Corresponding measures have the same ratio.
.. (x -1)/4 = (2x +1)/10
.. 5(x -1) = 2(2x +1) . . . . . . multiply by 20
.. 5x -5 = 4x +2 . . . . . . . . eliminate parentheses
.. x = 7 . . . . . . . . . . . . . . . add 5 -4x
x = 7
#3
A(x) = 1000(1+.17)x
because the 17 percent would have to be changed to a decimal form
Answer:
10(x - 12)
Step-by-step explanation:
10(x - 12)
10x - 120 Distributive Property
<span>quotient of 63 and a number h would be 63/h
14 less than that would be 63 over h - 14</span>
