Answer:
-2
Step-by-step explanation:
-|3n| - 2 = 4
|3n| = -6
3n = -6 or 3n = -(-6)
n = -2 n = 2
Since 2 is not part of the options, -2 is the only correct answer
2)
32/28=w/7
you cross multiply one denominator by the other numerator so
32(7)=(28)(w)
simplify
224=28w
divide 28 from both sides to get w alone
8=w
4)
36/21=24/s
cross multiply just like in the last problem
(36)(s)=(21)(24)
simplify
36s=504
divide 36 to get s alone and essentially solve for s
S=14
A line is infinitely long but is only one-dimensional.
A solid is three-dimensional but not infinite.
Geometric space is infinite but is three-dimensional.
So, that leaves a plane, which is two-dimensional and infinitely large. The answer is A plane!
Answer:
C.(2.5,3.5)
Step-by-step explanation:
Graphing both equations, we can see where they cross
The x coordinate is about 2.5 and the y coordinate is about 3.5
Answer:
Step-by-step explanation:
I can solve 4 for you.
a - 3a
1a - 3a
= 2a
