The expression is

t + 11 -14

Let x be positive chips and y be negative chips

xxxxx xxxxx x

yyyyy yyyyy yyyy

The result is -3

t-3

**Step by step explanation**

<u>**let x be the number of minutes and y be the total charges per month**</u>

** **<em>A. Melissa's cell phone plan charges two cents a minute plus a $10 monthly fee. </em>

**<em>y=0.02x+10</em>**

<em> </em>

<em>B. Sandra's cell phone plan charges seven cents a minute. </em>

**<em>y=0.07x</em>**

<em />

<em>C. Holly's cell phone plan charges five cents per minute. She also receives a $5 discount each month.</em>

**<em>y=0.05x-5</em>**

<em />

<em> D. Alicia's cell phone plan charges six cents per minute plus a $5 monthly fee.</em>

**<em>y=0.06x+5</em>**

**Step-by-step explanation:**

Area of trapezium = 1/2(a+b)h

= 1/2(10+24)12

= 1/2×34×12

= 204 square units

**Answer:**

x = 15/8 or 1 7/8

**Step-by-step explanation:**

eliminate denominators by multiplying everything by 15 to get:

15(4/5x) - 15(1/3x) = 15(x) - 15(1)

12x - 5x = 15x - 15

7x = 15x - 15

subtract 15x from each side to get:

-8x = -15

divide each side by -8 to get:

x = 15/8 or 1 7/8
