Answer:
0.153
Step-by-step explanation:
We have been given that Mafalda has a save percentage of 0.738 so far this hockey season. Last season, her save percentage was 0.585.
To find improvement in Mafalda's save percentage we will subtract last season's save percentage from this season's save percentage.
Therefore, Mafalda's save percentage improved by 0.153.
So we want to solve <span><span><span>2x </span>− 40 </span>= <span>3y </span></span>for x<span><span><span><span>2x </span>− 40 </span>+ 40 </span>= <span><span>3y </span>+ 40</span></span>(Add 40 to both sides!)<span><span>2x </span>= <span><span>3y </span>+ <span>40
Now divide both sides by 2!
</span></span></span>
Now substitute
Which then gives us..
<span><span>2y </span>= <span><span>−<span>6y </span></span>− 32</span></span>(Make sure to simplify both sides of the equation)<span><span><span>2y </span>+ <span>6y </span></span>= <span><span><span>−<span>6y </span></span>− 32 </span>+ <span>6y</span></span></span>(Now add 6y to both sides)<span><span>8y </span>= <span>−<span>32
Now divide both sides by 8
</span></span></span>
Now we have to substitute -4 for y in
So we end up getting...
<span>x = <span><span>14<span> and </span></span>y </span></span>= <span>−<span>4.
</span></span>Hope this helps!
