Answer:

It will take him 75 minutes.

Step-by-step explanation:

Rule of three / cross-multiplication:

3 newspapers require 5 min

45 newspapers require x min

x = (45 / 3) * 5

x = 15 * 5

x = 75 min

Answer:

75 minutes

Step-by-step explanation:

3 newspapers = 5 minutes

45 newspapers = x minutes

45/3 = 15

3 x 15= 45 newspapers

5 x 15 = 75 minutes

Another way:

x= minutes

45/3= x/5

15=x/5

75=x

The correct answer is:  [C]:  " 5 " .
__________________________________________________________
                                →  " a = 5 " .
__________________________________________________________
Explanation:
__________________________________________________________ 

Given:  " a + 1 <span>− 2 = 4 " ; Solve for "a" ; 

4 + 2 = 6 ; 

6 </span>− 1 = 5 ;   →  a = 5 ;

To check our work:

5 + 1 − 2 = ? 4 ?? ;  

5 + 1 = 6 ; 

6 − 2 = 4.  Yes!

So the answer is:  [C]:  " 5 ". 
_________________________________________________________
                          →   " a = 5 " .

Answer:

2)  Equation 1 and Equation 2 have the same number of solutions.

Step-by-step explanation:

The two given equations are

1)  15x + 6 = 41                and                   2) 2x + 13 = 28

Solving both equations, we get

Solving (1) :   15x + 6 = 41 ⇒   15x  = 41 -  6 = 35

or, x = 35/15 ⇒ x = 7/3

Solving (2) :   2x + 13 = 28⇒   2x  = 28 -  13  = 15

or, x = 15/2 ⇒ x = 15/2

So, from above solutions we can say that Equation 1 and Equation 2 have the same number of UNIQUE solution.
