Answer:
Number of cans of glycol solution needed = 24 cans
Step-by-step explanation:
Total glycol solution needed = 42 gallons
Volume of each can of glycol solution = 1.75 gallon
How many cans will be needed
Number of cans of glycol solution needed = Total glycol solution needed / Volume of each can of glycol solution
= 42 / 1.75
= 24
Number of cans of glycol solution needed = 24 cans
Step-by-step explanation:
-4m -5n = 1 ------------------(1)
-6m +12n = -18--------------(2)
multiplying eq (1) by 3 and (2) by 2
therefore, the new eq obtained is
-12m -15n = 3 --------------(3) subtracting (3) AND
-12m +24n = -36-----------(4) <u>(</u><u>4</u><u>)</u>
(+) (-) (+)
-----------<em>-</em><em>-</em><em>-</em><em>-</em><em>-</em><em>-</em><em>-</em><em>-</em><em>-</em><em>-</em><em>-</em><em>-</em><em>-</em><em>-</em><em>-</em>
<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em>-</em><em>3</em><em>9</em><em>n</em> = 39
n= -1 ------------(5)
subtituting (5) in (1)
therefore,
-4m -5×-1 =1
-4m +5=1
-4m=1-5
-4m=-4
m= 1
hence calue of m is 1 and n is -1
