Answer:
An apple costs $2 and a banana costs $1.
Step-by-step explanation:
x = cost of 1 apple and y = cost of 1 banana. So:-
2x + y = 5
2x + 3y = 7
Subtract the first equation from the second. We get:-
2y = 2
y = 1
and since 2x + y = 5, 2 x + 1 = 5 and
x = $2.

Remember
∛(ab)=(∛a)(∛b)
also
i¹=i
i²=-1
i³=-i
i⁴=1
so
∛-2i=(∛2)(∛-i)=(∛2)(i)=i∛2
Substitute each variable for the coefficient. Remember PEMDAS.
We can compare the two units or object performances by that.... even in the case of magnitude lower than zero....
