What is 3/-4 ÷ (-2 1/3) ​

I’m assuming these are fractions.
•Convert (-2 1/3) into a improper fraction, -2 x 3 + 1= -7, -7/3 is the improper fraction.
• Dividing Numbers that both have negative signs equals positive.
So now it is 3/4 ÷ 7/3.
• Do the reciprocal, it’s now 3/4 x 3/7.
• Multiply
3/4 x 3/7= 9/28

I hope this helps and I did not make any mistakes solving the equation.

Answer:

9/28

Step-by-step explanation:

First transform -2 1/3 to -7/3. Then find the reciprocal of -7/3 which is -3/7. Multiply that to 3/-4 which becomes -9/-28 which equals 9/28.

At the beginning of a basketball season, the panthers won 20 games out of 50 games. At this rate, how many games will they win i
Anton [14]

Answer:

They will win 48 games in a 120 game season.

Step-by-step explanation:

The team won 20 games out of 50; that is a 20:50 ratio, that is equal to x:120.  x is the amount of games won in the 120 game season.

Set up the ratios like this:

\frac{20}{50} = \frac{x}{120}

cross multiply the numerators and denominators to get this:

20*120 = 50x

solve for x:

2,400 = 50x

x = 48

 m∠A = 42 and m∠C = 57. Find m∠B.<br>A. 81<br><br> B. 99<br><br> C. 132<br><br> D. 147
faltersainse [42]
A.
because the total distance of every triangle 180. Add the two other angles so 42+ 57 =99. Then you have to subtract those two combined angles to find the missing one from the total distance, which is 180. 180-99=81. the answer is A. 81
