A customer purchased 30 flowers for a bouquet. If the number of carnations is 3 less than twice the number of roses, which system of equations can be used to find the number of roses, r, and the number of carnations, c, in the bouquet? Group of answer choices

c + r = 30 & 2c + r = 3

c + r = 30 & 2c − r = −3

c + r = 30 & c + 2r = 3

c + r = 30 & c − 2r = −3

where is the rest of the

step-by-step explanation:

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680

the answer is 0.3175 hope that you ^w^

also you might actually want to put this picture up if you want people to solve it luckily i remember this question

10 - 8 = -2

  8 - 6 = -2

etc, so -2 is the common difference
