The sum of three numbers is 103. The second number is 7 more than the first. The third number is 3 times the second. What are th
leva [86]

Answer: 15,22 and 66

Step-by-step explanation: Call the numbers a,b and c.

Their sum is 103 so a+b+c=103

The second number is 7 more than the first so b=a+7

The third number = 3 times the second so c=3b

Now replace c with 3b in the top equation, so a+b+3b=103, which becomes a+4b=103

Now replace b with a+7, so a+4(a+7)=103. This solves to give a=15

b=a+7 so b=22 and c=3b so c=66

I only need the step by step process I know the answer. emergency someone please answer! Will mark best answer
Leokris [45]

Step-by-step explanation:

1. y=(x-2)²-9

Using Formula (a-b)²=a²-2ab=b²

y=(x²-4x+4)-9

y=x²-4x-5

Using Mid term Break

y=x²-5x+x-5

y=x(x-5)+1 (x-5)

y=(x+1)(x-5)

2. y= -(x-5)²+16

Using the same formula as above

y= -(x²-10x+25)+16

y= -x²+10x-25+16

y= -x²+10x -9

Taking (-) as Common

y= -(x²-10x+9)

y= -(x²-9x-x+9)

y= -[x(x-9)-1(x-9)]

y= -(x-1)(x-9)
