Answer:

29,035.43 meters

Step-by-step explanation:

What we know:

- The elevation of the shore of the Dead Sea is -1,344.99 meters.

- The summit of Mt. Everest is 30,380.42 meters above the Dead Sea.

So, we just add the two values.

30,380.42 + (-1,344.99)

We can rewrite this as 30,380.42 - 1,344.99 since adding a negative is the same as subtracting that number.

And we get 29,035.43 meters as the elevation or height of Mt. Everest.

let alpha be x and beta be y

Step-by-step explanation:

x+y= -b/a

(-1/6)/(-1/3)-(-1/3)

1/2+1/3

Lavita finally got her beautiful painting done it was a total of 1 2/3 meters. She was able to finish 3/8 each week. how many we

Paul [167]

Answer:

4 weeks

Explanation:

Length of Lavita’s painting = $1 \frac{2}{3} m=\frac{5}{3} m$

Length she was able to finish each week= $\frac{3}{8}m$

Now,

If she is able to finish $\frac{3}{8}m$ in 1 week

Then

$\frac{3}{8}m$ = 1 week

1 m = $\frac{8}{3}m$ week

Therefore

$\frac{5}{3} m=\frac{8}{3} \times \frac{5}{3} \text { week }$

= $\frac{40}{9}$ week

=4.44 week

= 4 weeks (approx.)
