1.	Write 5 less than twice the length equals 11 as an algebraic equation.
		A.	5 < 2 + 11	B.	2 - 5 = 11
		C.	- 5 = 11	D.	2 ÷ 5 = 11
		Hint
	2.	Three more than the product of 6 and a number is 51. Write an equation and find the number.
		A.	6n + 3 = 51; 8
		B.	3 + 6n = 51; 15
		C.	3n(6) = 51;
		D.	6 + n + 3 = 51; 42
		Hint
	3.	Find a solution to the equation using guess-check-and-improve. t · (t + 8) = 4,473
		A.	t = 63
		B.	t = 62
		C.	t = 61
		D.	t = 59
		Hint
	4.	Find a solution to the equation using guess-check-and-improve. Give the solution to the nearest tenth. n + 5 = 3(n - 2)
		A.	n = 9
		B.	n = 8.5
		C.	n = 5.5
		D.	n = 2
		Hint
	5.	Which equation would it be easiest to solve using the backtracking method?
		A.		B.	r2 + r = 15
		C.	r · (4 – r) = 32	D.
