Answer: 
Step-by-step explanation:
Given , A farmer plowed a rectangular section of land for a new crop.
Dimensions of the section is given by :-
Length by width = 
Since , the area of a rectangle = length x width
Then, the total area in yards of plowed section of land will be:

Hence, the total area in yards of plowed section of land = 
Answer:
Part A)
The number of marbles that Su has at the beginning is 
The number of marbles that Bertha has at the beginning is 
Part B)
The number of marbles that Su has at the end is 
The number of marbles that Bertha has at the end is 
Step-by-step explanation:
Let
x------> number of marbles that Su has at the beginning
y------> number of marbles that Bertha has at the beginning
we know that
----> equation A
----> equation B
substitute equation A in equation B



Find the value of x

Part A) How many marbles did they EACH have at the begining?
The number of marbles that Su has at the beginning is 
The number of marbles that Bertha has at the beginning is 
Part B) How many did they EACH have at the end?

so


therefore
The number of marbles that Su has at the end is 
The number of marbles that Bertha has at the end is 
Answer:the number of hot dogs is 10
Step-by-step explanation:
Let x represent the number of hamburgers.
Let y represent the number of hot dogs.
The ratio of hamburgers to hot dogs is 6 to 5. This means that the ratio of x to y is 6/5
x/y = 6/5
5x = 6y
x = 6y/5
Three times the number of hot dogs is 6 more than twice the number of hamburgers. This means that
3y = 2x + 6 - - - - - - - - -1
Substituting x = 6y/5 into equation 1, it becomes
3y = 2(6y/5) + 6
3y = 12y/5 + 6
Multiplying both sides of the equation by 5, it becomes
15y = 12y + 30
15y - 12y = 30
3y = 30
y = 30/3 = 10
x = 6y/5 = 6×10/5
x = 60/5 = 12
