A good way to find the answer to these questions is to find it algebraically. Let's call the first number 'n'.
n + (n + 2) + (n + 4) = 54
3n + 6 = 54
3n = 48
n = 16
Therefore the numbers are 16, 18, 20
I am guessing Jack is 51 and Lacey is 17.
Which equation am I looking at
Answer:
We have that y = 21 when x = 11.
Step-by-step explanation:
We solve this question by proportions, using a rule of three.
Since they vary inversely, we apply the inverse rule of three, that is, with lateral multiplication instead of diagonal.
33 - 7
y - 11
So
11y = 33 -7
y - 11
Dividing both sides by 11
Y = 3 * 7 = 21
We have that y = 21 when x = 11.
