Answer:
2.3+r=7.1
move all terms to the left:
2.3+r-(7.1)=0
add all the numbers together, and all the variables
r-4.8=0
move all terms containing r to the left, all other terms to the right
r=4.8 is the answer

Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Large eggs : ≥2 ounces
Mean of 48 large eggs = 2.1 ounces
Mean absolute deviation = 0.08 ounces
0.08 ounces here is the mean absolute deviation of the 48 large eggs weighed, meaning that:
The average of the sum of the absolute differences in each individual egg and the mean value of all eggs weighed is 0.08.
This means that the average difference, variability or deviation in the weight of large eggs weighed is 0.08 ounces around the mean value of all eggs weighed.
Mean Absolute Deviation (MAD) :
Σ|xi - mean| / n
xi = each individual value
n = number of values
2x + 4y = 38......multiply by -5
10x + 3y = 105
-----------------
-10x - 20y = - 190....result of multiplying by -5
10x + 3y = 105
----------------add
-17y = - 85
y = -85/-17
y = 5
2x + 4y = 38
2x + 4(5) = 38
2x + 20 = 38
2x = 38 - 20
2x = 18
x = 18/2
x = 9
solution is : (9,5)
