4 x -5 = -20 then 12 + -20 = -8
1) 2x + 3 = 2x + 3
This works because if you solve it, you will get either x = x or 3 = 3 which are always true, so x, can have an infinite number of solutions
2) 3(x + 4) = 3x + 11
This has no solution because if you solve it, you're gonna get 12 = 11 and that is NEVER true. Whatever x is, 11 cannot equal 12!
Answer:
median because there is an outlier
Step-by-step explanatio
Problem 1
1 ft = 12 inches
2 ft = 24 inches (multiply both sides by 2)
Multiply by 1/3 to get (1/3)*24 = 24/3 = 8
<h3>Answer: 8 inches</h3>
========================================
Problem 2
1 yard = 3 feet
3 yards = 9 feet (multiply both sides by 3)
1 ft = 12 inches
9 ft = 108 inches (multiply both sides by 9)
so overall, 3 yards = 108 inches
Multiply this by 1/6
(1/6)*(108 inches) = 108/6 = 18 inches
<h3>Answer: 18 inches</h3>
note: 18 inches = 12 inches + 6 inches = 1 ft, 6 inches = 1.5 ft
