Answer:
-1/3
Step-by-step explanation:
The product of 10 and a number is 3 less than the number.
Ok, lets call this number x.
10x = x-3 is how to algebraically write this out.
now, lets subtract x from both sides
9x = -3
Divide by 9
x = -1/3
9 = 3^2
Since 3 squared equals 9, that is how 9 as a power of the base 3 should be written.
2nd one, hope this helps sorry if i am wrong
Can you restate it or rewrite it? It doesn't have enough for me to answer this.

Step-by-step explanation:
l = 3w-16
l-3w = -16
l+w = 96
-4w = -112
w = 28 in
l = 96-28 = 68in
