Step-by-step explanation:
12 3/5 = 63/5
2 1/10 = 21/10
63/5 divided by 21/10 is equal to 63/5 multiplied by 10/21 which is equal to 630/105 = 6 <-- answer
For this case we have the following expression:

We must evaluate the expression when:

Substituting the values we have:

Equal signs are added and the same signs are placed.

Different signs are subtracted and the sign of the major is placed:

Finally we have to:

Answer:
Answer:
C) 7 and 3
Step-by-step explanation:
2x+4+8x-10=x²+15
10x-6=x²+15
0=x²-10x+21
0=(x-3)(x-7)
x=3 and 7
