Answer:

Step-by-step explanation:

1.Distribute

12x - 66 + 15 =21

2.Add the numbers

12x-51=21

3.Add 51 to both sides of the equation

12x -51 +51 = 21+51

4.Simplify

12x=72

5. Divide both sides of the equation by the same term

12x/12 = 72/12

6. Divide the numbers

x=6

And you have your answer x=6

Please I need answer right now ppleassssee<br><br>D. -1/4+-2/3<br>with explanation pleaseeee​
Masja [62]

Answer:

1 - 1/3

Step-by-step explanation:

Since 1/2 * 2/3 = 1/3, it should be the case that 1/3 divided by 2/3 gives 1/2 and that 1/3 divided by 1/2 gives 2/3. To divide fractions, we multiply the numerator by the reciprocal of the denominator, where the reciprocal of a number just interchanges the numerator and denominator of the number.

Answer:

66 degrees! Hope it Helps!!!!

Step-by-step explanation:

So the total angle amount of a square is 360

x=32

Now pluggin x into the equation (6x-96)&(3x)
