Answer: Xavier bought 2 apples and 9 bananas.
Step-by-step explanation:
Let x represent the number of apples that Javier bought.
Let y represent the number of bananas that Javier bought.
At the store, he bought $6 worth of apples and bananas. Each apple costs $0.75 and each banana costs $0.50. This is expressed as
0.75x + 0.5y = 6 - - - - - - - - - - - - 1
He bought a total of 11 apples and bananas altogether. This means that
x + y = 11
Substituting x = 11 - y into equation 1, it becomes
0.75(11 - y) + 0.5y = 6
8.25 - 0.75y + 0.5y = 6
- 0.75y + 0.5y = 6 - 8.25
- 0.25y = - 2.25
y = - 2.25/ - 0.25
y = 9
x = 11 - y = 11 - 9
x = 2
Answer: -2,4,-8,16,-32,...

The symbol which correctly compares the numbers is <, i.e less than.
Given the expression is ∛27 = 21/5
Mathematicians refer to the process or method of comparing numbers as a way of figuring out if one number is less than, equal to, or higher than another one given their values.
first get the values of the numbers
∛27 = 3×3×3 = 27
hence we get it as 3
now for 21/5 = 4.2
hence the second value is greater than the first value and but as the expression says the first value is less than the second value.
Hence the correct expression is:
3<4.2
Therefore, the symbol which compares the correct form of expression is < that is less than.
