Excercise 1:
No, this is not simplified fully. The full answer would be <span>−7dk+14d−21k</span>−7, not <span>14d - 9 - 21k - 7dk + 2. So, it is not equivalent.
</span><span>
Excercise 4:
</span><span>7dk (2 - 3 - 1) - 7
</span>
Just multiply 7dk into (2) (-3) and (-1)
you'd get:
<span><span>−<span>14dk</span></span>+</span>−<span>7 after simplifying it fully.

p = parameter
w = width
w+2.75
p = 2w+2(w+2.75) = <span>4w</span>+<span>5.5 = 30
Answer to the last one:
w = 6.125</span>
Answer:
7x-4 = -28
4y+8 = 4(y + 2)
Step-by-step explanation:
1. Ebony's right eye....opposite of -1.50 = 1.50
2. the rational numbers are : -1.50, 1.50, -1.00, and 0.25....these are all rational because they can be turned into fractions.
3. least to greatest : -1.50, -1.00, 0.25, 1.50
4. not sure how to answer this...negatives are always less then positives....however, with negatives,unlike positives, the larger the number, the smaller it is.
