25 out of 65 people are wearing red, if there are 65 people at the party and only 25 are wearing red you would find the percentage by dividing 65 by 25 which equals to 2.6%
i hope this is correct im not great at math but i hope this helps

Answer:
this one is supplementary and x equals 31
Step-by-step explanation:
Remember, complementary angles add up to equal 90 degrees whereas supplementary angles add up to equal 180 degrees.
In this case, since your angles together form a straight line, they're supplementary angles. Now, to solve for x:
(3x + 25) + 2x = 180 (step 1: set the equation equal to 180)
5x + 25 = 180 (step 2: combine like terms)
-25 -25 (step 3: subtrace 25, BS)
5x = 155
5x / 5 = 155 / 5 (step 4: divide by 5, BS to get x by itself)
x = 31
3x + 2y=-10 equation 1
y=-x -4 equation 2
use the substitution method of elimination to get the answer to the question.
*using substitution
substitute equation 2 in one and we get
3x +2(-x-4)=-10
3x- 2x-8=-10
x=-2 and y=-2
Answer:
B
You can solve this problem algebraically by representing each of the unknown values (the dimensions of the playpen or its length and width) with certain variables. Then, you represent the length in the terms of the width, as it is 20 feet longer than the length. What you may do next is substitute all of the parts of the equation that you've composed into the area formula for the rectangle, and then you can solve for the width and then for the length of the playpen, hence finding its dimensions.
