What is 15 increased by 60%

Answers

What is 15 increased by 60 percent? Let's work it out!

First, you must know what 60 percent of 15 is.

60 percent of 15
  15 times .60 
equals
9.

So 60% of 15 is 9.


Increased is a word which means added.

So, 15 plus 9 (15+9) is 24.

Final Answer = 24.




Hope I could help!
Ossashi(◔ ͜ʖ◔)









60% of 15 is:
15* (60/100)= 9

15+9= 24

The final answer is 24.

4(x + 3) + 2x = 6(x + 2)5 + 2(3 + 2x) = x + 3(x + 1)

5(x + 3) + x = 4(x + 3) + 3

4 + 6(2 + x) = 2(3x + 8)

which one has no solutions ?

Answers

The second option is your answer. 

5 + 2(3 + 2x) = x + 3(x + 1)
5 + 6 + 4x = x + 3x + 3
11 + 4x = 4x + 3

Subtract 4 from both sides. You are left with an untrue statement:
11 = 3
11 ≠ 3 so therefore your answer is no solution. 
Let’s try to look at each one.

First one:
4(x+3)+2x=6(x+2)
We can multiply.
4x+12+2x=6x+12
By looking at this, you can tell it’s equal due to the fact when you add like terms, they will have to same answer.

Second one:
5+2(3+2x)=x+3(x+1)
Let’s multiply.
5+6+4x=x+3x+1
I can already tell this isn’t equal. One has +11 and the other has +1. To make sure, let’s have x=1
5+2(3+2)=1+3(1+1)
5+2(5)=1+3(2)
5+10=1+6
15=7
7 and 15 are not the same number, so the second one doesn’t have any solutions.

Answer:

Solution set= {(3,-9)}

Step-by-step explanation:

x² +6x-27=0

x² +9x-3x-27=0

x(x+9) -3(x+9)=0

(x-3)(x+9)=0

x-3=0; x+9=0

x=3; x=-9
