The exact number is 8,784 toffees but if you want me to estimate to the nearest tens then it would be 8,780
3x-4=-31
+4 +4
3x=27
X=9
Hope this helps
<h3>Answer: x < -2, choice B</h3>
===========================================
Work Shown:
10x + 18 < -2
10x + 18-18 < -2-18 ... subtract 18 from both sides
10x < -20
10x/10 < -20/10 ... divide both sides by 10
x < -2
These cannot be solved.- 3 unknowns require 3 equations
