The answer should be D because when you solve all of these, A,B,and C all equal 338,688 while D would equal 28,236. this is because D is adding the third 12 instead of multiplying.

How many solutions does the equation have?
Elina [12.6K]

9514 1404 393

Answer:

  1 solution

Step-by-step explanation:

The coefficients of d are different on the two sides of the equation (3d vs 6d), so the equation has one solution.

__

Dividing by 3 gives ...

  d +11 = 2(d +33)

  d + 11 = 2d + 66

Adding -d-66 to both sides gives ...

  -55 = d . . . . . . the one solution

Write a function rule for the table.
Pavlova-9 [17]
The correct answer is:  [C]:  " p = 6.25 h " .
______________________________________________________
Explanation:  
______________________________________________________

It is clear that "pay" is a function of "hours worked" ; 

So, we can eliminate:  "Choice [B]:  " h = <span>6.25p" .
______________________________________________________
Try, Choice [A]:  " </span>p = h + 12.5 " ; and 14.50 ≠ 12.50 ; (12.50 is the amount shown in the table.  So, we can already eliminate "Choice [A]".
<span>_____________________________________________
Now that we have eliminated choices [A] and [B]; 

we are left with choices:  [C] and [D]:
_____________________________________________
Consider choice [C]:  " </span><span>p = 6.25h " ;  
</span>   when "h = 2" ; does: "p = 12.5" (as shown on table)?? ; 

i.e. " 12.5 =? 6.25 * (2) ?? Yes!  This choice is a POSSIBILITY.
_____________________________________________
Consider choice [D]:  " p = 12.5h" .

When "h = 2, does "p = 12.5" (as shown on table)?  No!  
   → We can see from this very answer choice
        (the equation itself) that when "h = 2" ;
the value of "p" is DOUBLE [that of "12.5"].
 ________________________________________________
The correct answer is:  Answer choice:  [C]:   " <span>p = 6.25 h " .

Answer:

$1.30

Step-by-step explanation:
