Add 5(0.5K - 1) + 2 (0.4 - K) answer should be in decimal form
To simplify the expression 5(0.5K - 1) + 2(0.4 - K), we can distribute the coefficients:
5(0.5K - 1) + 2(0.4 - K) = 2(0.4 - K) + 5(0.5K - 1)
Now, let's distribute the coefficients:
= 2(0.4) - 2K + 5(0.5K) - 5(1)
Simplifying further:
= 0.8 - 2K + 2.5K - 5
Combining like terms:
= -2K + 2.5K + 0.8 - 5
= 0.5K - 4.2
Thus, the simplified expression is 0.5K - 4.2.
To solve the given expression, we will apply the distributive property and combine like terms:
5(0.5K - 1) + 2(0.4 - K)
First step: Simplify the expressions within parentheses.
0.5K - 1 = 0.5K - 1 * 1 = 0.5K - 1
0.4 - K = 0.4 - 1K
Next step: Apply the distributive property.
5 * (0.5K - 1) + 2 * (0.4 - K) = 2.5K - 5 + 0.8 - 2K
Now, combine the like terms.
(2.5K - 2K) + (-5 + 0.8) = 0.5K - 4.2
Therefore, the answer in decimal form is 0.5K - 4.2.
To simplify the given expression, 5(0.5K - 1) + 2 (0.4 - K), we need to distribute the coefficients to the terms inside the parentheses and then combine like terms.
First, distribute 5 to the terms inside the first set of parentheses:
5 * 0.5K = 2.5K
5 * -1 = -5
The expression becomes:
2.5K - 5 + 2(0.4 - K)
Next, distribute 2 to the terms inside the second set of parentheses:
2 * 0.4 = 0.8
2 * -K = -2K
The expression becomes:
2.5K - 5 + 0.8 - 2K
Now, let's combine like terms. The terms with 'K' can be combined:
2.5K - 2K = 0.5K
The expression becomes:
0.5K - 5 + 0.8
Finally, let's combine the constant terms:
-5 + 0.8 = -4.2
The simplified expression is:
0.5K - 4.2
