Answer:
25%
Step-by-step explanation:
Say we start from the beginning with $40. If the pants are discounted but we don't know the percent discount, then we need a variable, x:
40 - x% * 40 = 30
The total is 40. When we take a discount off of 40, we are taking a percent of 40 and subtracting that from 40. From the problem, this should be 30. Thus, the equation above.
Add x%*40 to both sides and subtract 30 from both sides:
x%*40 = 10
Divide by 40:
x% = 1/4 = 0.25
Multiply each side by 100:
x = 25
The answer is 25%.
Just multiply !!
so 1 inch = 5 miles
3.5 inch must be 3.5×5 = 17.5 miles
so the answer is 17.5 miles !!
First you have to subtract 2250015 by 1650650 and the answer is 599365
The you add 2250015 to 1650650 and the answer is 3900665 so you divide
599365 by 3900665 and multiply by 100 and the final result is 517.325002
And to the nearest ten is 517.3 because 2 is below five to round up
Final answer— 517.3
Hope this helps
