ANSWER
8x + 3y = 2000
x => The number of adults
y => The number of children
EXPLANATION
Let the number of adults be x.
Let the number of children be y.
Each adult will be charged $8 admission. This would mean that the charges for x adults will be:
8 * x = $8x
Each child will be charged $3 admission. This would mean that the charges for y children will be:
3 * y = $3y
The club wants to earn $2000 from admission charges. This means that adding the total charges for adults and children should yield $2000.
Therefore, we have:
8x + 3y = 2000
The variables are:
x => The number of adults
y => The number of children
Answer:
<h2>110 and 70</h2>
Step-by-step explanation:
Two supplementary angles add up to 180°
Suppose x + y = 180 and y = x - 40
first we substitute y by x - 40 in the equation x + y = 180 ,we get:
x + (x - 40) = 180
then
2x - 40 = 180
then
2x = 180 + 40
= 220
then
x = 220/2
= 110
therefore
y = 110 - 40
= 70
Hey!
--------------------------------------------------
Steps To Solve:
20 + 4x = 28
~Subtract 20 to both sides
20 + 4x - 20 = 28 - 20
~Simplify
4x = 8
~Divide 4 to both sides
4x/4 = 8/4
~Simplify
x = 2

Hence, the answer is
