Answer: check explanation
Step-by-step explanation:
Multiply both sides of equation by x(x+a)
This will get rid of those nasty fractions...cuz who likes them?
Anyways,
Now you should I think get
x(x+a)+a(ax)=a
I am pretty positive that you just distribute and solve.
You may have to factor and have to put everything as an equation set to equal=0
you try it and experiment. Sometimes you just have to try to think algebraically and creatively. Don’t get frustrated just work with it. Good luck!
2/10ths of an hour. You do 12/60 and get 0.2
Slope = (-12 - 43)/(4 +7) = -55/11 = -5
y = mx + b
43 = -5(-7) + b
43=35+b
b = 8
equation
y = -5x + 8
There started with 50 and it doubles so that means:
100 at the end of year 1
200 at the end of year 2
400 at the end of year 3
800 at the end of year 4
Let us assume the common ratio = x
Then from the given question we can write
7x + 2x = 450
9x = 450
x = 450/9
= 50
Then the quantity 450 grams can be divided in the ratio of 7 : 2 by = 7x:2x
= (7 * 50) : (2 * 50)
= 350:100
I hope this is the answer you were looking for and the procedure for finding the answer is also absolutely clear to you.
