You’d set up a proportion. I did 25/15=7x-40/18.
Then you would cross multiply to get 15(7x-40)=450
Distribute the 15.
105x-600=450
Add 600 to both sides, so the -600 cancels out.
Then you’re left with 105x=1050
Divide both sides by 105 and you get x=10
Answer
f(x)=9/x , g(x) = x / x + 1 = 9/2
Step-by-step explanation:
Answer: 2.592 x 10^6 seconds
Explanation:
There are 3600s in 1 hr
And 24hrs in 1 day which mean
There are 3600 x 24 = 86400s in 1 day
And one month = 30 days
86400 x 30 = 2, 592, 000s in 1 month
Write in scientific notation:
2, 592, 000 = 2.592 x 10^6
PEMDAS
do parentheses first
4 x 10=40
40 x 10=400
