Answer:
-16.02
Step-by-step explanation:
I assume the "......" is a variable replacement. I will use x instead.
0.18 = x - - 18 + - 1.8
Negative + Negative = Positive
0.18 = x + 18 + - 1.8
Positive + Negative = Negative
0.18 = x + 18 - 1.8
Combine like terms
0.18 = x + 16.2
Subtract both sides by 16.2 to isolate the variable x
0.18 - 16.2 = x + 16.2 - 16.2
-16.02 = x + 0
-16.02 = x
Check your work:
Plug in -16.02 into the original equation
0.18 = -16.02 + 18 - 1.8
They should equal each other; let's check to make sure
0.18 = 1.98 - 1.8
0.18 = 0.18
They equal each other so our answer is correct
Answer is 30 is the least common denominator and 330 is the greatest common denominator
The simplified expression are as follows;
6mn³ - mn² + 3mn³ + 15mn² = 9mn³ + 14mn²
a⁴b³ + 8a⁴b³ = 9a⁴b³
<h3>How to simplify an expression?</h3>
A simplified expression is express to its lowest term.
Therefore,
6mn³ - mn² + 3mn³ + 15mn²
combine like terms
6mn³ + 3mn³ - mn² + 15mn²
9mn³ + 14mn²
a⁴b³ + 8a⁴b³ = 9a⁴b³
