Create an expression without parentheses that is equivalent that is equivalent to 4(6x+x)
Svetradugi [14.3K]
This is what the distributive property is all about.
  4(6x +x) = 4*6x +4*x = 24x +4x
Of course, this can be simplified further by combining the terms.
  24x +4x = (24 +4)x = 28x

Equivalent expressions without parentheses are ...
  24x +4x
  28x

Janelle and Swetha are taking a 50 question test. Janelle started after Swetha had already finished 12 questions. Janelle answer
steposvetlana [31]
Begin by finding the two equations like this:
Janelle equation: x=2t.
Swetha equation:y=\frac{5}{4}+12t since y = 12 when the time t = 0. 
In order to find how many time it takes to Janelle in order to catches 
up solve the equation: \frac{5}{4}t+12=2t
Solving the above equation for t we get: t=16
So she catches up after 16 minutes. 
Compute like this: 2\times16=32
They were on question 32 then.
