Answer:
50
Step-by-step explanation:
let the number be x
15% of x= 0.15x
0.15x=30
(divide both sides by 0.15)
x= 200
25% of 200 = 25/100 *200
= 50
Answer:
the answer is 5n+8
Step-by-step explanation:
4n+n=5n
6+2=8
Since the four choices have solution, there is no choice that have no solutions. (Correct choice: E)
<h3>What linear equation has no solution?</h3>
Herein we must check each choice to find if a solution exists or not by <em>algebra</em> properties. Now we proceed to check each case:
Choice A
1/(x - 31) = 5
1 = 5 · (x - 31)
1 = 5 · x - 155
5 · x = 156
x = 31.2
Choice B
12 · x - 11 = 0
12 · x = 11
x = 11/12
Choice C
15 - 3 · x = - 8
3 · x = 23
x = 23/3
Choice D
- x + 91 = 0
x = 91
Since the four choices have solution, there is no choice that have no solutions. (Correct choice: E)
<h3>Remark</h3>
The statement presents typing mistakes and is incomplete. Correct form is shown below:
<em>Which equation has no solution?</em>
<em>A. 1/(x- 31) = 5</em>
<em>B. 12 · x - 11 = 0</em>
<em>C. 15 - 3 · x = - 8</em>
<em>D. - x + 91 = 0</em>
<em>E. Neither of all</em>
