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.

3/5 ✖️ 10/7
=30/35
=6/7
The area for rectangle is (l x w) or (length times width) or (length x width)
*just in case you get confused
so the length is 10, and the width is 2.5 so you plug in.
10 x 2.5 = 25
your answer is 25 mm²

Answer:
B. -x^2 + 3x + 7
Step-by-step explanation:
(f -g)(x) = f(x) -g(x) = (3x +1) - (x^2 -6) . . . . substitute the functions
= 3x +1 -x^2 +6 . . . . . . . eliminate parentheses; next, collect terms
= -x^2 +3x +7 . . . . . matches choice B
