14+14p=21 solve for p
11Alexandr11 [23.1K]

Answer: 0.5

Step-by-step explanation: In this problem, we're asked to solve the following equation for <em>p. </em>Let's first switch 14 and 14p around so we have 14p + 14 = 21.

<em />

To solve this equation for <em>p</em>, we must first isolate the term containing <em>p</em> which in this case is 14p.

Since 14 is being added to 14p, we need to subtract 14 from both sides of the equation.

14p + 14 = 21

        -14   -14

On the left side of the equation, the positive 14 and negative 14 cancel each other out and we have 14p. On the right side of the equation, we hav 21 - 14 which gives us 7.

Now we have the equation 14p = 7.

Since <em>p</em> is being multiplied by 14, to get <em>p</em> by itself, we divide both sides of the equation by 14.

On the left side of the equation the 14's cancel and we are left with <em>p</em>. On the right side of the equation, 7 divided by 14 is 0.5 which is our answer.

Therefore, p = 0.5 which is the solution for our equation.

Remember, you can always check your solution by substituting a number in for a variable to make sure the equation is true.

Belle made a scale drawing of a mural where 2 inches of the drawing represents 3 feet on the actual mural (scale 2 in. = 3 ft.).
ehidna [41]

Answer:

<h3>Very sorry if this is wrong but, I think the answer would be 48 inches. </h3>

Step-by-step explanation:

If every 3ft. = 2in. then I believe you would first divide the length and width by 3. So 6 divided by 3 is 2 and 18 divided by 3 is 6. Then you would multiply 2 and 6 by 2 since every 3ft = 2in.
