Ratio of cheese to pepperoni...
45 cheese....20 pepperoni.....45/20 reduces to 9/4 or 9:4
little tip ** be careful of the wording of problems such as these.....because if it asked for the ratio of pepperoni to cheese, it would have been 4:9
Step-by-step explanation:
<1 and <2 are adjacent, Supplementary and linear pair angles
Im assuming you mean 2x^2-3x-9=0 ?
If so, you have to factorise the equation
(2x-3) (x+3) = 0
2x - 3 = 0
2x = 3
x = 1.5
x + 3 = 0
x = -3
x is either 1.5 or -3
They are right except for 12. i think it is C but i could be wrong.
