Which steps could be used to solve this equation?

Mathematics
1 answer:
Nesterboy [21]3 years ago
7 0

Answer:

answer is option B

Step-by-step explanation:

ok the equation is 2/3 x +9 = 15

if we substract 9 from both sides it becomes, 2/3x +9-9 = 15-9.

2/3x = 6

now if we multiply both sides by the reciprocal of 2/3 ( reciprocal means flip it for example receprocal or 2/3 is 3/2)

we multiply both side by reciprocal ie,

2/3 x 3/2 which is 1 because the 3 on the numerator cancels with the 3 on the deniy and the 2 on the numerator cancels with 2 on the denominator. then you are left with only x on the left side.

x = 6 x 3/2 = 18/2 = 9.

I have one dozen eggs and I discover hot only 1/3 of the broken and I need use 1/6 how many I have left
zhenek [66]

Answer:

X=2

Step-by-step explanation:

From the question we are told that:

Total eggs n=12

Broken eggs n_b=1/3n=4

Used eggs n_u=1/6n=2  

Generally the equation for amount  of eggs left X is mathematically given by

12=X+n_b+n_u

12=X+4+2

X=\frac{12}{6}

X=2

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 " .
