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

156 revolutions in 180 seconds. how many revolutions in 2 minutes

Alona [7]

180 seconds is 3 minutes. If you divide 156 by 3, you will get 52. If you are looking for 2 minutes, you have to multiply 52 by 2. The answer is 104 revolutions in 2 minutes.

The answer is 12 because it’s a circle and that dot in the middle is the radius. so the radius is 6 which mean the diameter is 2x that making it 12
