Then solve the equation.
6. the product of 6 and a number is 45.

x= 15

     2

x= 7 1/2   or   x=7.5

Step-by-step explanation:

6x=45

Divide both sides of the equation by 6.

6x÷6= 45÷6

Write the division as a fraction.

x= 45

      6

Reduce the fraction with 3.

x= 15

     2

x= 7 1/2   or   x=7.5

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
