For which equation is x=-1/3 not a solution
a. 7+9x=4
b. 6x-5=7
c. 18+9/x=-9
d. 12x+8=4

Using the figure below, select the two pairs of alternate interior angles. a: point 1 and point 4 b : point 2 and point 3 c: point 6 and point 6d: point 5 and point 7

If x varies directly as y, and x = 7.5 when y = 10, find x when y = 4

Pls what is the decimal equivalent of 5 over 9? select one: a. 0 point 5 bar over top of 5 b. 0 point 6 bar over top of 6 c. 0 point 8 bar over top of 8 d. 0 point 9 bar over top of 9
