Answer:

30 + 5<em>d</em> ≥ 120

Step-by-step explanation:

One ticket costs $120 and she already has $30 saved up so the money she makes by dogwalking added to the $30 has to be equal to or greater than 120

  1. 30 for the <u>amount she saved up</u>
  2. 5<em>d</em> where <u><em>d</em></u><u> stands for the number of days she walks dogs </u>
  3. Make this information into one part of the inequality: 30+5<em>d</em>
  4. Then this has to be greater than or equal to 120 so:

<u>30+5</u><em><u>d</u></em><u>≥120</u>

Hope this helps!

slega [8]
Probability = (number of possible successes) / (number of total possibilities).

<u>Number of total possibilities:</u>
Each cube can come up in 6 different ways.
Total number of possibilities = 6 x 6 = 36

<u>Possible successes:</u>
There are  2  different ways to roll a  3 . . .

1 . . . 2
or
2 . . . 1

The probability is  3/36  =  1/12  =  0.0833...  =  (8 and 1/3) percent

Find the sun and express it in simplest form.(-3s-4c+1)+(-3s+3c)
DiKsa [7]

Answer:

-6s-c+1

Step-by-step explanation:

(-3s-4c+1)+(-3s+3c)

We have been given the above expression. To find the sum, we simply collect the like terms and combine them;

(-3s-4c+1)+(-3s+3c) = -3s + -3s -4c + 3c + 1

-3s + -3s -4c + 3c + 1 = -3s - 3s + 3c - 4c + 1

-3s - 3s + 3c - 4c + 1 = -6s - c + 1

Therefore;

(-3s-4c+1)+(-3s+3c) = -6s-c+1
