68-33 blockers ?????????????????????????????????????????!?!!
Answer:
11 inches
Step-by-step explanation:
Let the level of ground level be g
On first day, amount of snow melted by 3 inches
So, level of ground melted= (g- 3) inches
Next day, amount of snow melted by 8 inches
So, level of ground level melted = (g- 3-8 )inches
Hence, total change in the ground level = ( g- 11) inches
Hence, amount of snow on ground level melted by 11 inches
Hence, the correct answer is 11 inches
Your answer is 48, because 96/2 is 48
Hope this helps

The expressions that represent number of tiles that Devon used on her mosaic:
A. 20 + 2t + 2c
D. 20 + t + t + c + c
<h3>What is an expression?</h3>
An expression refers to a mathematical equation which shows the relationship between two or more numerical quantities or variables.
For the expressions that represent number of tiles that Devon used on her mosaic:
- Let the triangle tiles be t.
- Let the circle tiles be c.
- Two rows of t triangle tiles = t + t = 2t.
- Two rows of c circle tiles = c + c = 2t.
Mathematically, the expression is given by:
Total tiles = 20 + t + t + c + c
Total tiles = 20 + 2t + 2c.
