To solve this question use a two variable system of equations.
First assign a variable to each number:
a=first number
b=second number
Then use the information in the problem to write two equations
They have a product of 20 translates to:
a x b =20
They have a sum of 9 translates to:
a + b =9
Use the method of substitution.
Isolate one variable in the 1st equation:
a= 20/b
Plug it into the 2nd equation:
(20/b) + b = 9
Solve for b:
b = 5
Now put b back into the 2nd equation:
a + 5=9
Solve for a:
a = 4
So the solution is 4 and 5.
4
12 and 8
They're 5 and 15.
The numbers are 20 and 9
The numbers are: 7 and 20
10 and 20.
It is 0.5
12 and 8
17 and 3 are two prime numbers whose sum is 20. Their product is 51.
4 and 5
5 and 4. 5x4=20 (product) 5+4=9 (sum)
They're 5 and 15.
A single number cannot have a sum or a product - a sum or product is used to compare two or more numbers.
The numbers are 20 and 9
The numbers are: 7 and 20
10 and 20.
16 + 20 = 36 16 x 20 = 320 The two numbers are 16 and 20.
asked to work out the product of two or more numbers, then you need to multiply the numbers together. If you are asked to find the sum of two or more numbers, then you need to add the numbers together.
