Like a first step bc. there is a denominator this will be more usefully eliminate it so what you can make it multiplied both sides by 2 
- so will get 

-2/2x +2*3/2 = 2(-4x+7)/2

(-2x +6)/2 = 2(-4x+7)/2   common denominator the 2 so make the numerators equal and solve for x 

-2x+6=-8x+14

6x=8

hope helped

Joseph and Wendy were catching tadpoles. At first Wendy caught nine times three more than Joseph caught. Joseph was upset and re
Dmitriy789 [7]

Answer:

Joseph caught 7 tadpoles

Step-by-step explanation:

Let the number of tadpoles caught by Joseph be x

The number of tadpoles Wendy caught will be ;

9(x + 3)

After Joseph was upset, he released half of Wendy’s tadpole and then six times as many as Joseph caught swam away leaving Wendy with only three tadpoles left;

Hence, mathematically;

9(x + 3)/2 - 6x = 3

Multiply through be 2

9(x + 3) - 12x = 6

9x + 27 -12x = 6

9x -12x = 6-27

3x = 21

x = 21/3

x = 7

The answer is:  " -5/3 " ;  or, write as:  " -1 ⅔ " .

Explanation:
_____________________________________________

   (-5/6) + (-5/6) = (-5/6) <span>− (5/6) ;  

------>  {since: "adding a negative" is the same a "subtracting a positive"} ; 

------> </span> (-5/6) − (5/6) = (-5 − 5) / 6  ;
  
                                  =   -10/6 =  (-10/2) / (6/2) ;

What does and 6 7/12 yards x 3 1/6 = ?
aleksandr82 [10.1K]
Well a<span>ll you have to do is turn one of the numbers from yards to feet or feet to yards, so you can accurately add it. Considering it would be easier to turn the yards to feet, you use the fact that, 1 yard is equal to 3 feet. So the 6 7/12 as feet is now 19.75 feet. So now you multiply them and 3 1/6 times 19.75 is 62.5416666535, and you can round this to just 63.</span>

A test is worth 50 points. Multiple- choice questions are worth 1 point, and short answer questions are worth 3 points. if the t
bagirrra123 [75]
Correct answer is C. 
m + 3s = 50 
the total number of questions is 20. since the paper is made of only multiple choice and short answer questions, the sum of the multiple choice and short answer questions should be 20.
since multiple choice is 'm' and short answer is 's'
then m + s = 20
but theres no option for that 
if we take the number of points 
points for 1 multiple choice question - 1
then points for m number of multiple choice questions = 1 * m = m
points for 1 short answer - 3
then points for s number of short answer question = 3 * s = 3s
then total number of points = m + 3s
and the total number of points = 50
therefore 
m + 3s = 50
this is the correct answer C.
