Answer:
First number=6
Second number=14
Step-by-step explanation:
Let the first number be x
So the second number is x+8
So the sum of the two is
X+x+8=20
2x+8=20
2x=20-8
2x=12
X=12/2
=6
The second number will x+8
So 6+8=14
First number=6
Second number=14
Answer:
I think it is a maximum value.
Answer:
41
Step-by-step explanation:
x+(x+70)+28=180
x+x+70+28=180
2x+70+28=180
2x+98=180
2x=180-98
2x=82
x=82/2
x=41
Answer:
2*10^-1
Step-by-step explanation:
U shud know y
If they are proportional, then y/x should always be the same.
So 9/2= 4.5
We need to find the y value at x=3 to make y/x equal 4.5
4.5 = y/3
y = 4.5*3 = 13.5
