in a class, 2/7 of the students have blue eyes. if there are 35 students in the class, how many have blue eyes?

2 answers:

7 0

The answer is: 10 (ten).

Ten (10) students in the class have blue eyes.
_________________________________________________________

(2/7)* (35) = (2/7) * (35/1) ;

the "7" cancels to a "1"; and the "35" changes to a "5" ; since "35÷7= 5" ;
___________________________________________________________
(2/1) * (5*1) = (2*5)/(1*1) = 10/1 = 10 .

35/7 = 5
5 times 2 = 10
That means if 35 students are in the classroom, 10 will have blue eyes.

A linear inequality to represent the algebraic expression is given as 492.46 - x ≥ 500

<h3>Linear Inequality</h3>

Linear inequalities are inequalities that involve at least one linear algebraic expression, that is, a polynomial of degree 1 is compared with another algebraic expression of degree less than or equal to 1.

In this problem, her minimum balance must not decrease beyond $500 or she will pay a fee.
