Emilia is shopping for fresh produce at a farmers’ market. she bought a watermelon for $5, and she also wants to buy peppers. each pepper is $0.75. let t represent the total cost of the produce and n be the number of peppers bought. determine which variable is independent and which is dependent, and write an equation that models the situation. then, make a table to show the cost for 1 to 5 peppers.

Answer and Step-by-step explanation:

watermelon =  $5

Each pepper = $0.75

t = total cost of the produce

n = number of peppers bought

t depends on n, because we can only know the price if we know how many peppers were bought

t = 5 + 0.75n

+---+------------+------+

| n | 5 + 0.75n  | t    |

+---+------------+------+

| 1 | 5 + 0.75*1 | 5.75 |

+---+------------+------+

| 2 | 5 + 0.75*2 | 6.50 |

+---+------------+------+

| 3 | 5 + 0.75*3 | 7.25 |

+---+------------+------+

| 4 | 5 + 0.75*4 | 8    |

+---+------------+------+

| 5 | 5 + 0.75*5 | 8.75 |

whats the

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
