Answer:

x = 4.4

Step-by-step explanation:

The ratios of corresponding sides are in proportion , that is

$\frac{x}{11}$ = $\frac{4}{10}$ ( cross- multiply )

10x = 44 ( divide both sides by 10 )

x = 4.4

5(3r+11)=85

raketka [301]

Answer:

r = 2

Step-by-step explanation:

Actually, there are 2 ways to solve this equation.

The first one:

5( 3r + 11) = 85

so here, you have to multiply 5 by ( 3r + 11) and maintain the 85

15r + 55 = 85... now put the like terms together. In other words, just transpose 55 to the other side. 

15r = 85 -55..... remember that the sign of 55 will change from positive to negative 

15r = 30.... now divide both sides by 15

15r/15 = 30/15

 r = 2

The second method :

5 ( 3r + 11) = 85...... divide both sides by 5

5 (3r + 11) / 5 = 85/5

3r + 11 = 17

3 r = 17 - 11

3r = 6 

r = 2

I hope this helps. If you don't quite get it, please go through until you get it. Have a nice day :-)

How to divide like that

Lady bird [3.3K]

Step-by-step explanation:

First you divide the numerator and the denominator by 10, it leaves you with 1500/21 , now you again divide the numerator and denominator by 3 and you get 500/7.

Remember, you ought to divide the numerator and the denominator only by the numbers which are their common factors or in a more easier way, you only divide them by a number which divides them both simultaneously.
