Hello!
To solve this exercise, let's think a bit and choose the best option for each alternative.
<h2>(a) Karen's desk is about 3...</h2>
Well, a desk with 3mm or 3cm is too small, and with 3km is too big.
In this case, the best option is 3 meters (even though it's big, it's the best option).
<h2>(b) Dan's refrigerator has a mass of 80...</h2>
Usually, a refrigerator is heavy. So the best option is kilograms.
<h2>(c) The bucket holds about 5... of water.</h2>
5ml of water is too little, it fits in a spoon. The correct option is liters.
Answers:

Step-by-step explanation:
problem 1.
1. 6y = 30
2. y = 5
3. 3x + 2(5) = 16
4. 3x+10=16
5. 3x=6
6. x=2
solution: (2,5)
problem 2.
1. x=7
2. 4(2)-2y=18
3. 28-2y=18
4. -2y= -10
5. y=5
solution (7,5)
problem 3
10x=10
x=1
7(1) +y =-2
y=-9
(1,9)
problem 4
0= -6
no solution
problem 5
0=0
Infinite many
