Answer:
5400
Step-by-step explanation:
Let x represent the cost of a chair and y represent the cost of a table. We can use this to set up a system of equations:
7x=2y
6x+5y=10575
We can solve this system using substitution.
Start by rewriting the first equation in terms of x.
Substitute this into the second equation:
Multiply both sides by 7
Divide both sides by 47
This means...
Divide both sides by 7
One chair costs 450. Now, multiply this number by 12 to find the cost of 12 chairs.
12 chairs cost 5400.
The answer is 11

<h3>The length in standard notation is 0.05 meter</h3>
<em><u>Solution:</u></em>
Given that,
Jeremy measured the length of an ant as 
We have to write the length in standard notation
From given,
Thus the length in standard notation is 0.05 meter
<em><u>Method 2:</u></em>
Use the exponent of 10 to determine how many places to move the decimal point
Since exponent is -2, is negative
Thus, we have to move the decimal point to right 2 places
Thus the length in standard notation is 0.05 meter
