Question

12+× =20 10+4+5= 50+10=

Answer 1

12+х=20. 10+4+5=50+10=60
х=20-12. непоняла
х=8

Answer 2

12 x ? = 20

To solve for the missing number, we can divide both sides of the equation by 12:

? = 20 / 12 ? = 1.67

So, the missing number is 1.67.

Now, to solve the rest of the equation:

10 + 4 + 5 = 19

Then,

50 + 10 = 60

So the final answer is:

19 + 60 = 79
