I believe the answer is True
x and y are the packs of organic and inorganic fertilizer, respectively.
pounds of nitrogen added = 2x + 6y = 120
pounds of potassium added = 3x + 2y = 54
eliminate the y terms. subtract the first equation from 3 times the second equation.
9x + 6y = 162
-2x - 6y = -120
------------------
7x = 42
x = 6
y = 18
<h2>Question:- Area of the given diagram</h2>
<h2>Answer :- </h2>
Divide the diagram as shown in attachment.
Now first calculate the area of the rectangle having side 1 and 12
So area = length ×breadth
Area = 1× 12 = 12 unit²
Now find the Area of the remaining triangle with sides 12,13,5 units
So
Now put the value as -> base= 5 and height= 12
Now add both areas for your answer
Answer:
$211.9
Step-by-step explanation:
77 MARKERS x 0.70 EACH = 53.9
30 RULERS x 1.95 EACH = 58.5
1 projector x 99.95 = 99.95
53.9 + 58.5 + 99.95 = $211.9
