-28 = 22 - 5x

-28 -22 = 22 -22 -5x

-50 = -5x

-50/-5 = -5x/-5

10 = x

x = 10

To solve the equation we have to rearrange the terms i.e. like terms on one side

$-28 = 22 - 5x$

Subtracting 22 from both sides we get

$-28 -22 = 22-5x - 22$

$-50 = -5x$

Divide both sides by -5 we get

$\frac{-50}{-5} = \frac{-5x}{-5}$

On simplifying we get

$x =10$

Hence, x= 10 is your answer

Hope this will help

Answer:

Infinitely Many
Distributive Property

Step-by-step explanation:

8x + 2(x - 7) = 7x + 3x - 14

8x + 2x - 14 = 7x + 3x - 14 Distributive property.

10x - 14 = 10x - 14 Combine the like terms.

-14 = -14 Subtraction.

0 = 0 Addition.

Since the statement 0 = 0 is true regardless of the value of x, there is infinitely many solutions.

Rewrite 19/5 as a mixed number.<br> 1. 4^2/5<br> 2. 3^4/5<br> 3. 5^3/4<br> 4. 4^1/5

Nadusha1986 [10]

Answer:

3 4/5

3 1/5
16 1/5
31 1/4
4/5

Step-by-step explanation:

An improper fraction is converted to a mixed number by doing integer division and expressing the remainder as a fraction with the divisor as the denominator.

... 19/5 = (3·5 +4)/5 = 3 4/5

The expressions involving exponents are evaluated to mixed numbers according to the Order of Operations. The exponent is evaluated before division, so ...

1. 4^2/5 = (4^2)/5 = 16/5 = 3 1/5

2. 3^4/5 = (3^4)/5 = 81/5 = 16 1/5

3. 5^3/4 = (5^3)/4 = 125/4 = 31 1/4

4. 4^1/5 = (4^1)/5 = 4/5

_____

If you intended fractional exponents, according to the Order of Operations, you need to put that fraction in parentheses. The denominator of the fraction is the root of the base number to the numerator power.

... 4^(2/5) = (4^2)^(1/5) = 16^(1/5) = $\sqrt[5]{16}$
