Answer:

x = 22

Step by step solution:

5x+(3x-18)+x=180

Simplifying

5x + (3x + -18) + x = 180

Reorder the terms:

5x + (-18 + 3x) + x = 180

Remove parenthesis around (-18 + 3x)

5x + -18 + 3x + x = 180

Reorder the terms:

-18 + 5x + 3x + x = 180

Combine like terms: 5x + 3x = 8x

-18 + 8x + x = 180

Combine like terms: 8x + x = 9x

-18 + 9x = 180

Solving

-18 + 9x = 180

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '18' to each side of the equation.

-18 + 18 + 9x = 180 + 18

Combine like terms: -18 + 18 = 0

0 + 9x = 180 + 18

9x = 180 + 18

Combine like terms: 180 + 18 = 198

9x = 198

Divide each side by '9'.

x = 22

If 1 inch is 500 miles, then 4 inches is how many miles?

tiny-mole [99]

Answer:

2,000 miles

Step-by-step explanation:

We are given:

$1 inch=500 miles$

This can be rewritten as:

$\frac{500 miles}{1inch}$

This is representative of a unit rate, as we have a $1$ in the denominator. To calculate the number of miles in $4$ inches, simply multiply the unit rate by $4$ :

$\frac{500 miles}{1inch}*4=$

$\frac{2000 miles}{4 inches}$

This can rewritten as:

$4inches=2000miles$

Therefore, there are 2,000 miles in 4 inches.

We can check our solution by simplifying the fraction $\frac{2000 miles}{4 inches}$ by dividing both $2000$ and $4$ by $4$ to see if we achieve the unit rate:
