Write in the form 1 : n the ratio 6 : 4

1 : 2/3

Step-by-step explanation:

to get 4 into n, we need to divide it by 6 as we did to the 6 to get it to be 1.

     6 : 4

÷6           ÷6

     1 : n

= 1: 2/3

did you get the answer?

1) the property is   ixi = a ⇔x = a   o x = -a

4(x-5)+3= 15⇒4x-20+3 = 15⇒4x-17= 15⇒4x = 15+17⇒4x = 32⇒x =32/4= 8

4(x-5) +3= -15⇒4x-20 +3 = -15⇒4x-17= -15⇒4x =-15+17⇒4x = 2⇒x =2/4= 1/2

the values are x =8 and x = 0,5
