First you take 15 and divide it by 5. That leaves you with 3. You also need to decide the x’s so you subtract the exponents (2-3=-1)

so you now have (y^10z^7)/(y^4z^10)3x^-1

Next we will divide the y’s.

Again, subtract the exponents (10-4=6) to get y^6

Now we have (3x^-1)(y^6) (z^7/z^10)

Last is z, we subtract the exponents again (7-10=-3) and get z^-3

Our answer is (3x^-1)(y^6)(z^-3)

Answer:

${x}^{2} - 18x - 21$

Step-by-step explanation:

${x}^{2} + 3 - 6(3x + 4)$

${x}^{2} + 3 - 18x - 24$

${x}^{2} - 21 - 18x$

$\boxed{\green{= {x}^{2} - 18x - 21}}$

a test has 20 multiple-choice questions with 5 choices each, followed by 35 true/false questions. if a student guesses on each q

Nuetrik [128]

Answer

There are 170 ways the student can answer the test.

Explanation

If there are 20 multiple-choice questions with 5 choices each, the student has 100 choices. The first question has 5 choices to pick from. The second has 5 as well. So does the third. Hopefully now you realize that you have to multiply the number of choices by the number of questions.

The same thing goes with the true/false questions. There are 2 choices for each true/false question, and there are 35 of those. 35×2 is 70. There are 70 ways to answer on the true/false questions.

Now combine the number of choices on the first part and the second part; 100+70 is 170.

Debra found that 6 of the 24 students in her class own a cell phone . What is the ratio of students that own a cell phone to stu

ale4655 [162]

6:18 students in Debra's class own a cellphone. Because there are 24 people in total. Minus the people who already own cellphones. Leaving 18 without cellphones. The ratio is people who have cellphones to people who do not.
24-6=18. Thus, the ratio would be 6:18
