Answer:
no solutions
Step-by-step explanation:
-4(5k-7) +2k= -2(9k+5)
Distribute
-20k +28 +2k = -18k -10
Combine like terms
-18k +28 = -18k -10
Add 18k to each side
-18k+18k +28 = -18k+18k -10
28 = -10
This is never true so there are no solutions
128.59943 rounds to about 128.599 because the next decimal is a 4 and your round down below 5.
Answer:
77
Step-by-step explanation:
as far as I can tell the steps between the given numbers are
-1
+4
-27
+16
1 can be expressed as 1³
4 can be expressed as 2²
27 can be expressed as 3³
16 can be expressed as 4²
my best guess is that next one is minus 5³ = -125
edit: technically the given steps can be expressed as
(-1)³
(-2)²
(-3)³
(-4)²
somewhat nicer pattern there
