15/p;
4(px+1) / 4 = 64 / 4
= px+1 = 16
-1 -1
= px = 15; p ≠ 0
/p /p
= x = 15/p; p ≠ 0

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

Solution:

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

Ms. Lee wrote a test with 15 multiple choice short answer questions

Therefore,

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

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

The maximum number of points possible on the test is 100

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

Perform the addition. (3x² + 3x - 5) + (-7x² + 9)

lakkis [162]

The question is asking us to find the sum. To do this, let's first write the original equation and then take it from there.
$(3 x^{2} + 3x - 5) + (-7 x^{2} + 9)$ 
Use distributive property:
 $3 x^{2} + 3x - 5 - 7 x^{2} + 9$
Combine Like Terms:
$
-4 x^{2} +3x+4$
Therefore, the answer to your question is -4x² + 3x + 4. Hope this helps and have a fantastic day!
