Distribute first. 4 times 3x is 12x and 4 times -5 is -20
12x-20+2x=8 now combine your like terms.
14x-20=8 and add 20 to each side
14x=28 divide
x=2
Because all the digits are the same, each digit is worth 10x the one to its right and 1/10 of the one to its left.
This is because we count in base 10. This is also why we can expand this number to become
9*10^6+ 9*10^5+ 9*10^4+ 9*10^3+ 9*10^2+ 9*10^1 +9*10^0.
Hope this helps!
yes is a linear line because linear mean a straight line
The answer is $182 because 30% of $140 (0.3 × $140 = 42). I added $140 and $42 to get $182.
