Add: 5 (0.5k - 1) + 2 (0.4 - k). Answer should be in decimal form. (1 point)
5 (0.5k - 1) + 2 (0.4 - k) can be simplified as follows:
5 (0.5k - 1) + 2 (0.4 - k)
= 2.5k - 5 + 0.8 - 2k
Combining like terms:
= 2.5k - 2k - 5 + 0.8
= 0.5k - 4.2
Therefore, the answer is 0.5k - 4.2.
Subtract ¼(2 + 4) - 3 (‡≥ + 1). Use fractions in final form. (1 point)
To solve the expression: ¼(2 + 4) - 3 (‡≥ + 1), we first simplify the terms within parentheses:
2 + 4 = 6
‡≥ + 1 = ‡≥1
Now we substitute these values back into the expression and continue solving:
¼(2 + 4) - 3 (‡≥ + 1)
= ¼(6) - 3(‡≥1)
Next, we simplify the fractions:
¼(6) = 6/4 = 3/2
Substituting this value back into the expression:
3/2 - 3(‡≥1)
Now we distribute the -3 to both terms in the parentheses:
3/2 - 3 ೠ- 3(1)
3/2 - 3 ೠ- 3
Finally, we have:
3/2 - 3 ೠ- 3
Since we don't have specific values for ‡≥, we cannot simplify the expression further and leave it as 3/2 - 3 ‡≥ - 3.
