Answer:
98 - 84 = 14(this is the change) now we convert this to a percent
14/1 x 100/100 = 14%
All angles in a triangle add up to 180 so 180 - 60 = 120 then 180 - 155 = 25 then 25+65 = 90 that is the remaining angle but finally 180 - 90 = 90 is the missing angle
If i mean .913 then .91 but if u wrote it correctly then 900
Think: "isolate x." Also, remember that when you mult. or div. terms in an inequality by a neg. # you must reverse the direction of the inequality symbol.
−4x−8>−20 becomes <span>4x + 8<20</span> after dividing the original by -1 and then reversing the direction of the inequality symbol.
Now isolate x, first by subtract 8 from both sides and then dividing the result by 4:
4x + 8 < 20
- 8 < -8
----------------------
4x < 12
Divide both sides by 4: x < 3 (answer)
