<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.

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

Answer:
A
Step-by-step explanation:
let x= pizza y= soda
kay:
x+y=4
Mark:
6x+2y=18
From kay's equation
x= 4-y
substiute that into mark's
6(4-y)+2y=18
24-6y+2y=18
-4y= -6
y= 1.5
Plug in y= 1.5 in either equation to solve for x
x+1.5=4
x=2.5
So a pizza is 2.5 and a soda is 1.5
the answer must be A
