An ocean depth finder shows number of feet in the depth of water at a certain place. The difference between D, the actual depth of the water, in the depth finder reading, X, is the absolute value of D minus X and must be less than or equal to 5% of the actual depth. If the depth finder reading is 620 feet, what is the greatest number of feet of the actual depth of the water?

g

step-by-step explanation:

the square root of what number? if you add that, then someone will probably answer the question.

hi there!

the answer to this question is d: 35

step-by-step explanation:

5 to the power of 2 is 25

2 multiplied by 5 is 10

then you add the 2 numbers and you get 35

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
