(a) Write an equation that could be used to answer the question above. First, choose the appropriate form Then, fill in the blanks with the numbers 3, 27, and 51. Let x represent the number of t-shirts. square x+square =square square x-square =square (b) Solve the equation in part (a) to find the number of t-shirts. x=square

(a) an equation that could be used to answer the question above, we need to choose the appropriate form and fill in the blanks with the numbers 3, 27, and 51. Let x represent the number of t-shirts.<br /><br />The appropriate form for this equation is $\square x+\square =\square $.<br /><br />Filling in the blanks, we get:<br /><br />$3x + 27 = 51$<br /><br />(b) To solve the equation in part (a) and find the number of t-shirts, we need to isolate the variable x.<br /><br />$3x + 27 = 51$<br /><br />Subtracting 27 from both sides:<br /><br />$3x = 24$<br /><br />Dividing both sides by 3:<br /><br />$x = 8$<br /><br />Therefore, the number of t-shirts is 8.
