Answer:

-4x - 16y

Step-by-step explanation:

Given:

-4(3x - 2x + 4y)

Required:

Simplify

Solution:

To simplify, apply the distributive property by multiplying every term that is inside the brackets by -4

Thus:

-4*3x -4*-2x -4*+4y

-12x + 8x - 16y

Add like terms

-4x - 16y

2/3x+5=1 what is the solution to the equation shown?
Fudgin [204]

Answer:

x = - 6

Step-by-step explanation:

Given

\frac{2}{3} x + 5 = 1 ( subtract 5 from both sides )

\frac{2}{3} x = - 4

Multiply both sides by 3 to clear the fraction

2x = - 12 ( divide both sides by 2 )

x = - 6

Line CD passes through points C(3, -5) and D(6, 0) . what is the equation of the line CD in standard form?​
Kazeer [188]

Answer:

Option 2: 5x - 3y = 30

Step-by-step explanation:

Step 1: Find slope

(0-(-5))/(6-3) = 5/3

Step 2: Find <em>b</em>

y = 5/3x + b

0 = 5/3(6) + b

b = -10

Step 3: Write in slope-intercept form

y = 5/3x - 10

Step 4: Move x over

-5/3x + y = -10

Step 5: Multiply by -3 on both sides

5x - 3y = 30

And we have our final answer!

4 hours 30 minutes = ? Minutes
tigry1 [53]
The answer is:  " 270 minutes " . 
__________________________________________________________
        →  There are "270 minutes" in "4 hours and 30 minutes" .
__________________________________________________________
Explanation:
__________________________________________________________
Method 1):
__________________________________________________________
  Note:  60 minutes = 1 hour (exactly); 

30 minutes =   ?   hr ? ; 

→  (30 minutes) * (1 hr/ 60 minutes) ;

=
(30/60) hr = (3/6) hr  = (3÷3)/(6÷3) hr ;

=
" \frac{1}{2} hr " ;  

or; write as:  " 0.5 hr " .        
_________________________________________________________

So  "4 hours & 30 minutes" = 4 hours + 0.5 hours = 4.5 hours.

→   4.5 hours  =   ?  minutes ; 

The answer is:  " 270 minutes" .  4.5 hours * \frac{60 min}{1 hr}  ; 

       =  (4.5 * 60) minutes  =  " 270 minutes " .

→  The answer is:  " 270 minutes ".
___________________________________________________________
Method 2)
 
___________________________________________________________

    "4 hours and 30 minutes"  = <u>  ?  </u> minutes " . 
___________________________________________________________

→  " 4 hours   =  <u>  ?  </u> minutes " ; 

→   4 hr . * \frac{60 min}{1 hr}  =  (4 * 60) minutes  =  240 min. ; 

→  There are " 240 minutes in 4 hours" .

→  To find the number of "minutes" in "4 hours and 30 minutes" ;

→  we takes the number of minutes in 4 hours—which is "240 minutes"—and add "30 minutes" to that number; as follows:
   
           →  " 240 minutes + 30 minutes " ; 

to get:   " 270 minutes " . 
_______________________________________________________
 
      →  There are  "270 minutes"  in  "4 hours and 30 minutes" .
_______________________________________________________

The answer is:  
" 270 minutes " .
