1. men to women = 1:2, 1+2 = 3 people total, 3 = denominator, women = 2 = numerator, so 2/3 women
2. plain to milk = 3:2, 5 total, 5 = denominator
a. plain = 3 = numerator, 3/5 plain
b. milk = 2 = numerator, 2/5 milk
3. children to adults = 3:5, total = 8 = denominator
a. children = 3 = numerator, 3/8 children
b. adults = 5 = numerator, 5/8 adults
4. blue to red to black = 5:1:3, total = 9 = denominator
a. red = 1 = numerator, 1/9 red
b. blue = 5 = numerator, 5/9 blue
5. 2/3 female, 3 total monkeys, so 2 female and 1 male, female to male = 2:1
6. 1/2 female, 2 meerkats total, so 1 female and 1 male, female to male = 1:1
W=8
X=4
9w +5x mean just substitute the corresponding values listed above in this equation
9(8)+5(4)
72+20=92
Answer:
A. 2x+5
Step-by-step explanation:
You can solve these by substituting f(x) as the input (or x value) in g(f(x)). This would be putting the 2x in as the "x" in x+5. So 2x+5.
Answer:
Camille did it right.
Step-by-step explanation:
4x-2y=8
Charlize: | Camille:
-2y=8+4x | -2y=8-4x
y=-4-2x | y=-4+2x
The right answer:
4x-2y=8
+2y +2y
4x=8+2y
-8 -8
2y=4x-8
2y/2=4x/2-8/2
y=2x-4 or y=-4+2x
So Camille is right, because she got y=-4+2x.
