6 numbers per cube

 if one is a 1, then the other one has to be a 2, 4 or 6 to be an odd sum

1+2=3, 1+4=5,1+6=7

 since there are 3 numbers you can get that would be a 3/6 ( reduce to 1/2) probability


so 1/2 probability

Enter the value of n so that the expression (ny + 25.7) + (–45.2y + 13.9) is equivalent to (–33.7y + 39.6).
sergij07 [2.7K]

Answer:

n=11.5

Step-by-step explanation:

we have

(ny+25.7)+(-45.2y+13.9)=(-33.7y+39.6)

Group terms than contain the same variable in the left side of the equation

(ny-45.2y)+(25.7+13.9)=(-33.7y+39.6)

Combine like terms in the left side

(ny-45.2y)+(39.6)=(-33.7y+39.6)

Simplify

ny-45.2y=-33.7y

ny=-33.7y+45.2

ny=11.5y

Simplify the y

n=11.5

expeople1 [14]

Answer:

slope = -4/5

y intercept = -4


Step-by-step explanation:

-5y = 4x+20

divide each side by -5

y = 4x/-5 + 20/-5

y = -4/5 x -4

it is in the form y = mx +b where m is the slope and b is the y intercept

m = -4/5 and b = -4
