Answer:
discount = 9
new price = 36
Step-by-step explanation:
The discount is the price times the discount percent
45 * 20%
Change to decimal form
45*.20
9
The new price is the original price minus the discount
45-9 = 36
Answer:
- Carlton thinks that converting metric units is as easy as moving the <u>decimal point</u>
Step-by-step explanation:
- When you convert the unit, you move decimal point on your answer from the left to the right or from the right to the left the number of places as per relevant prefix.
<u>Example:
</u>
- 1 meter = 1000 millimeters (1.0 m = 1000.0 mm)
- 1 milligram = 0.001 grams ( 1.0 mg = 0.001 g)

The rise is 1 and the run is 7
The question you asked uses the concept of division, something that a bit tricky at first but gets easier as you master it!
So first let’s write and equation for your problem:
Let x = the amount of calories she burns each hour.
So we already know that Vivi was drumming for 3 hours, that she burned 756 calories, and that she burned the same amount of calories each hour.
Since she burned 756 calories in total, we know that the equation will have to equal 756:
= 756
We also know that the answer will be 3(hours) times x(the amount of calories), so now we just plug it into the equation:
3x = 756
To find what ‘x’ equals we have to divide both side by 3:
3x/3 = 756/3
Now all we have to do is simplify and you have your answer!
x = 252
And there you have it, Vivi burned 25 calories per hour!
Hope this helps! :)
