Answer:
28
Step-by-step explanation:
Let's set the ratio as
7x : 9x
If you add all the states that border an ocean and do not, you will get 48 states (because Alaska and Hawaii are not part of the continental US, as they do not touch the "main" part of the country)
So, we can write this equation.
7x + 9x = 48
Simplify.
16x = 48
Divide both sides by 16.
x = 4
Now, find how many states border an ocean. In our ratio, the number of states that border an ocean was 7x. Substitute x = 4 into 7x
7 * x = 7 * 4 = 28
The number of states that border an ocean is 28.

If you're asking how to simplify, then this is how you do it.
when a power meets another power but in brackets, then you have to multiply the powers. ¼ × 4 would be 1. i simplified 81 to 3⁴.
20 % = 225
1% = 225 / 20
100% = 225 * 100 / 20
= 1125 answer

Hey. Let me help you on this one.
Let's break this problem down so it's easier for us to comprehend it.
There are 850 students in the school, and the amount of female students equals to the amount of male students + sixty additional females.
Amount of students in school = 850 students
Male students =

Female students =

Let's form an equation so we can work with what we have.

Subtract 60 from both sides.

Simplify

Divide both sides by 2.

Answer: There are 395 male students, and 455 female students.
