Let's rewrite the expression as
So, if 
, you may divide both sides by 
, the equation becomes 
, and the only solution is 
, which means that this is not an identity (an indentity is tautologically true, no matter the value of x).
If instead 
, you are multiplying both sides by zero, so the equation becomes
So, it doesn't matter which value for x you choose, because you will always end up with 
, which is obviously always true.
Answer:
182 feets
Step-by-step explanation:
Given :
Feets dug on Monday 110 feets
Feets dug on Tuesday = 72 feets
Total number fo feets below the ground :
Feets dug on Monday + Feets dug on Tuesday
110 feets + 72 feets = 182 feets
Total feets below the ground is 182 feets
149-18% 149-26.82=122.18
149-122.18=$26.82
18% off of $149=$26.82
Answer:
100 ft long and 100 ft wide
Step-by-step explanation:
The building area is (40 ft)(20 ft) = 800 ft², so the area of the entire plot is ...
9200 ft² +800 ft² = 10000 ft² = (100 ft)²
The plot is square, so its side length is 100 ft.
X is a number
x is doubled
then 5 is subtracted means
2 times x-5
2x-5
result is 37
2x-5=37
solve
add 5 to both sides
2x+5-5=37-5
2x+0=42
2x=42
divide both sides by 2
2/2x=42/2
1x=21
x=21
the number si 21
