Answer:

8x

Step-by-step explanation:

3x + 8x are like terms which means they have the exact same variable.

To add like terms we add the coefficients which are 3 and 5.  

3 + 5 = 8  

We have 8 x's. So 3x + 5x = 8x.

In order to add terms, the variable part has to be exactly the same.

It's like saying 3 balls + 5 balls = 8 balls.

X > 5
x = 5 is not a solution because x is always greater than 5.

Crank
A) ( 25 / 100 ) * 100 = 25 m ;
b) ( 30 / 100 ) * ( 1205 / 100 ) = 36150 / 10000 = 3615 / 1000 = 3,615 km ≈ 3,62 km ;
c) ( 40 / 100 ) * 60 = ( 4 / 10 ) * 60 = 4 * 6 = 24 m^2 ;
d) 3 1 /3 = 10 / 3 ;
( 32 / 100 ) * ( 10 / 3 ) = 320 / 3 = 106,66 kg;
e) ( 1 / 10 ) ÷ 100 * 10 = ( 1 / 10 ) * ( 1 / 100 ) * 10 = 1 / 100 = 0,01 l ;

Good luck !
