Answer:

p = -3.5

Step-by-step explanation:

Simplifying

9 + -4(2p + -1) = 41

Reorder the terms:

9 + -4(-1 + 2p) = 41

9 + (-1 * -4 + 2p * -4) = 41

9 + (4 + -8p) = 41

Combine like terms: 9 + 4 = 13

13 + -8p = 41

Solving

13 + -8p = 41

Solving for variable 'p'.

Move all terms containing p to the left, all other terms to the right.

Add '-13' to each side of the equation.

13 + -13 + -8p = 41 + -13

Combine like terms: 13 + -13 = 0

0 + -8p = 41 + -13

-8p = 41 + -13

Combine like terms: 41 + -13 = 28

-8p = 28

Divide each side by '-8'.

p = -3.5

Simplifying

p = -3.5

5-2(a+3b)/2 When a=4 and b=1.
nirvana33 [79]

Hello macelynn190!

\huge \boxed{\mathfrak{Question} \downarrow}

\huge \tt \frac{5 - 2(a + 3b)}{2}

\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}

To solve this question we need to substitute the given values of 'a' & 'b' in the equation & then simplify it.

Given,

  • a = 4
  • b = 1

Now, substitute this in the place of 'a' & 'b'..

\large \tt \frac{5 - 2(a + 3b)}{2}  \\  =  \large   \underline{\underline{\tt \:  \frac{5 - 2((4) + 3(1))}{2} }}

Lastly, simplify it...

\large   \tt \:  \frac{5 - 2((4) + 3(1))}{2}  \\  =   \large \tt\frac{5 - 2(4 + 3)}{2}  \\  =  \large \tt \:  \frac{5 - 2(7)}{2}  \\  =  \large \tt \: \frac{5 - 14}{2}  \\  =  \large \tt\frac{-9}{2}  \\  = \large  \boxed{\boxed{  \bf \: -\frac{9}{2}=-4.5}}

  • The answer is <u>-</u><u>9</u><u>/</u><u>2</u><u> </u><u>or </u><u>-</u><u>4</u><u>.</u><u>5</u>
