Step-by-step explanation:

-x - 3 = x + 3

Solving like terms

-3 - 3 = x + x

-6 = 2x

-6 / 2 = x

-3 = x

Answer:

-3

Step-by-step explanation:

You are trying to solve for x in this situation. So the first thing you want to do is choose a side (it doesn't matter in this situation bc there is an x on either side of the =) and isolate the x.

**I'm going to choose the left side cause why not** Add the -3 to both sides to get -x by itself:

-x + (−3) = x + 3

-x -3= x+3

* quick side note,  when you add a negative number to a positive, it has the same effect as subtracting

-x=x+6

Now -x is by itself but there is still another x, so combine like terms again:

-2x=6

Now simplify by dividing -2 to both sides:

x=-3

REY [17]

Answer:  (2p + 1.5d)  + (5*(2)) = T

Step-by-step explanation: (2p + 1.5d)  + (5*(2)) = T

Since there are no costs, i'll make up my own uwu;

Matinee = $5

Popcorn = $2

Drink = $1.5

T = total

(2p + 1.5d)  + (5*(2)) = T

2p ($2 for each bag of popcorn - p represents popcorn)

1.5d ($1.5 for each drink, - d represents drinks)

5*2 ( 5 * 2 because we are already given the amount of matinee tickets they buy.

A cylindrical cardboard mailing tube has a diameter of 5 in. and a height of 30 in. A total of 30% of the tube’s capacity is fil
olga2289 [7]
First is to get the volume of the cylinder.
Volume = pi * r^2 * H
Volume = 3.1416 * (5/2)^2 * 30
Volume = 589.05 in^3

30% is already filled.
Filled Space = 589.05 * 0.30
Filled Space = 176.715 in^3
Empty Space = 412.335 in^3

Next, get the volume of the sphere.
V = (4/3)*pi*r^3
V = (4/3)*pi*(0.6/2)^3
V = 0.1130976 in^3

Number of foams = Filled Space / V
Number of foams = 176.715 / <span>0.1130976 
Number of foams = 1562 Foams</span>
