A number is multiplied by 5,and then 3 is subtracted from the product.the result is 12.find the number

Answers

The number is 3. The math is 5 x 3 = 15 15 - 3 = 12
The answer is 3 because you have to add 3 on both sides. Then you will get 5x =15 then to get X by itself you would have to divide by 5 on Both sides 5x/5 cancels its self out then your left with x 15/5=3 so you will get X=3 therefor the number is 3

5x-3=12

A high school teacher gives three regular exams during a semester and one final exam at the end of the semester. A student’s final grade is found by taking of the student’s three regular exam scores and then adding 40% of the student’s final exam score. Sophia earned scores of 78, 92, and 80 on the three regular exams and a score of 90 on the final exam. What is Sophia’s final grade?

Answers

To get an average score of 80% (out of four exams), a total of 4*80%=320% is needed, so the minimum required for the 4th test is 320-(75+97+60)=88.
To get an average score of 89% (out of four exams), a total of 4*89%=356% is needed, so the maximum required for the 4th test is 356-(75+97+60)=124, which is impossible.
So the next exam grade must range between 88 and 100 to get a grade b in the class.

Show that the binomial is a factor of the polynomial. Then factor the polynomial completely.

g(x)=x3−x2−20x; x+4
g(x)=

Answers

Answer:

g(x) = x(x - 5)(x + 4)

Step-by-step explanation:

Here the binomial is x + 4, indicating that a root is -4.  Note that x is common to all terms of g(x)=x3−x2−20x, so we can immediately write g(x) in partially factored form as

g(x) = x(x^2 - x - 20).  Since -20 = -5*4,

g(x) = x(x - 5)(x + 4)
