To solve the equation 54/x = 9, we can set up a proportion:
54/x = 9
To simplify this equation, we can cross-multiply:
9 * x = 54
This can be further simplified:
9x = 54
To solve for x, we divide both sides of the equation by 9:
x = 54/9
x = 6
Therefore, the number from the set {6, 7, 8} that makes the equation true is 6.
Use substitution to determine which number from the set {6, 7, 8} makes the equation 54÷x=9 true.(1 point)

Based on the given information, the closed circle labeled as A is plotted at the tick mark between 1 and 2 on the number line. This indicates that the value of A is between 1 and 2 but not inclusive, which can be represented as A > 1 and A < 2.
Out of the given options, the equation that satisfies this condition is:
2x = 52
If we solve this equation for x, we get:
x = 52/2 = 26
So, the solution A is x = 26.

Based on the given information, the equation -4 + x = -2 can be rewritten as x = -2 + 4.
This equation indicates that the value of x is 2 units greater than -2. Since the closed circles are plotted at -2 and 2 on the number line, the solution to the equation -4 + x = -2 is x = 2.
