Here’s how it’s done: you count the total number of m&ms to start.
then, you count the number of each color of m&ms. i’m just making up numbers right now but say there are 50 m&ms total and 10 of them are blue. you would put the number of blue m&ms over the total number of m&ms. this would make the probability you pull a blue m&m 10/50. you would then simplify the answer to 1/5. that would be what u put in the box. remember, i just made up those numbers so that’s not the real answer but hopefully u get the point haha. if ur still confused ask me
High school math tip: learn how to apply the ratios 1:1:√2 for the 45/45/90 right triangle and 1:√3:2 for the 30/60/90 triangle; these two triangles probably constitute 90% of the examples and problems you'll see.
He we have half a square, the 45/45/90 isosceles right triangle, sides in ratio 1:1:√2. We write that ratio for our sides and solve.
1:1:√2 = (3/2)√2 : y : x
Ratios are pretty much like fractions, and we can make fraction equations out of corresponding pairs:
1/1 = ( (3/2)√2 ) / y
y = (3/2)√2
1 /√2 = (3/2)√2 / x
x = (3/2)√2 × √2 = (3/2)(2) = 3
Answer: y = (3/2)√2, x = 3
It's not too hard to get fast at these and just say y=(3/2)√2 because it's an isosceles triangle and x = y×√2 = 3 for the hypotenise.
Answer:
12
Step-by-step explanation:

divide both sides by negative 2

square both sides
6x+3=81
6x=78
x=12
Y=6, X=72
Y=?,X=8
12Y=X
12Y/9=X/9
4/3Y=8
Y=8*3/4
Y=6
