Answer:
x°+2x°+(x-24)°=180°
Step-by-step explanation:
The sum of of the interior angles of all triangles add up to 180°
Adding x°, 2x°, and (x-24)° <em>will</em> equal 180
Therefore, an equation that can be used to solve for the missing angles is: x°+2x°+(x-24)°=180°

Answer:
3.79 miles per hour to the nearest hundredth.
Step-by-step explanation:
There are 3600 seconds in 1 hour.
50 feet in 9 seconds = 50/9 feet per second.
= (50/9) * 3600 feet per hour
= (50/9) * 3600 / 5280 miles per hour.
= 50 * 400 / 5280
= 3.79 miles / hour.
Answer:
6 years and 1 month
Step-by-step explanation:
A= Pe^rt
Since you need to find the double A=2P
2P=e^0.1132t
0.1132t=ln 2
0.1132t=0.693
t= 6.12
