Answer:
x=5
Step-by-step explanation:
12x+40=15x+25
12x=15x-15
12x=15x-15-15x
-3x=-15
-3x=-15 divide both by -3
answer is 5
5 = x
Subtract 12x from each side
12x-12x+40=15x-12x+25
40 = 3x +25
Subtract 25 from each side
40-25 = 3x+25-25
15 =3x
Divide by 3
15/3 =3x/3
I think we need a coordinate grid for that,,
55%=70.4
1%=70.4/55= 1.28
100%=1.28into 100 = 128
