First, we should add 1 to both sides to isolate the variable:
3x = 12
Now that x is isolated, we divide by 3:
x = 4
Answer: negative 6
Step-by-step explanation:
Since at the top of the mountain its already 0 and the degrees drop 3 each hour then multiply -3 by 2 hours and there you go.
Just divide 1 5/8 by 1/3. You will get a decimal of something over four, but you can’t have part of a smoothie made in this problem so four smoothies is your answer!
Whoa just a second there.
What is the question ?
Is the question "Find the percent of increase ?"
In that case, the answer is 300% .
Here's why:
The amount of increase is 75.
The amount of increase as a fraction of
the original amount is
75 / 25 = 3.00 .
To change any number to a percent,
move the decimal point 2 places that way ===> .
3.00 = 300% .
______________________________
The question could have been different.
It could have been "What is the amount of the increase ?"
That's 75.
It could have been "How many times larger is 100 than 25 ?"
100 is 4 times as large as 25, and 3 times larger.
It could have been "How many times has 25 been increased ?"
This is a terrible question ... there are a lot of those in schools.
The answer could be "25 was only increased once, by 75."
The answer could be "25 was increased to 4 times its size."
The answer could be "25 was increased by 3 times its size."
