Answer:
448.23
Step-by-step explanation:
Sales tax is addition to the original price
The original price is 100%
First we find 1% of this, which is 415.99 / 100 = 4.1599
Then multiply this by 7.75 = 32.239225
Add this to the original price = 415.99 + 32.239225 = 448.229225
You have to round this to an appropriate number as the question uses two decimal places I think this will suffice = 448.23
Answer:4200-600m=1800
Step-by-step explanation:
4200-600m=1800
Subtract 4200 from 1800
-600m=-3600
Divide both sides by -600
m=6
Answer:
4
Step-by-step explanation:
So we know that RT is 36.
Note that RT is the combined length of RS and ST. Therefore:
Substitute. RT is 36, RS is 6x+1 and ST is x+7:
Combine like terms and add:
Subtract 8 from both sides:
Divide by 7:
So, our answer is 4 :)
