Step-by-step explanation:
Answer:
r > -69
Step-by-step explanation:
13 - r < 82
subtract 13 from both sides
13 - r - 13 < 82 - 13
- r < 69
to flip the inequality sign, multiply both side by -1 to make r positive:
- r (-1) < 69 (-1)
r > -69
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! :)
$39 per gallon
$4,368 = cost of total
Divide ⇒ 4368 : 39
