(1 point)
x = 6
x = 8
x = 27
x = 72

Answer 1

Question 1: Open (there is an equal sign, but no values are provided to determine if it is true or false)
Question 2: False (4x - 3 does not equal 19)
Question 3: -5 (substitute values into the equation to solve for x)
Question 4: 20.5 in (divide 42 in by 2.4 to find the width)
Question 5: x = 6 (24 divided by 4 is equal to 6)
