Answer:
Jason = <span>20yrs.old</span>
Mandy = <span>15yrs.old</span>
Explanation:
Let
J = Jason's age
M = Mandy's age
<span>J+M=35</span> ..... eq. 1
<span>J−10=2<span>(M−10)</span></span> ..... eq. 2
From eq. 1
<span>J=35−M</span>
Substitute this in eq. 2.
<span><span>(35−M)</span>−10=2<span>(M−10)</span></span>
<span>35−10−M=2M−20</span>
<span>35−10+20=2M+M</span>
<span>45=3M</span>
<span><span>453</span>=<span><span>3M</span>3</span></span>
<span>15=M</span>
<span>J=35−M</span>
<span>J=35−15</span>
<span>J=<span>20</span></span>

Answer:
Math
Explanation:
Which of the following is something all models use to determine relationships?
The answer would be math.
If you’ve ever had a savings account, you likely know that a few cents in interest every month barely adds up. The goal is “compounding returns,” which simply means that the interest you earn each month earns additional interest, which then earns even more interest. But although a savings account will help with that, you may be lucky enough to be able to afford a cup of coffee every 10 years or so at that rate. Instead, it’s important to find a way to invest your money in a high-interest account that will earn compounding returns.
I hope this helps you out ;)
