How tall is the flag pole (please give explanation too)

Tpy6a [65]

Answer:

22 3/4 ft

Step-by-step explanation:

The diagram seems to show a 6 1/2 ft person casting a 9 ft shadow at the same time a flagpole is casting a 31 1/2 ft shadow. You want the height of the flagpole.

<h3>Proportion</h3>

Shadow lengths are presumed proportional to the height of the object making them. This means ...

h/(31 1/2) = (6 1/2)/9 . . . . . all lengths in feet

Multiplying by 31 1/2, we get ...

h = (31 1/2)(6 1/2)/9 = (819/4)/9 = 91/4

h = 22 3/4 . . . . ft

The flagpole is 22 3/4 feet tall.

The difference of six times a number and 7 is -49

gtnhenbr [62]

Greetings!

"<span>The difference of six times a number and 7 is -49"...

In number and variables, this would be:
</span> $6x-7=-49
$
<span>
Add 7 to both sides.
</span> $(6x-7)+7=(-49)+7$
<span>Simplify.
</span> $6x=-42$
Divide both sides by 6.
$(6x)/6=(-42)/6$
Simplify.
$x=-7$

Hope this helps.
