# -6n-20=-2n+4 (1-3n) how do you solve it?

Simplify both sides of the equation.

−6n−20=−2n+4(1−3n)

−6n+−20=−2n+(4)(1)+(4)(−3n)(Distribute)

−6n+−20=−2n+4+−12n

−6n−20=(−2n+−12n)+(4)(Combine Like Terms)

−6n−20=−14n+4

−6n−20=−14n+4

−6n−20+14n=−14n+4+14n

8n−20=4

8n−20+20=4+20

8n=24

Divide both sides by 8.

8n/8 = 24/8

n=3

Answer: -6n - 20 = -2n + 4(1-3n)

-6n - 20 = -2n + 4 - 12n
-6n + 12n + 2n = 4+20

8n = 24     |:8

Factor f(x)= 3x³+5x²-47x+15 into linear factors given that -5 is a zero of f(x)

If  -5 is a zero then f(x) is divisible by (x + 5)

the quotient when F*x) is divided by x + 5  is  :-
3x^2 - 10x + 3
this factors to
(3x  - 1)(x  -  3)

so the answer is (x + 5)(3x - 1)(x -  3)

Determine the validity of the following argument: For students to do well in a discrete mathematics course, it is necessary that they study hard. Students who do well in courses do not skip classes. Students who study hard do well in courses. Therefore students who do well in a discrete mathematics course do not skip class.

Step-by-step explanation:

Let p= Students who do well in course do not skip class

q= Student who study hard do well in course

So p^q= Student who study hard and who do well in course do not skip class.

If p= true and q=true then p^q= true by discrete maths.

Beth has \$300 in her bank account. She buys x shirts for \$20 each. Wright and solve an inequality Beth can use to find how many shirts she can use to find how many shirts she can buy and still have \$100 in her account.

There will be 10 shirts she can use to find how many shirts she can buy and still have \$100 in her account.

What is inequality?

When both sides of a mathematical expression have mathematical signs that are either less than or greater than one another known as inequality

It is given that, Beth's bank account has \$300 and she spends \$20 on each of x shirts.

We must do the arithmetic operation known as the inequality, which entails multiplying the given data by x and then applying the inequality

The money for the x shirt is 20x and the rest of the money is 300-20x

The inequality helps them to find the shirts they can buy and still have \$100 in their account is,

=300-20x>100.

The number of shirts is obtained by solving the inequality as,

300-20x=100

20x = 300-100

20x=200

x=200/20

x=10

Thus, she can use the 10 shirts to determine how many shirts she can purchase while still having \$100 in her account.

300-100 to make sure that she still has the \$100 saved and Beth will have \$200 to spend on shirts.
200/20 is 10 So Beth can buy 10 shirts for \$20 dollars each with 100 dollars still left in her account. I HOPE THIS HELPS!!!
