The answer is y = 2x + 3.
x - Kay's age
y - Jane's age
m - Mary's age
<span>Jane is 3 years older than Mary: y = m + 3
</span><span>Mary is twice as old as Kay: m = 2x
</span><span>
y = m + 3
m = 2x
Substitute m in the first equation:
y = 2x + 3

Answer:
The answer is 58333.3333333
Step-by-step explanation:
You have to divide what the total amount invested divided by 3.
965.4 because .38 is in the hundredth place so you round the three. Any number greater than 5 will bump up the number before it. So eight bumped 3 up to 4.
57-8=49
So then 7y=49
Y=1 so 2y=2
