I believe the correct answer is true. <span>When solving a system of linear equations, try to algebraically form one equation that has only one variable. In this way, you can solve the value of that variable and eventually solve the other variables. Hope this answers the question. Have a nice day.</span>
Answer:
Step-by-step explanation:
1) $399 = 84% of the original amount
Divide both sides by 84 to get what one percent would be
$4.75 = 1%
Then multiply both sides to get one hundred percent [the original price]
$475 =100%
Use this method to do the second question
$450.50 = 85%
Divide by 85
$5.30 = 1%
Multiply by 100
$530 = original price
Answer:
x= 7
Step-by-step explanation:
