Answer:
She earns $6.50 from the Smiths which is 25 cents more than she earns at the Nelsons.
Step-by-step explanation:
To solve this problem you must find the hourly rate she earns at the Smiths. This will allow you to compare to the hourly rate that is given for the Nelsons. To find the Smiths hourly rate divide $39 by the 6 hours she babysat there. This will have the hourly rate. 39/6=6.5. This means she earns $6.50 an hour for the Smiths. When comparing the rates it is clear that she earned 25 cents more at the Smiths.
Answer:
<em>x = - √10, and x =√10</em>
Step-by-step explanation:
1. Let us add 3 to either side of the equation: x^2 - 3 + 3 = 7 + 3
2. That equation would simplify to: x^2 = 10
3. Now let us take the square root on either side: √x^2 = √10
4. Being square root of x^2, we could say that: | x | = √10
5. And thus 2 answer may be derived from this equation provided absolute value symbol ( | | ): <em>x = - √10, and x =√10</em>
Answer:
Equations::
4c + 8t = 58
2c + 3t = 23
----------------
Modify for elimination:
4c (4c*1) + 8t (8t*1)= 58
4c (2c*2) + 6t (3t*2)= 46
---------------------
Subtract and solve for "t":
2t (8t-6t) = 12
t = $6 (cost of one table)
-----
Solve for "c":
2c + 3t = 23
2c + 18 = 23
2c = 5
c = $2.50 (cost of one chair)
Answer:
your answer is positive 8/3
Step-by-step explanation:
When you are subtracting something by a negative number, it is the same as adding by a positive. For example, this equation would be solved like:
-2 1/3 + 5
Instead of -2 1/3 - (-5)
Hope that helps!
