Solve the system of equations by elimination:<br> 2 - 5y = 1<br> 2x + 5y = 17
lesantik [10]

Answer:

X = 8 And y = 1/5

Step-by-step explanation:

add equaction i and education ii,

2 -5y = 1

2x +5y = 17

------------------

2+2x = 18

or, 2x = 18 - 2

or X = 16/2

or X = 8

Again from equation i,

2 - 5y = 1

or, -5y = 1 - 2

or, -5y = -1

or, y = -1/-5 (cut the subtraction sign)

or, y = 1/5

Of the students in your class, 12% are left-handed. What fraction of the students are left-handed? Are there more right-handed o
kvv77 [185]
The left-handed students
12% are left handed, percent means per hundred. Change percent into per 100.
12% = \dfrac{12}{100}

Then simplify the fraction by dividing the numerator and denominator by 4
\dfrac{12}{100}
= \dfrac{12:4}{100:4}
= \dfrac{3}{25}
This is the fraction showing the proportion of the left-handed students

The right-handed students
Determine the fraction showing the proportion of the right-handed students
1 - the left-handed
= 1 - \dfrac{3}{25}

Equalize the denominator to 25
\dfrac{25}{25} - \dfrac{3}{25}

Simplify
\dfrac{21}{25}
This is the proportion of the right-handed students

<span>Are there more right-handed or left-handed students?
There are more right-handed students than the left-handed students, because 21/25 is more than 3/25</span>
