solve: 4+8 1/2 : (1/4) to the third power.
solve 11(x+30)=412 (5x18)
please show your work

can someone please help me with this one,

From your information, I do not know how to deal with the first problem. "/" is used online to indicate division.
11(x+30)=412(5x18)
Get rid of parentheses.
11x30 = 4110x36
Combine like terms.
9x = 36
x = 4 
thank you
