Answer:
23, 69 and 123
Step-by-step explanation:
let the first number be x then the second number is 3x ( 3 times the first) and the third number is x + 100 ( 100 more than the first number)
The sum of the three numbers is
x + 3x + x + 100 = 215
5x + 100 = 215 ( subtract 100 from both sides )
5x = 115 ( divide both sides by 5 )
x = 23
The 3 numbers are
x = 23, 3x = 3 × 23 = 69 and x + 100 = 23 + 100 = 123
Hi
2/3 y+y-4=31
Simplify both sides of the equation
2/3 y-4=31
Combine like terms
(2/3 y+y)+(-4)=31
5/3 y-4=31
Add 4 to both sides
5/3 y-4+4=31+4
5/3 y=35
Multiply both sides 3/5
(3/5)*(5/3 y)=(3/5)*35
y=21
I hope that's help !
