Answer: A is 10; B is 6
Step-by-step explanation:
Let the sum of a whole number A and a whole number B = 16
A + B = 16
The ratio A: B = 5: 3
Possible whole numbers whose ratio gives 5 : 3 are 10 and 6, 15 and 9, 20 and 12 etc. However, since A + B must equal 16, only 10 and 6 fulfil the condition
So, let A be 10, while B is 6
10 + 6 = 16
The ratio 10 : 6 = 10/6 = 5/3
Thus, the value of A is 10; while B is 6
Answer:
B.
Step-by-step explanation:
Step 1: Cross-multiply
x² + 2x = 4x²
Step 2: Isolate <em>x</em>'s
2x = 3x²
0 = 3x² - 2x
Step 3: Factor
x(3x - 2) = 0
Step 4: Find roots
x = 0, x = 2/3
Step 5: Double check answers.
When you do so, you should see that only x = 0 works. And we have our answer!
You can add the numbers of those people to come up with the total.
