-2x - 4 > 10
Multiply both sides by -1 and reverse the inequality symbol.
2x + 4 < -10
Now subtract both sides by 4.
2x + 4 - 4 < -10 - 4
2x < -14
Divide both sides by 2.
2x/2 < -14/2
x < -7
We can see that John paints at a constant rate: therefore, the correct statement that describes this situation is that John likes to paint.
Haha got you, the correct answer is John paints 1 portrait every 4 hours.
What is that??????????????
Jo makes 170 minutes call. There are 150 free ones
170 - 150 = 20
20 minutes are "what Jo has to pay"
Jo sends 182 texts. There are 150 free ones
182 - 150 = 32
32 texts are "what Jo has to pay"
Monthly charge = 16p, 13p for each extra minute, 15p for each extra text.
13(20) = 260p
15(32) = 480p
480p + 260p + 16 = 740p + 16
740p + 16 is your answer (if p = pounds, add 16 to it, i'm not sure what p stands for though. If it is cents, divide 100 from 740 and take out the p, then add total to 16 to get answer.)
hope this helps
