Given M = 2x + 2y where: • the sum of x and y is at least 6.
x is at least 1; and y is at least 2
What is the smallest possible value of M?​

If c(x) = 4x – 2 and d(x) = x2 + 5x, what is (cxd)(x)

Divide the following fractions 3/4 ÷ 2/3 1/2 8/9 9/8 2

Which of these equations, when solved, gives a different value of x than the other three? a9.1 = -0.2x + 10 b10 = 9.1 + 0.2x c10 – 0.2x = 9.1 d9.1 – 10 = 0.2x
