Mai's mother was 28 when Mai was born. Mai is now 12 years old. In how many years will Mai's mother be twice Mai's Age

noname [10]

Answer:

Step-by-step explanation:

Let x = the number of years

In x years, Mai's mother's age will be: 28 + x

and Mai's age will be: 12 + x

Then, 28 + x = 2(12 + x)

Distribute the 2 28 + x = 24 + 2x

Subtract 24 from each side 4 + x = 2x

Subtract x from each side x = 4

In four years, Mai's mother will be twice Mai's age.

<em>Check: </em>

28 + 4 = 2(12 + 4)

32 = 2 × 16

32 = 32

coldgirl [10]

Answer:

Step-by-step explanation:

The numbers are 6 and 2x, then:

1/6 + 1/(2x) = 7/24
1/3 + 1/x = 7/12
(x+3)/(3x) = 7/12
12(x+3) = 7*3x
12x + 36 = 21x
21x - 12x = 36
9x = 36
x = 4

The other number is 2*4 = 8

Step-by-step explanation:

We will prove by contradiction. Assume that $2^n + 1$ is an odd prime but n is not a power of 2. Then, there exists an odd prime number p such that $p\mid n$ . Then, for some integer $k\geq 1$ ,
