Answer:
9/16 x^2y^3
Step-by-step explanation:
(3x^2y^5)^3/(2xy^3)^4
= 3^2 x^6 y^15 / 2^4 x^4 y^12
=9/16 x^(6 - 4) y^(15 - 12)
= 9/16 x^2y^3
(8-1.75) ÷ 5
(8.1.75) means the weight of the first apple slice subtracted from the apple's total weight.
The next part of the expression (÷ 5) means that the weight was divided equally by 5 so that there would be 5 equal parts.
Answer:
B) 20
Step-by-step explanation:
2808 lb. / 140 lb. ≈ 20
Answer:
x = - 12
Step-by-step explanation:
Given
+
= 1
Multiply through by (x + 4)(x - 2) to clear the fractions
x(x - 2) + 7(x + 4) = (x + 4)(x - 2) ← expand using FOIL
x² - 2x + 7x + 28 = x² + 2x - 8
x² + 5x + 28 = x² + 2x - 8 ( subtract x² from both sides )
5x + 28 = 2x - 8 ( subtract 2x from both sides )
3x + 28 = - 8 ( subtract 28 from both sides )
3x = - 36 ( divide both sides by 3 )
x = - 12
