Ms. Lee wrote a test with 15 multiple choice short answer questions. The multiple choice questions x are worth 5 points and the
hram777 [196]

x + y = 15 and 5x + 10y = 100 are the system of equations that represent this situation

<em><u>Solution:</u></em>

Let "x" be the number of multiple choice questions

Let "y" be the number of short answer questions

Worth of 1 multiple choice questions = 5 points

Worth of 1 short answer question = 10 points

<em><u>Ms. Lee wrote a test with 15 multiple choice short answer questions</u></em>

Therefore,

number of multiple choice questions + number of short answer questions = 15

x + y = 15 -------- eqn 1

<em><u>The maximum number of points possible on the test is 100</u></em>

Therefore, we frame a equation as:

number of multiple choice questions x Worth of 1 multiple choice questions + number of short answer questions x Worth of 1 short answer question = 100

x \times 5 + y \times 10=100

5x + 10y = 100 ------- eqn 2

Thus eqn 1 and eqn 2 are the system of equations that represent this situation

Two equations are given below:
stealth61 [152]

a is given to us so just plug a into the first equation:

b-3 - 3b =9

Add 3 to both sides:

b-3b=12

Combine like terms:

-2b=12

Divide by -2 to get b by itself:

b=-6

The only answer with b as -6 is the first one, (-9,-6)
