A bag contains 7 red, 5
orange, and 6
green jellybeans. What is the probability of reaching into the bag and randomly withdrawing 13
jellybeans such that the number of red ones is 6
, the number of orange ones is 3
, and the number of green ones is 4
? Express your answer as a fraction or a decimal number rounded to four decimal places.

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.

the answer is that it is true

so mark-up is 0.4 multiplied by 180 = 72
