Answer:
Step-by-step explanation:
First use distributive property: a(b + c) = a*b + a*c
3n - 6 = -8(6 + 5n)
3n - 6 = 6 * (-8) + 5n *(-8)
3n - 6 = -48 - 40n
Now add 40n to both sides
3n - 6 + 40n = -48 - 40n + 40n
43n - 6 = -48
Now add 6 to both sides
43n - 6 + 6 = -48 + 6
43n = -42
n = -42 /43
1 3/4 - 5/6r = 8/3
-5/6r + 7/4 = 8/3
-5/6r +7/4 - 7/4 = 8/3 -7/4
-5/6r = 11/12
(6/-5)*(-5/6r)=(6/-5)*(11/12)
=-11/10
r = -1 1/10
Answer:
=5x+3
Step-by-step explanation:
The Kingdom Eubacteria contain the ________ bacteria.
Answer:
∠ 1 = 160°, ∠ 2 = 20°
Step-by-step explanation:
The 2 angles are adjacent and supplementary, thus
∠ 1 + ∠ 2 = 180°, substitute values
5x + x - 12 = 180, that is
6x - 12 = 180 ( add 12 to both sides )
6x = 192 ( divide both sides by 6 )
x = 32
Thus
∠ 1 = 5x = 5(32) = 160°
∠ 2 = x - 12 = 32 - 12 = 20°
