Answer:
a=8
c=5.5
Step-by-step explanation:
solve simultaneously:
2a + 4c = 38.00
3a + 3c = 40.50
times the first eq. by 3 and the second by 2
6a + 12c = 114
6a +6c = 81
subtract from one another
6a + 12c = 114
-6a +6c = 81
6c = 33
c=5.5
3a + 3x5.5 = 40.50
3a= 24
a=8
Whole numbers are sometimes integers.

<h3>Further explanation</h3>
- The set of natural numbers (also called the set of counting numbers) is denoted by N:

- Natural numbers together with zero called are called whole numbers. The set of whole numbers is denoted by W:

- The set of natural numbers are not enough for all the number problems in everyday life. For example, natural numbers cannot be used to write some winter temperatures, since such temperatures may be less than zero i.e., negative numbers.
- The set of integers are the union of the set of negative numbers with the set of natural numbers and zero. The set of integers is denoted by Z:

- The set of negative integers is denoted by Z⁻:

- The set of positive integers is denoted by Z⁺:

- The set of non-negative integers are the set of all positive integers together with zero.
- The set of non-positive integers are the set of all negative integers together with zero.
Conclusion:
Whole numbers are sometimes integers because negative integers are not part of whole numbers. In other words, whole numbers are not fully integers.

- The height of an airplane flight typically between 31,000 and 38,000 feet.
- Ice melts at 0⁰C.
- This diver is swimming at -20 m.

The solution of the equation is x= 3 and y = 2
Step-by-step explanation:
Given,
-3x-4y = -17 and
-x-3y = -9
The system of equation can be rewritten as
3x+4y = 17 ------eq 1 and
x+3y = 9 ------ eq 2
To solve for x and y
Multiplying eq 2 by 3 we get,
3x + 9y = 27
or, 3x = 27-9y
Putting this value of x into eq 1 we get,
27-9y +4y = 17
or, -5y = 17-27
or, -5y = -10
or, y = 2
Now put y=2 in eq 2 we get,
x = 9 - 3(2)
= 3
Hence the solution is x = 3 and y = 2
