Answer:
9 + 10 +x= 21
x=21-19
x=2
add 2 in left hand side to get 21
A change from 45 to 90 represents a positive change (increase) of 100%
Use the formula found below on this webpage to find the percent change by replacing the given values:
Percent change = New - Old|Old| × 100%
Percent change = 90 - 45|45| × 100% =
4545 × 100 = 100% (increase)
Where: 45 is the old value and 90 is the new value. In this case we have a positive change (increase) of 100 percent because the new value is greater than the old value.
