Answer:

x= 6

Step-by-step explanation:

12+3x=30

3x+12=30

3x+12-12=30-12

3x=30-12

3x=18

3x divided by 3 = 18 divided by 3

x=18 over 3

18 divided by 3 is 6

x=6

Answer:

x = 6

Step-by-step explanation:

12 +3x = 30

Subtract 12 from both sides

3x = 30 - 12

3x = 18

Divide both side by 3

x = 18/3

x = 6

When p2 – 4p is subtracted from p2 + p – 6, the result is 5p-6 To get p – 9, subtract
jeka57 [31]
(p^{2}  + p - 6) - (x) = p - 9

 is what is asked.

So all you need to do is a value that will result to p - 9.

x = (p^{2} + p - 6) - p + 9  To isolate x we just transpose the values from the other side of the equation and do the opposite operation. 

Combine like terms and just copy the terms that do not have similar expressions:

p will cancel out because p - p = 0
-6 and + 9  will come together because they are like terms: -6 + 9 = 3 
p^{2} does not have a pair so it will remain as is. you will be left with:

p^{2}  + 3

Let us check:

   p^{2} + p - 6
-  p^{2} + 0 + 3  
----------------------------
   0 + p - 9    or p -9

HELP ASAP!!!!!!<br>What is the equation of a circle with center (1, -4) and radius 2?
sertanlavr [38]

Answer:

(x)^2+ (y+2)^2 = 49

Step-by-step explanation:

The standard form of a circle is

(x-h)^2+ (y-k)^2 = r^2 where (h,k) is the center and r is the radius

(x-0)^2+ (y--2)^2 = 7^2

(x)^2+ (y+2)^2 = 49

this is just a example

lmk if u get it

Answer: x=15

Explanation: you can set 2x+100 = 5x+55 because they are corresponding interior angles.

Work:
2x+100 = 5x+55
2x+100-5x = 55
2x-5x = 55-100
-3x = -45
divide by -3 to cancel the negative and get x by itself
x = 15

Hope this helped! :)
