D dnbdsjhdjshshdhdjdhdjdjjdjd you gotta give more points if u want sum 1 to actually answer
Model mural::
L*W = 0.3 sq. ft
--------------
Actual mural::
(5L)(5W) = 25*LW = 25*0.3 = 7.5 sq ft.
Formula for speed = distance/ time
S = 7/.9 = 7.77 miles per hour or 8 mph if you round up.
Simplify 2r + 10 + 4r to 6r + 10
Expand it
Simplify 6r + 18 - 4 to 6r + 14
Cancel 6r on both sides
Since 14 = 10 is false, there is NO solution for this equation so no answer.
