Answer:
D; x -y = 22
3x + 2y = 246
Step-by-step explanation:
Let us have the bigger number as x and the smaller as y
The difference between the two is 22
Thus, we have it that;
x - y = 22
twice the smaller number; 2(y) added to thrice the larger 3(x) equals 246
3x + 2y = 246
So we have the two equations as;
x -y = 22
3x + 2y = 246
Because the ratio of women to children is 10:1, double the ratio of men to women so the women are both 10:
Men to women becomes 8:10
Now total the 3 ratios: 8 for men, 10, for women and 9 for children:
8 + 10 + 9 = 27
Divide total people by that number:
270/27 = 10
Multiply 10 by each ratio:
Men = 8 * 10 = 80
Women = 10 * 10 = 100
Children = 9 *10 = 90
There is 80 men.

dark chocolate = 9.6 - 7.9 = 1.7 ounces
Answer:
a) 12
b) 13
Step-by-step explanation:
f(x) = x^2 + 3
g(x) = 2x - 1
a) f(g(2)) = ?
g(2) = 2(2) - 1
= 4 - 1
= 3
f(g(2)) = f(3) = 3^2 + 3
= 9 + 3
= 12
b) g(f(2)) = ?
f(2) = 2^2 + 3
= 4 + 3
= 7
g(f(2)) = g(7) = 2(7) - 1
= 14 - 1
= 13
