15% is expressed as 0.15. Then, 80.00 + 0.15 is 80.15, noting that we add the values digit-wise. Revised Answer: 80 plus 15% = 92 = 80 + (0.15 * 80) = 80 + 12 = 92 or 80 * 1.15 = 92

15 + 80/90 = 143/9 = 15.888

3y+2y+4+1=80 5y+5=80 5y=80-5 5y=75 y=15
If you mean: 80 = 3y+2y+4+1 then 80 =5y+5 and so y = 15
80 = 3 y + 2 y + 4 + 1 80 = 5 y + 5 80 - 5 = 5 y 75 = 5 y 15 = y So Y is 15
95 eight 10's (80) three5s (15) 80 plus 15 is 95
70 + 80 + 70 + 30+ 80 + 80+ 80 = 490
16/3 = 80/15 18/5 = 54/15 80 + 54 = 134/15 = 8 and 14/15
Presumably you want to know the value of y. 3y+2y+4+1 = 80 5y+5 = 80 5y = 80-5 5y = 75 y = 15
80 = 3y + 2y + 4 + 1 80 = 5y + 5 80 - 5 = 5y + 5 - 5 75 = 5y 75 / 5 = 5y / 5 15 = y
