Simplify the following:
(-6 (-8)×2×3 x x x x)/(3×4)
(8 x×2 x (-6) x×3 x (-1))/(3×4) = (8 x^4×2 (-6)×3 (-1))/(3×4):
(-6 (-8)×2×3 x^4)/(3×4)
8×2 = 16:
(-6 (-3)16 x^4)/(3×4)
16 (-6) = -96:
(-3-96 x^4)/(3×4)
-96 (-3) = 288:
(288 x^4)/(3×4)
3×4 = 12:
(288 x^4)/12

Answer: 24 x^4
base, b = 45m
angle of elevation, aoe = 82deg
height at 86th floor, h1
height above 86th floor, h2 = 123m
total height, h = h1 + h2
using
tan (aoe) = h1/b
=》 h1 = tan (aoe) × b = tan 82 x 45 = 320.2
h = h1 +h2 = 320.2 + 123 = 443.2m
Price / weight = unit price
product A : 1.36 / 8 = 0.17 per oz
product B : 3.20 / 16 = 0.20 per oz
product A has the lower unit price
-4 < 4(6y - 12) - 2y
<em><u>Distributive property.</u></em>
-4 < 24y - 48 - 2y
<em><u>Combine like terms.</u></em>
-4 < 22y - 48
<em><u>Add 48 to both sides.</u></em>
44 < 22y
<em><u>Divide both sides by 22.</u></em>
2 < y
The value of y is greater than the value of 2.
Answer:
x=-11
y=-1
Step-by-step explanation:
x=4y-7
2x+9y=-31
2(4y-7)+9y=-31
8y-14+9y=-31
17=-31+14
17y=-17
y=-1
x=4(-1)-7
x=-11
