation:

Q=m-a/x

To solve this we need to isolate m so we will bring -a/x to the other side of the equal sign so it will become positive i.e. ax now will be written as a/x+Q=m

A half 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 h

svlad2 [7]

Answer:

6 students.

Step-by-step explanation:

let the number of students in class be<em> x</em>

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

Number of student who got A in test = $\frac{x}{2}$

Now if one more student got A in test then the number of students who got A in test will be $\frac{x}{2} +1$

Now according to equation,

$\frac{2x}{3} = \frac{x}{2} +1$

$\frac{2x}{3} - \frac{x}{2} = 1$

Further solving

$\frac{4x-3x}{6} = 1$

$x = 6$

Hence the total number of students in class is 6.
