Answer:
15
Step-by-step explanation:
315 children
a + 21a = 330 {substituted 21a, in for c, into second equation}
22a = 330 {combined like terms}
a = 15 {divided each side by 22}
15 adults attended
c = 21a {first original equation}
c = 21(15) {substituted 15,
S is the answer
Let 3+4+8+9+13+14+18+___ 40 terms=S
Number of possible outcomes = 10
Given:
(0 or 3) = 2 number
(a, e, i, o, or u) = 5 alphabet
Find:
Number of possible outcomes
Computation:
(0 or 3) ; number of possible outcome = 2
(a, e, i, o, or u) ; number of possible outcome = 5
So,
Number of possible outcomes = 2 x 5
0.185
