Answer:
Step-by-step explanation:
p(b)=3/12 = 0.25
p(r)=5/12 = 0.42
p(w)=4/12 = 0.33
p(¬r) = 1-0.42 = 0.58
p(¬w)= 1-p(w) = 0.67
P(not red Inot white)= 0.58/0.67=0.87
Substitute y = 3x - 7 for y in the second equation.
6x - 2(3x - 7) = 12
6x - 6x + 14 = 12
14 = 12? Incorrect. That means no solution.
Answer: this was all i knew how to do, hope it helps:)
x = the granddaughter's age x + 2 = the grandson's age
x + x + 2 ≥ 12 Collect like terms.
2x ≥ 12 Divide both sides by 2.
x ≥ 6 years
x + 2 ≥ 8 years
