Which linear equation represents the statement "4 times the number of coins in my pocket plus 5 more is 29"?
4(x + 5) = 29
4x + 29 = 5
4x + 5 = 29
4 + x + 5 = 29
What is the value of $$x$$ in the equation $$\frac{1}{x + 1} = 5$$?
$$\frac{-4}{5}$$
$$\frac{4}{5}$$
$$\frac{5}{4}$$
$$\frac{-5}{4}$$
What is the solution of the equation $$\frac{x-2a}{2} = 0$$?
x = 2a – 2
x = 2a
x = 2a + 2
x = – 2a

{4, 5, 6, 7}
{5, 6, 7, 8}
{1, 2, 3, 4}
{3, 4, 5, 6}
What is the solution set for the inequation x ≤ 4 when the replacement set is {0, 1, 2, 3, 4, 5, 6, 7, 8}?
{2, 3, 4, 5, 6}
{3, 4, 5, 6, 7}
{0, 1, 2, 3, 4}
{5, 6, 7, 8, 9}
What is the solution set for the inequation 2x > x + 8 if x ∈ {7, 8, 9, 10, 11}?
{3, 4, 5}
{6, 7, 8}
{0, 1, 2}
{9, 10, 11}
