can someone please help me??

First, let's work on the left hand side of your inequality, the 2x+10 This means, for instance, to see if it can be simplified at all. Multiply x and 2 Multiply x and 1 The x just gets copied along. The answer is x x 2*x evaluates to 2x 2*x+10 evaluates to 2x+10 So, all-in-all, the left hand side of your inequality can be written as: 2x+10 -------------------------------------------------------------------------------- Now, let's work on the right hand side of your inequality, the 26 The right hand side of your inequality can be written as: 26 -------------------------------------------------------------------------------- So with these (any) simplifications, the inequality we'll set out to solve is: 2x+10 › 26 Move the 10 to the right hand side by subtracting 10 from both sides, like this: From the left hand side: 10 - 10 = 0 The answer is 2x From the right hand side: 26 - 10 = 16 The answer is 16 Now, the inequality reads: 2x › 16 To isolate the x, we have to divide both sides of the inequality by the other "stuff" (variables or coefficients) around the x on the left side of the inequality. -------------------------------------------------------------------------------- The last step is to divide both sides of the inequality by 2 like this: To divide x by 1 The x just gets copied along in the numerator. The answer is x 2x ÷ 2 = x 16 ÷ 2 = 8
So we would en up with x >8 and that leaves us with C and D
I think D would be the answer?
Yes, -18 is too far off form 8 so D is correct.
