Solve this equation. -4(p+2)+8=2(p-1)-7p+15

ratelena [41]

Hey there!

First we have to $distribute$ !

$-4 (p +2) = +8 = 2(p - 1) -7p + 15 \\ -4(p) + -4(2) + 8 = 2(p) +-2 + -7p + 15$

Now, we have to $combine$ our like terms

$-4p + (-8 + 8) = 2p + (-7p) + (-2) + 15 
$

Once we solve all the $like-terms$ we get

$-4p = 5p +13$

Now, we have to $add$ $5p$ to each of your sides

$-4p + 5p \\ = -5p + 13 + 5p$

Solve that part of the equation

$p= 13$

Good luck on your assignment and enjoy your assignment

Find the nth term in the following sequence: 5, 7, 9, 11, 13...

vazorg [7]

Answer:

3=2n

Step-by-step explanation:

Formula: Tn=T1+(n-1)*d

Tn is the nth term

T1 is the first number of the sequence

n is the nth term as well

D is the common difference

now its Tn=5+(n-1)*2

now solve that so its

Tn=5+2n-2

now its

Tn=3+2n

that's it
