Answer:
681
Step-by-step explanation:
5x6=30
30x30=900
2x6=12-10=2
900+2=902
5x3=15
15x15=225
2x3=6
6-10=-4
225-4=221
902-221=681
Let x represent the number:
2/3(x)+15=9
2/3(x)= -6
x= -6/(2/3)
x= -6*(3/2)
x= -9
17) m(slope) = -5
18) m = 1/3
19) m = -1/5
20) m = undefined
21) m = 1/4
22) m = -2/3
23) m = -1
24) m = -1
25) m = -2/3
26) m = -5/2
36 is the answer
9y+5=3y+1+6y+4=>
-9y+3y+6y=5-1-4=>
0=0
