im not sure the examples,, but here's how to find one that's equal.
-say you have 5/6 ,, literally just take each number and multiply by
another (lets say 2.)
-----ie: 5x2=10 6x2= 12.
-next you set the products up as a fraction. - 10/12
then you have your answer! (you can do this with whatever number)
He starts saving $ in January to buy a gift in June. (which is 6 months, or 5 months not including June)
Each month he saves 2/3 of his allowance, which is $14.
[his allowance each month is $21, 2/3 of his allowance is $14]
(you multiply 21 by 2/3 = 42/3 = 14)
The gift he wants to buy is $110
x = the number of months
y = total cost
14x = y
14x = 110 [he saves $14 each month, he wants to have a total of $110 to buy a gift]
Plug in 6 for x in the equation
14(6) = 110
84 = 110 (He is $26 short, so saving either for 5 or 6 months will not get Ian $110)
Ian will not have enough money because he is $26 short for 6 months or $40 short for 5 months. (you can decide whether you want to go by 5 months or 6(including June), sorry for the confusing answer)
Answer:
Step-by-step explanation:
P(x) = x² - 1 and Q(x) = 5(x - 1)
(P - Q)(x) = x² - 1 - 5(x - 1)
= x² - 1 - 5x + 5
= x² - 5x + 4
