Answer:
The price after the discount but before the tax is $21
Step-by-step explanation:
Here, we are told there is a price off of 40% on an item that costs $35.
What we want to calculate is the value of what the price would be before the tax
We proceed by finding 40% of $35
Mathematically, that would be;
40/100 * 35 = $14
The price of the item before the tax is thus;
35-14 = $21
Answer:
5
Step-by-step explanation:
let the number be a.
5a=25
divide both sides by 5
5a=25
5divide by 5a is a.
5divided by 25 is 5
therefore,a=5.
the number is 5
Answer:
2x + 3y = -10
Step-by-step explanation:
First convert the line into slope intercept form to find the slope of the line.
2x + 3y = 4
3y = 4 - 2x
y = -2/3x + 4/3
The slope of the line is -2/3. Parallel lines have the same slope so the slope for a line through the point (1,-4) will be -2/3. Substitute m = -2/3 and (1,-4) into the point slope of a line.
Now convert the line into standard form by using the distributive property.
225/100
225 ÷ 25 = 9
100 ÷ 25 = 4
So, 225% as a fraction in it's simplest form would be 9/4
If you want 225% as a decimal:
225/100
225 ÷ 100 = 2.25
So, 225% as a decimal in its simplest form would be 2.25
I really hope this helped you! c:
Please, Karla, explain what "C" and "n" represent. Are you talking about combinations (for example, n+2 objects taken n at a time? Or is C some kind of function? I don't quite see the relationship of this problem to 'data management.'
