The task can be expressed in a following equation:
120%*a=80%*b
1.20a=0.80b
1.2a=0.8b
12a=8b
3a=2b
1) in terms of a:
3a=2b
b=3a/2=1.5a
a+b=a+1.5a
=2.5a
2) in terms of b:
3a=2b
a=2/3b
a+b=2/3b+b=

I hope this correct and have a great day
If the sequence f is defined as
then
As you can see above, the difference between two consecutive terms gives us a constant.
So f is actually an arithmetic progression (AP), and it has (– 8) as its common difference:
• If f(1) = 100, then

Answer:
y = -2
Step-by-step explanation:
y - 2 = -4
add 2 to both sides
y - 2 + 2 = -4 + 2
y = -2
This is the answer. I did it and got that. You do distributive and then combine like terms.
