To get the percent of increase, we will follow these steps:
1- get the difference between the two numbers:
difference = 1.8 - 1.2 = 0.6
2- divide the difference from step one by the original number (the number before the increase) and then multiply the quotient by 100 to get the percent as follows:
% of increase = (0.6 / 1.2) * 100 = 50%
Based on the above calculations, the percent of increase in the amount of iron is 50%
Answer:
X=9
Step-by-step explanation:
perimeter =2L+2B
6= 2(x-6)+2(x-9)
6= 2x- 12+2x- 18
6= 4x-30
4x=30 + 6
4x=36
divide both sides by 4
x= 9
