Answer:
Step-by-step explanation:
The expression (2 square root sign 27) - (3 square root sign 32) is 
.
To simplify, simplify inside the radicals by removing perfect square factors.
The expression becomes .
This cannot be simplified anymore because whats under the radical is not the same.
<em>Note:</em>
<em>Your questions sound a little unclear.</em>
<em>But, I am assuming your questions as:</em>
<em>''70% of x is 14 min. Find the value of x''.</em>
<em>So, I will solve assuming this statement which anyways would clear your concept. </em>
Answer:
The value of x = 20.
Step-by-step explanation:
Given
<em>''70% of x is 14 min. Find the value of x''.</em>
Thus,
70% of x = 14
70/100 × x = 14
0.7x = 14
divide both sides by 0.7
0.7x/0.7 = 14/0.7
x = 20
Therefore, we conclude that the value of x = 20.
Answer:
$2.85
Step-by-step explanation:
First, add the bill up ($8.70 + $10.30 = 19). So now you need to find what 15% of $19 is...To find the percentage of something you need to turn it into a decimal, 0. (whatever the percentage number is). So in this case, 19 times 0.15, which is a tip of $2.85.
