1: 9x+3
2: 3m^2+9m-7
3: 3x^2+3y^2+y+4
Those are all of the answers in order! I hope this helps.
2 1/3 + 1 3/4 = 3 10/12
5/6 = 10/12
3 10/12 + 10/12 = 3 20/12 = 4 8/12 = 4 hours 40 minutes
4 hours 5 minutes away from 10:05 would be 6 pm
subtract 35 from that and you get 5:25 pm
Answer:
r = 14
Step-by-step explanation:
9r - 66 = 116 - 4r
+4r +4r
13r - 66 = 116
+66 +66
13r = 182
divide both sides by 13
r = 14
Hope this helps!!!
Let x be the number.
Then;
6x-18=-42 (solve for x now)
6x=-42+18
6x=-24
x=-4
Therefore, this number would be -4.
Hope I helped :)
