To make the equation easier so that you don't have to use fractions.
The angles of a triangle always equal 180.
You do 180 - 80 - 45. X = 45.
-4 > -5, -4 is > or equal to 5
Answer: Equation : t - 75 = 325 , Solution: t=400, 400 degree F
t= original temperature
Step-by-step explanation:
Answer:
a.) 20 kilometers
b.)1.67 hours
Step-by-step explanation:
a.) formula= speed =distance/time
Speed= 10km/hr
Distance=unknown
Time=2hrs
Therefore from formula, distance=speed x time
10 x 2
20 kilometers
b.) If average speed is increased by 2km/hr then
total speed= 2+10=12km/hr
Distance remains constant therefore distance= 20km
Therefore time =distance/speed
20/12
= 1.67 hours
