Answer:

$\boxed {x = 0}$

Step-by-step explanation:

Solve for the value of $x$ :

$3 = x + 3 - 5x$

-Com bine like terms:

$3 = x + 3 - 5x$

$3 = -4x + 3$

-Switch the equation around:

$3 = -4x + 3$

$-4x + 3 = 3$

-Subtract 3 on both sides:

$-4x + 3 - 3 = 3 - 3$

$-4x = 0$

-When you are dividing $0$ by a positive or negative integer, it would obviously be $0$ :

$\boxed {x = 0}$

Therefore, the value of $x$ is $0$ .

What is the value of X if 9^x^-^1-2=25?

nadezda [96]

Answer:

$\frac{5}{2}$

Step-by-step explanation:

First, add two to both sides to get $9^{x-1}=27$

There are two ways to solve this from here

Think about what power you would have to raise 9 to to get to 27. $9^{\frac{1}{2}}$ = 3 and $3^3=27$ . So, multiplying the powers (because it is a power to a power) you get $9^{\frac{3}{2}}=27$ . This means that $x - 1 = \frac{3}{2}$ or x = $\frac{5}{2}$ .
Take the log of both sides.

This gives us $\log_9(27)=x-1\\\log_9(27)+1=x\\\log_9(3^3)+1=x\\3\log_9(3)+1=x\\3(\frac{1}{2})+1=x\\\frac{3}{2}+1 = x\\\\\frac{5}{2} = x$

At Lesile's party 1/4 of the people had long hair. 1/2 of the people were boys, and 1/4 of the girls had short blonde hair. None

dybincka [34]

Answer:

4 girls have short red hair

Step-by-step explanation:

Total number of guests at the party is 32

1/2 of the guests are boys

The number of girls with long hair is

= 32×1/4

= 8 girls.

The number of girls with short blonde hair is:

= 16×1/4

= 4 girls

Therefore, we apply the formular below to calculate the maximum number of girls with short red hair.

Total number of girls- ( girls with long hair+ girls with short blonde hair)

= 16-(8+4)

=16-12

= 4

Thus, 4 girls have short red hair
