Answer:
<h3>
97, 485 and 197</h3>
Step-by-step explanation:
x - the first number
One number is 5 times a first number:
5x - "one" number (the second number)
A third number is 100 more than the first number:
x + 100 - the third number
x + 5x + x+100 - the sum of the three numbers
x + 5x + x+100 = 779
-100 -100
7x = 679
÷7 ÷7
x = 97
5x = 5•97 = 485
x+100 = 97 + 100 = 197
Check:
97 + 485 + 197 = 779
1. Add 4 to both sides of the equation
2. Simplify
3. Divide both sides of the equation by 5
4. Simplify
5. x= 5
1 2/3 = 5/3
4 2/5 = 22/5
5/3•22/5= 110/15
= 22/3
When b does not equal 0 it’s a non proportional relationship
y=mx+b
