Answer:

Step-by-step explanation:

Move 3k to left hand side and change it's sign
Similarly, move 4.5 to right hand side and change it's sign

Collect like terms

Subtract 4.5 from 18

Divide both sides by 4.5

Calculate

Answer:
0.35 Gallons.
Step-by-step explanation:
Since there is already 9/10 in it, you can only pour 1/10 in now. 1/10th of 3.5 is 0.35.
The percentage change in perimeter is 100%.
The percentage change in area is 300%
<h3>How to find perimeter and area?</h3>
The perimeter of the sandbox = 2l + 2w
where
Therefore,
perimeter = 2(10) + 2(6)
perimeter = 20 + 12 = 32 ft
The area of the sand box = lw
area = 10 × 6 = 60 ft²
If the length and width are doubled,
length = 2(10) = 20 ft
width = 2(6) = 12 ft
hence,
perimeter = 2(20) + 2(12) = 40 + 24 = 64 ft
area = 12 × 20 = 240 ft²
Therefore,
percentage change in perimeter = 64 - 32 / 32 × 100 = 100%
percentage change in area = 240 - 60 / 60 × 100 = 18000 / 60 = 300%
