Answer:
Step-by-step explanation:
5 consecutive multiples of 5....
x , x + 5, x + 10, x + 15, x + 20
the average is 20...
(x + x + 5 x + 10 + x + 15 + x + 20) / 5 = 20
(5x + 50) / 5 = 20
5x + 50 = 20 * 5
5x + 50 = 100
5x = 100 - 50
5x = 50
x = 50/5
x = 10......smallest number
x + 5 = 10 + 5 = 15
x + 10 = 10 + 10 = 20
x + 15 = 10 + 15 = 25
x + 20 = 10 + 20 = 30 <=== largest number
It’s should be the first one
Explanation:
The given <em>expression</em> is not an <em>equation</em>. There is nothing that can be <em>solved</em>.
___
An equation has an equal sign between its left side and its right side. Solving it means finding a value for the variable (or variables) such that the equation is true.
For example, we might have ...
5n +1 = 1
Your familiarity with math facts means you know that ...
0 +1 = 1
In order for the term 5n to have a value of 0, the value of n must be 0 in this equation. The solution to 5n+1 = 1 is <em>n = 0</em>, because 5×0 + 1 = 1 is a true statement.
___
An <em>expression</em> can be evaluated. To do that, put the value you want the variable to be every place you see the variable, then do the arithmetic.
To evaluate 5n+1 for n=6 we put 6 in place of n:
5×6 +1
Doing the arithmetic, we get ...
= 30 +1 = 31
The value of 5n+1 for n=6 is 31.
