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 have an A for the test! How many students are there in that class?

Answers

Answer 1
Answer:

Answer:

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 = (x)/(2)

Now if one more student got A in test then the number of students who got A in test will be (x)/(2) +1

Now according to equation,

(2x)/(3) = (x)/(2) +1

(2x)/(3) - (x)/(2) = 1

Further solving

(4x-3x)/(6) = 1

x = 6

Hence the total number of students in class is 6.

Answer 2
Answer:

Answer:

9

Step-by-step explanation:

1/2x+2/3=2/3x

2/3=4/6x-3/6x=1/6x

x=9

Vanessa earns a base salary of \$400.00$400.00dollar sign, 400, point, 00 every week with an additional 5\%5%5, percent commission on everything she sells. Vanessa sold \$1650.00$1650.00dollar sign, 1650, point, 00 worth of items last week.What was Vanessa's total pay last week?

Answers

Answer:

Vanessa's total pay last week was $482.50.

Step-by-step explanation:

Given:

Vanessa earns a base salary of $400.00.

And every week with an additional 5 percent commission on everything she sells.

Vanessa sold $1650.00 worth of items last week.

Now, to find Vanessa's total pay last week.

Base salary = $400.00.

And then, to get the 5% commission on $1650.00.

5\%\ of\ 1650

=(5)/(100) * 1650

=0.05* 1650

=82.50

The commission = $82.50.

Now, to get the total pay of Vanessa's we add the base salary and the commission:

400+82.50

=\$482.50

Therefore, Vanessa's total pay last week was $482.50.

Solve -1 4/5 x= 9.
A) 5
B) 1/5
C) -5
D) -1/5

Answers

Answer:

C) -5

Step-by-step explanation:

-1 4/5 x= 9.

Change the left side to an improper fraction

(5*1+4)/5 = 9/5

-9/5 x =9

Multiply each side by -5/9 to isolate x

-5/9 * 9/5x = 9 * (-5/9)

x = -5

Answer:

C) -5

Step-by-step explanation:

-1 4/5 x= 9.

Change the left side to an improper fraction

(5*1+4)/5 = 9/5

-9/5 x =9

Multiply each side by -5/9 to isolate x

-5/9 * 9/5x = 9 * (-5/9)

x = -5
