Answer:

The elevation of Death Valley = 31/160 feet

Step-by-step explanation: Since

The lowest elevation in Long Beach, California, is 7 ¾ feet 

Let say L = 7 ¾ feet 

The elevation of Death Valley is about 40 times lower than the elevation of Long Beach

That is D = 1/40 of L

D = 1/40 × 31/4

D = 31/160 feet

The elevation of Death Valley is 31/160 feet

Answer:

x < 15

Step-by-step explanation:

Let's first expand the parentheses on both sides. Remember that when expanding parentheses, the result will be the sum of the products of the "outside number" with each of the "inside number".

On the left, the parenthetical expression is: -6(x + 4). Here, the outside term is -6 and the inside terms are x and 4. So:

-6(x + 4) = -6 * x + (-6) * 4 = -6x - 24

On the right, the parenthetical expression is: -5(x + 6). Here, the outside term is -5 and the inside terms are x and 6. So:

-5(x + 6) = -5 * x + (-5) * 6 = -5x - 30

Now put these back in:

-6(x + 4) + 9 > -5(x + 6)

-6x - 24 + 9 > -5x - 30

-6x - 15 > -5x - 30

x < 15

Thus the answer is x < 15.

Hope this helps!
