Answer:

Step-by-step explanation:

1) 8a - 19 = 5 +3a

8a - 3a -19 = 5

8a - 3a = 5 + 19

5a = 24

a = 24/5

a = 4.8

2) 8 + 4d - 7 = 4 - d

8 - 7 + 4d = 4 - d

1 + 4d = 4 -d

4d + d = 4 - 1

5d = 3

d = 3/5

d = 0.6

3) 12t + (1-7t) = 31

12t + 1 - 7t = 31

12t - 7t = 31 - 1

5t = 30

t = 30/5

t = 6

michelle and rosa are researching the deepest lakes in the united states for a school project. lake tahoe has a depth of 1,644 f

Hatshy [7]

Answer:

Rosa is closer to the correct depth.

Step-by-step explanation:

To show that two measurements are nearly equivalent, we must convert one of the measurements to the other unit.

1 m = 3.281 ft

$\text{Depth } = \text{1644 ft} \times \dfrac{\text{1 m}}{\text{3.281 ft}} = \textbf{501.1 m}$

Neither is correct but Rosa is closer to the correct depth.
