10-12 please help, find the missing number and once you found the missing number and answered it you make sure it’s the solution
irinina [24]

10. Infinitely many solutions:

2(x-1)+6x=4(?-1)+2.

Simplify this equation:

2x-2+6x=4\cdot ?-4+2,\\ \\8x-2=4\cdot ? -2,\\ \\8x=4\cdot ?

When ?=2x, the equation becomes

8x=8x \text{ or } 0=0.

This equality is true for all x, thus the equation has infinitely many solutions.

11. The equation 5x-(x-2)=2x-(?) should have one solution x=-1.

First, simplify the equation:

5x-x+2=2x-?,\\ \\4x+2=2x-?,\\ \\2x+2=-?,\\ \\?=-2x-2.

This equation will have solution x=-1 when

?=-2\cdot (-1)-2=2-2=0.

Therefore, the initial equation is

5x-(x-2)=2x.

12. The equation -(x-8)+4x=2\cdot ?+x should have infinitely many solutions.

Simplify it:

-x+8+4x=2\cdot ?+x,\\ \\2x+8=2\cdot ?,\\ \\2(x+4)=2\cdot ?.

When ?=x+4, this equation will have infinitely many solutions.

How to add fractions? with unlike denominators
stellarik [79]

Answer:

The recipe calls for 19/12 or 1 7/9 cups.


Step-by-step:

In order to get this answer, we have to add all three fractions together. First, we have to find the LCM (Least Common Multiple) between the three denominators:

2: 2, 4, 6, 8, 10, 12

3: 3,6,9,12

4: 4,8,12

The LCM between these three denominators is 12.

4x3=12

2x6=12

3x4=12

You now multiply the numerator by the same number you multiplied by for the denominator in order to get 12:

3/4 becomes 9/12

1/2 becomes 6/12

1/3 becomes 4/12

We now add all the fractions together:

9/12+6/12+4/12= 19/12

We got 19/12 but the answer is an improper fraction so we turn it into a mixed number:

12x1=12 (7 remaining)

This is written as 1 7/12.

Hope this helps! :)
