Answer:
Sakura spoke for 2 minutes in Hungarian and for 3 minutes in Polish.
Step-by-step explanation:
Let H represent the number of minutes Sakura spoke in Hungarian and P represent the number of minutes Sakura spoke in Polish.
We have been given that Sakura speaks 150 words per minute on average in Hungarian, so total Hungarian words spoken in H minutes will be 150H.
Sakura also speaks 190 words per minute on average in Polish, so total Polish words spoken in P minutes will be 190P.
Sakura spoke 270 more words in Polish than in Hungarian. We can represent this information in an equation as:
[tex]190P-150H=270...(1)[/tex]
Sakura spent 5 minutes total giving both instructions. We can represent this information in an equation as:
[tex]H+P=5...(2)[/tex]
We will use substitution method to solve our system of linear equations.
From equation (2) we will get,
[tex]H=5-P[/tex]
Upon substituting this value from equation (1) we will get,
[tex]190P-150(5-P)=270[/tex]
[tex]190P-750+150P=270[/tex]
[tex]190P-750+750+150P=270+750[/tex]
[tex]190P+150P=270+750[/tex]
[tex]340P=1020[/tex]
[tex]\frac{340P}{340}=\frac{1020}{340}[/tex]
[tex]P=3[/tex]
Therefore, Sakura spoke for 3 minutes in Polish.
Let us substitute P=3 in equation (2) to solve for H.
[tex]H+3=5[/tex]
[tex]H+3-3=5-3[/tex]
[tex]H=2[/tex]
Therefore, Sakura spoke for 2 minutes in Hungarian.
