Hi there! :)

<u>Answer:</u>

r ≤ 2.5


Step-by-step explanation:

<u>-2</u>(r - 3) + 7 ≥ 8

Distribute the "-2" to the entire parentheses → -2 × r = <u>-2r</u>  &  -2 × -3 = <u>6</u>

-2r <u>+ 6</u> <u>+ 7</u> ≥ 8

Add the similar terms together → 6 + 7 = <u>13</u>

-2r <u>+ 13</u> ≥ 8

Subtract "13" from each side of the inequality → 8 - 13 = <u>-5</u>

<u>-2</u>r ≥ -5

Divide each side of the inequality by "-2" → -5 ÷ -2 = <u>2.5</u>

<u>r ≤ 2.5</u> ⇒ Whenever you divide an inequality by a negative number, you must flip the inequality sign!!


There you go! I really hope this helped, if there's anything just let me know! :)

Nick randomly selects a digit from the set { 0 , 1 , 2 , . . . , 9 } and a letter from the set { A, B, C, . . ., Z } . Matthew w
Alex787 [66]

Answer: 259/260 or 0.99615 (depending on which answer format your teacher wants)

There are 10 numbers in the set {0, 1, 2, ..., 9}. There are 26 letters in the set {A, B, C, ..., Z}. Multiply those values: 10*26 = 260. So there are 260 ways to pick a number followed by a letter. One example is 7P.

There is only one way Matthew can get the correct answer, and there are 260 - 1 = 259 ways to get the wrong answer. We divide 259 over 260 to get the probability of getting the incorrect answer, which is 259/260.

If you need this fraction in decimal form, then use a calculator to find that 259/260 = 0.99615 approximately
