<span>Exponent
is a number used to express shorter equation; it is a number that says how many
times you are going to multiply the base number.
</span><span>
Exponents have several laws, here are
some:
=> x^1 = x
=> x^0 = 1
=> x^-1 = 1/x
=> x^m x^n = X^m+n
=> x^m/x^n = x^m-n
And since we were asked to write an
expression with a negative exponent that has a value between 0 and ½
=> 2^ -2 = ½

In case you want the working out -
You will want to put all these fractions over the same denominator, the lowest common multiple is 180
-2/9
180/9 = 20
20 x -2 = -40/180
A -7/12
180/12 = 15
15 x -7 = -105/180
B -1/15
180/15 = 12
12 x -1 = -12/180
C -1/3
180/3 = 60
60 x -1 = -60/180
D -1/9
180/9 = 20
20 x -1 = -20/180
-105 < -60 < -40 < -20 < -12
A < C < x < D < B
B and D
Answer:

Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
3.25 blocks
Step-by-step explanation:
6.5 * 1.5 = 9.75 blocks
9.75 - 6.5 = 3.25blocks
