Answer:
Eu não entendi, porque se for pergunta de matemática, 415-420 dá um numero negativo que seria -5
Step-by-step explanation:
pense em 420 e tire 415 , simples
The solutions of the equation are x = 15 and x = -20
<h3>How to determine the solutions of the equation?</h3>
The equation is given as:
the absolute value quantity two fifths times x plus 1 end quantity minus 7 equals 0
Rewrite the equation properly as:
|2/5x + 1| - 7 = 0
Add 7 to both sides
|2/5x + 1| = 7
Remove the absolute bracket
2/5x + 1 = 7 and 2/5x + 1 = -7
Subtract 1 from both sides
2/5x = 6 and 2/5x = -8
Solve for x
x = 15 and x = -20
Hence, the solutions of the equation are x = 15 and x = -20

Answer: 20/21 gallons
Step-by-step explanation:
From the question given, we are informed that Maleah turned on the water in the kitchen and that for every 1 3/4 minute, 1 2/3 gallons of water went into the sink.
The number of gallons of water that filled the sink per minute will then be calculated as:
= Amount of gallons of water that went into sink / Number of minutes used
= 1 2/3 ÷ 1 3/4
= 5/3 ÷ 7/4
= 5/3 × 4/7
= 20/21
Therefore, 20/21 gallons of water filled the sink per minute
