Answer:

$282.67\ mi$ or $282\frac{2}{3}\ mi$

Step-by-step explanation:

step 1

Find the total distance on a map between Smithville to Clarksville

$334+514=848\ in$

step 2

Find the actual distance

The scale on a map is equal to $\frac{12}{4}\frac{in}{mi}$

Applying proportion

$\frac{12}{4}\frac{in}{mi}=\frac{848}{x}\frac{in}{mi}\\ \\x=848*4/12\\ \\x=282.67\ mi$

Convert to mixed number

$282.67\ mi=282\frac{2}{3}\ mi$

What is the solution to 6(2 - x)<-4x + 2?

cupoosta [38]

Answer:

Solving $6(2 - x)$ we get $\mathbf{x>5}$

Step-by-step explanation:

We need to find solution of $6(2 - x)$

Solving the inequality:

$6(2 - x)$

Multiply 6 with terms inside the bracket

$12-6x$

Subtracting 12 on both sides

$12-6x-12$

Adding 4x on both sides

$-6x+4x$

Divide both sides by -2 and the inequality will be reversed i.e < will be changes to >

$\frac{-2x}{-2}>\frac{-10}{-2}\\\mathbf{x>5}$

So, after solving $6(2 - x)$ we get $\mathbf{x>5}$

What is 8 to the second power open parentheses 3x - 2 closed parentheses + 5 = 56. solve for x

Ratling [72]

8² (3x -2) + 5 = 56 I do the exponents first
64 (3x -2) + 5 = 56 I distribute the 64 over the 3x-2
192x - 128 + 5 = 56 I combined liked terms (-128+5)
192x -123 = 56 I add 123 to both side
192x - 123 +123= 56 + 123 Finally I divide both sides by 192
192x = 179
192 192

x = $\frac{179}{192}$
