Answer:
A. the probability that the sum is 11,given that the first number cube shows a 6
Answer:
Step-by-step explanation:
a+c=62, c=62-a
7a+3.5c=364, using c found above gives you
7a+3.5(62-a)=364 expand left side
7a+217-3.5a=364 group like terms on left side
3.5a+217=364 subtract 217 from both sides
3.5a=147 divide both sides by 3.5
a=42, since c=62-a
c=62-42=20
So 20 children and 42 adult tickets were sold.
Answer:
Answer: d 12x^3 + 3
Step-by-step explanation:
This is a composite function. Just insert g(x) into the x of f(x)
f(x) = 3x
3(4x^2 + 1)
Distribute the three
3(4x^2 + 1)
12x^3 + 3
Answer:
y=17/2 and x=15/8
Step-by-step explanation:
By subsitution, we get 4x+4x+1=16, so 8x=15. Thus, x=15/8. Next, we plug x in to find y. y=4*15/8 +1, or 15/2 +1 = 17/2
