creativ13 [48]

Answer:

The answer is A

Step-by-step explanation:

x+y=18

5x+9y=122

When you solve this system of equations, you get x=10 and y=8. Thus, 5*10, or 50, of the 122 right-handed students are female. Therefore, the probability that a right-handed student selected at random is female is

50/122

which to the nearest thousandth is 0.410.

Literal equations 5y-72=7+5x
joja [24]

Step 1. Add 72 to both sides

5y = 7 + 5x + 72

Step 2. Simplify 7 + 5x + 72 to 5x + 79

5y = 5x + 79

Step 3. Divide both sides by 5

y = 5x + 79/5
