Answer:

b = 112°

Step-by-step explanation:

The two angles from a straight line. so, they add to 180° .

b + 68° = 180°

subtract 68° from each side

b + 68° - 68° = 180° - 68°

b = 112°

If a train travels at 80 mph for 12 min, what is the distance traveled?

AnnyKZ [126]

Answer:

<h2>ANSWER→ </h2>

16 miles
12 minutes is 1 /5 of a hour
80 ÷ 5 is 16
or 80x 1.466 =117.28 ft per second
12 minutes x 60 seconds is 720
117.28× 720= 84,441.6
84441.6÷ 5280= 15.992 miles.

Work out the value of a and b in the identity.<br> 3ax + 6 - 4(x + b)= 11x + 14

Levart [38]

Answer:

a=5, b=-2

Step-by-step explanation:

If you simplify the equation, you get:

3ax +6 -4x -4b - 11x - 14 = 0 =>

3ax - 15x -4b -8 = 0

group together x's and constants:

(3a-15)x -8 -4b = 0

To make this 0 for all x, we have to find an a such that 3a-15 = 0 and b such that -8-4b = 0. this leads to a=5, b=-2
