What is the answer to this equation 4(x-3)=20

Answer and Step-by-step explanation:

[tex]\frac{5}{x-9}[/tex]

The domain is all real numbers except 9 (positive)

This is because we can't have 0 in the denominator, and when x equals 9, then the denominator is 0. Anything divided by 0 is undefined, which is why 9 (in this equation) is not included.

Answer:

What you want to do is solve for m in whichever equation it's easier to so in, then substitute that in to the other equation. For instance:

X=3m-4

Y=6-m

Solve the 2nd equation to get m=6-y

Plug that into the first equation to get x=3(6-y)-4

X=18-3y-4

X-14=-3y

14-x=3y

Y=(14-x)/3

Answer:

137 degrees

Step-by-step explanation:

By using the fact that a triangle contains 180 degrees and angles made by the same lines are congruent we can find out that the top angle in the first triangle is 45 degrees. We can then figure out that the missing angle in that same triangle is 75 degrees by adding 45 and 60 and subtracting that from 180. Then we add that 75 degrees to 68 degrees to get 143 degrees which we can use to discover that the corner of the triangle that connects to the other triangle is 37 degrees. From there we know that triangles contain 180 degrees, so the remaining value is 43 and with this we can discover that the value of the asked for angle is 137 degrees.

Answer:

x = 20

Step-by-step explanation:

6(x-8)=72

6x-48=72

6x-48+48=72+48

6x=120

6x/6=120/6

x = 20

hope it's helpful ❤❤❤❤❤❤

THANK YOU.

Answer: x=20

Step-by-step explanation:

Distribute the 6 to the values in the parentheses

6x - 48 = 72

Add 48 to each side

6x = 120

Divide each side by 6

x = 20

Answer:

37.80

Step-by-step explanation:

divide 210 by 5 to find the cost of one person, 42 dollars. 10 percent of 42 is found by multiplying 42 to the decimal form of 10 percent, 0.1.

4.2 is the amount you need to subtract from 42 to get you 37.80. boom roasted. (dont hate me if I'm wrong plz)

Answer:

q = [tex]\frac{8}{3}[/tex]

Step-by-step explanation:

The point of intersection (3, 1 ) is the solution to both equations

Using

y = qx - 7 and substituting x = 3, y = 1

1 = 3q - 7 ( add 7 to both sides )

8 = 3q ( divide both sides by 3 )

[tex]\frac{8}{3}[/tex] = q

Answer:

a = 6

Step-by-step explanation:

120 = 3 + 3(7a - 3)   (by PEDMAS, expand parentheses first by distributive property)

120 = 3 + 7a(3) - 3(3)

120 = 3 + 21a - 9

120 = 21a - 6    (add 6 to both sides and rearrange)

21a = 120 + 6

21a = 126   (divide both sides by 21)

a = 126/21

a = 6

Step-by-step explanation:

120-(3+3*(7*a-3))=0

Step by step solution :

STEP

:

Equation at the end of step 1

120 - (3 + 3 • (7a - 3)) = 0

STEP

3

:

Pulling out like terms :

3.1 Pull out like factors :

126 - 21a = -21 • (a - 6)

Equation at the end of step

3

:

-21 • (a - 6) = 0

STEP

4

:

Equations which are never true:

4.1 Solve : -21 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

4.2 Solve : a-6 = 0

Add 6 to both sides of the equation :

a = 6

One solution was found :

a = 6

Answer:

D) {-2, 1, 2, 5}

Step-by-step explanation:

The "output" of a function will never be an ordered pair, so we can immediately eliminate options A and B.

In this case, the output refers to the y-values of the function.  

Since the ordered pairs are: (-2, 5), (-1, 1), (2, -2), and (5, 2), we see that the output of this function is: 5, 1, -2, 2.

Thus, choice D is correct.

Answer: X equals 7

Step-by-step explanation:

Answer:

7

Step-by-step explanation:

First you want to simplify the equation

8x + (-5) = 23 + 4x

-5 + 8x = 23 + 4x

Then solve for x, but before we do that we !!!must!!! move all terms that have x  to the left. Everything else would go to the right.

So we add -4x to both sides ..

-5+ 8x + (-4x) = 23 + 4x + (-4x)

-5 + 4x = 23 + 4x + (-4x)

-5 + 4x = 23 +0

-5 + 4x  = 23

Then add 5 to both sides of the equation:

-5 + 5 + 4x = 23 + 5

0 + 4x = 23 + 5

4x = 23 + 5

4x = 28

Then divide each side by 4:

x = 7

And there you have it. The answer is 7. Hope this helps! :)
