It is necessary when you are getting into multiplying from the outside of parenthesis and multiplying variables inside of parenthesis.
ex: 5(3 + 3x)
5 * 3 = 15
5 * 3x = 15x
so final set up would be 15 + 15x

5(-3x - 2) - (x - 3) = -4 (4x +5) + 13
S_A_V [24]
Start off by distributing the numbers into the parentheses:

5(-3x - 2) - (x - 3) = -4(4x + 5) + 13
-15x - 10 - (x - 3) = -16x - 20 + 13

(Note: It's super important to be careful when opening up negative parentheses! -(x-3) is not just - x - 3, it is actually -x + 3 since the negative is distributed in every number!)

-15x - 10 - x + 3 = -16x - 20 + 13
-16x - 7 = -16x - 7
-16x = -16x
0 = 0

There is an infinite number of solutions in this equation.

(When you get 0=0 when solving for a variable, that means that said variable will have infinite solutions, that is, any number plugged into the equation will work)

At 8:30 A.M.., Briana started filling a 2,800-gallon pond. At 10:30 A.M., she had filled 1,400 gallons. At what time will the po
Sati [7]

Answer:

12:30 pm

Step-by-step explanation:

8:30 am pond is empty

10:30 am pound is 1,400 gallons full

  time?    pound is 2,800 gallons full

from 8:30 to 10:30 are 2 hours so the rate of filling up is

             1,400 gallons in 2 hours

to have a whole pond filled we need another 2 hours because

in another 2 hours will have another 1,400 gallons so a pound full. 8:30 am + 2hours = 12:30 pm

8:30 am pond is empty

10:30 am pound is 1,400 gallons full

12:30 pm pound is 2,800 gallons full.

Complete the division problem by determining the number that should be placed in the box.
Assoli18 [71]
The solution 349 is given, and its number 3, 4 and 9 determine how many times 13 can be subtracted:

The first subtraction is 3x13 (x100) = 3900
The second subtraction is 4x13 (x10) = 520
The third subtraction is 6x13 = 78

So the answer is 520, which is also what you get when you subtract 78 from 598 of course.
