Let t and p represent the numbers of turtles and pelicans, respectively.
... 2p + 4t = 114 . . . . . . . the number of legs is 114
... p + t = 34 . . . . . . . . . the number of animals is 34
Divide the first equation by 2 and subtract the second.
... (2p +4t)/2 - (p +t) = (114)/2 - 34
... t = 23 . . . . . . . . . . . . . . . . . . . . . . simplify
Then p = 34 - t = 11
There are 11 pelicans and 23 turtles.
_____
You can get to the same answer by considering the number of legs you would have if all the animals were pelicans. That would be 34*2 = 68. The is 46 fewer legs than there actually are. Each turtle that replaces one of those 34 pelicans adds 2 legs to the total, so to add 46 legs, we must replace 46/2 = 23 pelicans with turtles. That is, there are 23 turtles and 11 pelicans.

Step-by-step explanation:
The probability of an event happening is a number from 0 to 1. A probability of 1 means the event will definitely happen. A probability of 0 means there is no way the event will happen. There is no probability of 50.
7/3 + 3/4
28/12 + 9/12+ 37/12= 3 1/12
FInal answer is 3 1/12
The decimal 0.75 is equivalent to 3/4
Answer:
the number of pounds of cashews Wayne needs, if he plans to use p pounds of almonds
Step-by-step explanation:
Ration of Almonds:cashows = 1:2
Almonds/cashows = 1/2
2Almonds = cashows
f() = 2p <--> cashows = 2Almonds
As a result, the function represents the number of pounds of cashews Wayne needs, if he plans to use p pounds of almonds
