joes family has compleated 60% of a road trip. if they have traveld 30 miles, how far is the full road trip?

Tems11 [23]

The full road trip is 50 miles.

Step-by-step explanation:

Given,

Distance traveled by Joe's family = 30 miles

This represents 60% of the total distance to be traveled.

Let,

x be the total distance.

60% of x = 30

$\frac{60}{100}*x=30\\0.6x=30$

Dividing both sides by 0.6

$\frac{0.6x}{0.6}=\frac{30}{0.6}\\x=50\ miles$

The full road trip is 50 miles.

Using linear pairs,

$115+5x=180\\\\5x=65\\\\x=\boxed{13}$

By the exterior angle theorem,

$2y=45+5(13)\\\\2y=45+65\\\\2y=110\\\\y=\boxed{55}$

y = 2x + 1

9 = 2x + 1

9 - 1 = 2x

8 = 2x

8/2 = x
