Answer:
The number is 450
Step-by-step explanation:
Of means multiply and is means equal
6% * number = 27
Change to decimal form
.06 * number = 27
Divide each side by .06
.06 number/ .06 = 27/.06
number =450
The final answer is x=12
So the ladder will reach 12 feet up
Answer:x=9
Step-by-step explanation:
To find the positive solution for this, then we will say;
Let the number be x
3x<x^2-54
x^2-3x-54<0
Then we are going to factorise
x^2-9x+6x-54=0
(x^2-9x)+(6x-54)=0
x(x-9)+6(x-9)=0
(x+6)(x-9)=0
Therefore, The positive solution for this is: x=9
When you multiply radical expressions you multiply the numbers under the radical symbols.<span><span>3–√</span>×<span>7–√</span>=<span>21<span>−−</span>√</span></span>
When you add radical expression you CANNOT add the numbers under the radical symbols.
<span><span>3–√</span>+<span>7–√</span>≠<span>10<span>−−</span><span>√</span></span></span>
Simple...
you have: 15x+2=17
Isolate the variable (x)-->>>>
15x+2=17
-2 -2
15x=15
x=1
To check it-->>>
15(1)+2=17
17=17
Thus, your answer.
