<u>Explanation:</u>
Given:
Principal, P = $2,000
Amount, A = $2500
Time, t = 1 year
Rate of Interest, r = ?
We know:

On substituting the value we get:


Therefore, the rate of interest is 25%
Answer:

Step-by-step explanation:
Let Kat reads k pages of the book.
Miguel reads 5 times as many pages of the book as Kat. So,
m = 5k ...(1)
Together they read 54 pages. i.e.
m+k = 54 ...(2)
From equation (1),

Hence, the equation that can be used to find how many pages Kat read is equal to
.
The answer is 21 + 4x.
You find this answer by adding up all the sides.
9+12+4x= 21+4x ... you don't add 4x because it has a variable that we do not know of the value.
Answer:
I believe the equation would be n - 2 = -15.
Step-by-step explanation:
"4 less than a number (n)" is subtraction. You can write it as "n minus 4". "is -15" means this is the difference. This can also be written as "equals -15".
n - 4 = -15

Answer:
The lcm is; 40b^2n^3
Step-by-step explanation:
There are no common factors between the two expressions and as such the lcm will be found by obtaining the product of he two;
8b^2*5n^3 = 40b^2n^3
