Answer:
0.05 cm
Step-by-step explanation:
The least-significant digit in the given measurement is the one in the 0.1 cm number place. The "greatest possible error" is half the value of that number place, so is ...
(0.1 cm)/2 = 0.05 cm . . . . "greatest possible error"
_____
For questions of this sort, we make the (not always practical) assumption that the measurement is rounded perfectly to the nearest 0.1 cm.
Solution:
Note that:
16% = 0.160
so that, the correct answer is:
16% = 0.160
0.165
1/6 = 0.17
It mean 40 because it is in the tens place

Answer:
x=0.625
Step-by-step explanation:
-(-2x+1)=9-14x
distribute:
2x-1=9-14x
add 1 to both sides
2x = 10-14x
add 14x to both sides
16x=10
divide by 16 to isolate x
x = 0.625
check:
-(-2(0.625)+1) = 9-14(0.625)
0.25 = 0.25
Answer: x=-35/10
y=-4
Step-by-step explanation:
y = 3/2x +5/4
-2x+8y=-25
--------------------
replace y in second equation with: y = 3/2x +5/4
-2x+8(3/2x+5/4)= -25
-2x+12x+10= -25
10x=-35
x=-35/10
x=-3.5
7+8y= -25
8y=-32
y=-4
