Lake Profondo has a depth of 84 feet. Lake Segundo is 5/10 as deep. What is the elevation at the bottom of Lake Segundo?
(Remember, the elevation is below sea level. Account for this in your answer.) (1 point)
Lake Segundo is 5/10 * 84 feet = <<5/10*84=42>>42 feet deep.
Since the elevation is below sea level, the elevation at the bottom of Lake Segundo would be -42 feet.
Use the properties of operations and rules for multiplying and dividing signed numbers to solve:

- 197/15
167/75
To solve this expression, we first simplify the numerator:
(-4)(7/5)(-3/2) = (-4 * 7 * -3) / (5 * 2) = 84 / 10 = 42/5
Next, we divide the numerator by the denominator:
(42/5) / (7/15) = (42/5) * (15/7) = (42 * 15) / (5 * 7) = 630/35 = 18
Therefore, (-4)(7/5)(-3/2) / (7/15) = 18.
Use the properties of operations and rules for multiplying and dividing signed numbers to solve:
(- 4)(7/5)(- 3/3) / (7/15)
(1 point)
To solve this expression, we first simplify the numerator:
(-4)(7/5)(-3/3) = (-4 * 7 * -3) / (5 * 3) = 84/15 = 28/5
Next, we divide the numerator by the denominator:
(28/5) / (7/15) = (28/5) * (15/7) = (28 * 15) / (5 * 7) = 420/35 = 12
Therefore, (-4)(7/5)(-3/3) / (7/15) = 12.
