Answer: each apple is 5 ounces
Step-by-step explanation: 10/32=0.3125. So each apple is 0.3125 pounds. Converted to ounces that’s 5 ounces each apple.
-------------------------------------------------------
Equation Given :
-------------------------------------------------------
16x² = 121
-------------------------------------------------------
Take away 121 from both sides:
-------------------------------------------------------
16x² - 121 = 0
-------------------------------------------------------
Make each term a perfect square
--------------------------------------------------------
(4x)² - (11)² = 0
--------------------------------------------------------
Apply algebraic rule : a² - b² = (a + b)(a - b)
--------------------------------------------------------
(4x + 11) (4x - 11) = 0
-------------------------------------------------------
Apply zero product property :
-------------------------------------------------------
4x + 11 = 0 or 4x - 11 = 0
--------------------------------------------------------
Solve for x :
--------------------------------------------------------
4x = - 11 or 4x = 11
x = -11/4 or x =11/4
--------------------------------------------------------------------------
Answer: x = -11/4 or x = 11/4
--------------------------------------------------------------------------
The answer is 168. 12% is also 0.12. 150(0.12) is 18. 150+18=168
W^2 + w - 20 = (w + 5)(w - 4)
(w - 3) (w - 4) w^2 - 7w + 12
---------- * -------- = ------------------
(w + 5) (w - 4) w^2 + w - 20
