18 /(y + 18) = 4/9 <<<<===== answer.
be careful the number of boys is in a ratio of the number of boys to the total.
Just to make sure I'm right, I solve it.
18 * 9 = 4*(y + 18)
162 = 4y + 72 Subtract 72 from both sides.
90 = 4y Divide by 4
22.5 = y Never mind the 0.5. Does it work
18/22.5 = 0.8
0.8 is the same thing as 4/5
The problem makes no sense in the real world, but it does work out mathematically.
Answer:
Therefore ,the distance, on a coordinate plane, between the points G(2.-3) and D(2, 4) is 
Step-by-step explanation:
Given:
point G( x₁ , y₁) ≡ ( 2 ,-3)
point D( x₂ , y₂) ≡ (2 , 4)
To Find:
Distance between GD=?
Solution:
Distance Formula between two point is given by
Substituting the values we get
Therefore ,the distance, on a coordinate plane, between the points G(2.-3) and D(2, 4) is
The answer would be approximately 9 inches but the real number is 9.42 So B is the answer. I hope this helped ^^
Answer:
in the point slop form y=2x+8
the slope is 2
the y intercept is 8
