Hey!

Solution:
The ratio is FEMALES to MALES.
So its 18/16, 18:16, or 18 to 16.
~Now we need to simplify.
18:16 → 18/2:16/2 → 9:8
*Note* When you have a ratio you need to know which comes first. If you put males to females that incorrect. It has to be correct according to the question.

Answer:
<h2>
the first ordered pair is (-2, -2)</h2><h2>
the second ordered pair is (4,0)</h2>
Step-by-step explanation:
to find the missing values, plug in the given values into the equation:
x-3y=4
the first ordered pair:
we are given a y-value (-2), so lets plug it into the equation:
x-3*(-2)=4
now solve for the missing value:
x+6=4
x=4-6
x=-2
now plug in both x and y and check if the equation is true:
(-2)-3*(-2)=4
-2+6=4
6-2=4
4=4
the first ordered pair is (-2, -2)
the second ordered pair:
we are given a x-value (4), so lets plug it into the equation:
(4)-3y=4
now solve for the missing value:
-3y=4-4
-3y=0
y=0/-3
y=0
now plug in both x and y and check if the equation is true:
(4)-3*(0)=4
4-0=4
4=4
the second ordered pair is (4,0)
Answer:
C. 20
Step-by-step explanation:
We have to isolate x.
6(x - 8) = 72
Distribute 6.
6x - 48 = 72
Add 48 to both sides.
6x = 120
Divide both sides by 6.
x = 20
