Answer:
Step-by-step explanation:
Simplifying
2x + 4y = 13
Solving
2x + 4y = 13
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4y' to each side of the equation.
2x + 4y + -4y = 13 + -4y
Combine like terms: 4y + -4y = 0
2x + 0 = 13 + -4y
2x = 13 + -4y
Divide each side by '2'.
x = 6.5 + -2y
Simplifying
x = 6.5 + -2y

Answer:
67,500 men
Step-by-step explanation:
Percent of children = 20% (.2)
30,000 x 5 = 150,000 (Total pop.)
150,000-30,000 = 120,000 (Pop. minus children)
.35 (Percent of women) x 150,000 =52,500
120,000-52,500 = 67,500
You have to find the least common variable, and that would be 10. multiply 2/10 by 10 to get 20/100. 4/100+20/100=24/100. it's C
The answer is 26 because if you round 12.5 it would be 13 and of you would round 1.75 it would be 2. After you do this you would multiply the 2 numbers and get 26 which is your answer.
