Hello and Good Morning/Afternoon:

Let's take this problem step-by-step:

Let's consider the information given:

rental price: $30 + $0.30/mile
total bill for Ken: $55.20

Let's setup an equation for the cost

set 'x' as number of miles traveled

$\hookrightarrow Cost = 30 + 0.3x$

set that equal to the total cost or bill and solve

$30 + 0.3x = 55.2\\0.3x = 25.2\\x=84$

Ken must have traveled 84 miles

Answer: 84 miles

Hope that helps!

Two angles of a triangle measure 15° and 85°. What is the measure for the third angle

andrezito [222]

Answer: 80°

Step-by-step explanation:

The sum of the angles in a triangle is 180°. Since the two angles of a triangle measure 15° and 85°.

The measure for the third angle will be:

= 180° - (15° + 85°)

= 180° - 100°

= 80°

The third angle is 80°
