Answer:
L Pie - $7.50
B Pie - $4.50
Step-by-step explanation:
Let's create equations with the given things:
1. Two lemon meringue pies cost $3 less than four blueberry pies.
2L - $3 = 4B
2. Three lemon meringue pies cost #9 more than three blueberry pies.
3L = $9+3B
3. Let's solve these 2 equations
1. -3(-4B+2L=-3)
2. 2(-3B+3L=9)
3. Adding these 2 equations:
12B-6L = 9 ----(1)
-6B+6L= 18 ----(2)
(1) + (2) => 6B=27
B=$4.50
4. 2L = 4(4.50) - 3
L= $7.50

Answer:
36 crickets per day
Step-by-step explanation:
Calculation for how many crickets do the lizards eat each day
Using this formula
Numbers crickets eaten per day=Crickets per week/Numbers of days in a week
Let plug in the formula
Numbers crickets eaten per day=250 crickets per week/7days
Numbers crickets eaten per day=35.7
Numbers crickets eaten per day=36 crickets per day (Approximately)
Therefore the numbers of crickets that the lizards eat each day is 36 crickets per day
The answer is the option C, which is:
C. √29
The explanation of this exercise is:
To solve this problem you must apply the proccedure shown below:
1- You have that:
W (-2,8,-3) and X(1,4,-1)
2- Therefore, you can calculate the magnitude as below:
|WX|=√[(1-(-2)]²+(4-8)²+[(-1-(-3)]²)
|WX|=√29
