IfA = -3n +2 andB = 5n -7, what is the value of A-B, in simplest form?

We substitute the expressions for and to get

Distribute the negative sign to get

Sum like terms:

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500

18a
