Add: 5(0.5k−1)+2(0.4−k) . Answer should be in decimal form.
To simplify the given expression, we will distribute the coefficients:
5(0.5k - 1) + 2(0.4 - k)
= 2.5k - 5 + 0.8 - 2k
= (2.5k - 2k) + (0.8 - 5)
= 0.5k - 4.2
So, the simplified expression in decimal form is 0.5k - 4.2.
To add 5(0.5k−1)+2(0.4−k), let's break it down step-by-step:
Step 1: Distribute the 5 and 2 to the terms inside the parentheses:
= 5 * 0.5k - 5 * 1 + 2 * 0.4 - 2 * k
Step 2: Simplify the multiplication:
= 2.5k - 5 + 0.8 - 2k
Step 3: Combine 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 expression 5(0.5k - 1) + 2(0.4 - k) and find the answer in decimal form, we need to distribute the numbers inside the parentheses and combine like terms.
Starting with the first part of the expression, 5(0.5k - 1), we distribute the 5:
5 * 0.5k - 5 * 1 = 2.5k - 5
Now let's move on to the second part of the expression, 2(0.4 - k). We distribute the 2:
2 * 0.4 - 2 * k = 0.8 - 2k
Now, we can combine the simplified expressions:
2.5k - 5 + 0.8 - 2k
Combining like terms, we have:
(2.5k - 2k) - 5 + 0.8
Simplifying further:
0.5k - 5 + 0.8
Combining like terms again:
0.5k - 4.2
So, the simplified expression in decimal form is 0.5k - 4.2
