**Answer:**

18 rungs

**Step-by-step explanation:**

Let x = number of rungs

x/2 = middle

Climbed 3

x/2 +3

Down 5

x/2 +3 -5

Climbed 9

x/2 +3 -5+9

Then climbed 2 more

x/2 +3 -5+9 +2

Now is at the top

x/2 +3 -5+9 +2 =x

Combine like terms

x/2 +9 = x

Subtract x/2 from each side

x/2+9-x/2 = x - x/2

9 = x/2

Multiply each side by 2

18 =x

**Answer:**

**Step-by-step explanation:**

use

i=prt

i=interest

p= principal value

r=rate

t=time

now you want to find time then it will be

t= i/pr

put values

t= 3722/(2000*7.6%)

t= 2 years

calculation is in fraction but your question given you annual interest so time will also be 2 years not in months

Look for groups of 2 (a group of two on the inside, makes one on the outside)

**Answer: C**

**Answer:**

Marty’s with a slope of 1/3

**Step-by-step explanation:**

**Step-by-step explanation:**

**Marty**

**y+3=(1/3)*(x+9)**

**y + 3 = (1/3)*x + 3**

**y = (1/3)*x**

**Marty's slope: 1/3**

**Option 3 is correct**

**Marty’s with a slope of 1/3**

**Step-by-step explanation:**

**Using slope intercept form:**

**The equation of line is: ....[1]**

**where,**

**m is the slope and b is the y-intercept.**

**Formula for Slope is given by:**

**....[2]**

**As per the statement:**

**Marty and Ethan both wrote a function, but in different ways.**

**Marty equation is:**

**using distributive property we have;**

**Subtract 3 from both sides we have;**

**On comparing with [1] we have;**

**Slope of Marty = **

**Ethan wrote a function:**

**Consider any two values from the table we have;**

**(0, 10) and (2, 10.4)**

**Substitute these in [2] we have;**

**Slope of Ethan = 0.2**

**Therefore, . Marty’s with a slope of 1/3 function has the larger slope**
