60 minutes per hour
so 1260 x 60 = 75,600 beats per hour
75,600 * 24 = 1,814,400 beats in 24 hours
Answer:
First you need to identify what the known ratio and and the unknown one
Then you need to setup the proportion.
After that cross multiply and then solve
Lastly check your answer by plugging the result into the unknown ratio and you should get your answer.
Sub -2 for x
h(-2)=3(-2)+1
h(-2)=-6+1
h(-2)=-5
1/2x + 42 = 4x
-1/2x -1/2x
------------------------
42 = 3.5x
/3.5 /3.5
------------------------
12 = x
the number is 12
explanation: 42 more than 1/2 of a number can be written as 1/2x + 42
four times a number can be written as 4x.
42 more than 1/2 of a number is equal to 4 times a number. So 1/2x + 42 = 4x.
Hope this helps :)
