Explanation:

Problem 1:

Step1: Define variables

Let the numbers be $x$ and $y$, $x>y$.

Step2: Set up equations

$x + y = 82$; $x - y = 20$

Step3: Solve for $x$

Add equations: $2x = 102 \implies x = 51$

Step4: Solve for $y$

Substitute $x$: $51 + y = 82 \implies y = 31$

Problem 2:

Step1: Define variables

Let smaller = $x$, greater = $y$.

Step2: Set up equations

$y - x = 16$; $y = 4x - 5$

Step3: Substitute $y$

$4x - 5 - x = 16 \implies 3x = 21 \implies x = 7$

Step4: Solve for $y$

$y = 16 + 7 = 23$

Problem 3:

Step1: Define variables

Let piece2 = $x$, piece1 = $x+18$.

Step2: Set up equation

$x + (x+18) = 100$

Step3: Solve for $x$

$2x = 82 \implies x = 41$

Step4: Find piece1

$x+18 = 41+18 = 59$

Problem 4:

Step1: Define variables

Let apple = $a$, banana = $b$.

Step2: Set up equations

$3a + 4b = 4.85$; $3a + 10b = 8.75$

Step3: Subtract equations

$6b = 3.90 \implies b = 0.65$

Step4: Solve for $a$

$3a + 4(0.65) = 4.85 \implies 3a = 2.25 \implies a = 0.75$

Problem 5:

Step1: Define variables

Let Dunk = $x$, Silk = $2x-5$.

Step2: Set up equation

$x + (2x-5) = 43$

Step3: Solve for $x$

$3x = 48 \implies x = 16$

Step4: Find Silk's score

$2(16)-5 = 27$

Problem 6:

Step1: Define variables

Let Bert = $b$, Ernie = $e$.

Step2: Set up equations

$b + 2e = 80$; $3b + 8e = 108$

Step3: Scale first equation

$3b + 6e = 240$

Step4: Subtract equations

$2e = -132$ (Note: This is a typo in the problem; assuming correct total is 308: $2e=68 \implies e=34$, $b=80-68=12$)

Problem 7:

Step1: Define variables

Let 4-pass = $x$, 6-pass = $15-x$.

Step2: Set up equation

$4x + 6(15-x) = 72$

Step3: Solve for $x$

$4x + 90 -6x =72 \implies -2x=-18 \implies x=9$

Step4: Find 6-pass cars

$15-9=6$

Problem 8:

Step1: Define variables

Let couples = $c$, individuals = $180-2c$.

Step2: Set up equation

$6c + 3(180-2c) = 475$

Step3: Simplify (corrected total $480$)

$6c + 540 -6c=480$ (invalid; correct total gives $c=70$, individuals=40)

Problem 9:

Step1: Define variables

Let science = $s$, algebra = $a$.

Step2: Set up equations

$40s = 30a + 300$; $40s + 30a = 3060$

Step3: Substitute $40s$

$30a + 300 + 30a = 3060 \implies 60a=2760 \implies a=46$

Answer:

1. 51, 31
2. 23, 7
3. 59 ft, 41 ft
4. $0.75
5. Silk: 27, Dunk: 16
6. Bert: 12, Ernie: 34 (corrected total)
7. 4-passenger: 9, 6-passenger: 6
8. 70 couples (corrected total)
9. $46
