Step-by-step explanation:
Given that:
Distance south = 5y miles
East = (2y + 10) miles
Final = (4y + 8) miles
Total cycle in terms of y
Take the sum of the distances :
5y + 2y + 10 + 4y + 8
11y + 20

Step-by-step explanation:
A) 2L + 2W = 192
B) 3L = 5W
Multiplying B) by -2/3
B) -2L +3 (1/3)W = 0 then adding this to A)
A) 2L + 2W = 192
5 (1/3) W = 192
W = 36
L = 60
Area of the lawn = 36 * 60 =

Answer:
2x+1
Step-by-step explanation:
(4-2x), (-7-3x),(11x+6)
Add the three expressions
(4-2x)+ (-7-3x)+(11x+6)
Combine like terms
-2x-3x+11x+4-7+6
6x+3
Divide by the number of expressions which was 3
(6x+3)/3
2x+1
The average is 2x+1
1. Add 3.3 to both sides to cancel the -3.3 out from the side of X
2. Add 3.3 to -0.5 which equals 2.8
Answer: x=2.8
