Answer:
Multiply the width to the length
Step-by-step explanation:
1. Unless you have the total students, it would be D, because we don't know how many total students there are, so we don't know how many students 100% would be.
2. E. There are only 7% of the students who major in a medical area. So say out of 100 students, 7% of that would be 7 people, and 19% would be 19 people, and so on. So therefore, the least people are majoring in a medical field.
x= length, y=width
Both the length and width were increased by 60% so now they are:
1.6x and 1.6y
Then they were both reduced by 25% so now they are 75%(100-25) of their previous size so they are:
0.75(1.6x) and 0.75(1.6y)
Their area would be length * width so it would be:
0.75(1.6x) * 0.75(1.6y)
Simplified this would be:
1.2x * 1.2y
Simplified more it would be :
1.44xy which is also 144% of xy which is a 44% increase of the original area (xy)
So the answer is:
44%
the answer is x= 10.
the steps would go like this.
4 + 3/5 × (15 + 2x) = 25
4 + 9 + 6/5x = 25
13 + 6/5x = 25
65 + 6x = 125
6x = 125 -65
6x = 60
x = 10
hope this helps
