Distribute the -2 first on the right side of the equation
-3x-4=-2x+(-4)-x
-3x-4=-2x-4-x
Then add all like terms
-3x-4=-3x-4
Put all like terms on the same side ( variables on one side and constants on one side) when doing that remember when move a term from the original position it changes sign.
-3x+3x=4-4
0=0
There is no solution for x.

Trava [24]

Answer:

(5/24) gallons of gas to mow the side yard

Step-by-step explanation:

We can easily solve this proble by applying a rule of three

5/16 gallons of gas  ---------------------------------  for 1 backyard

x  gallons of gas ------------------------------------- 2/3 backyard

x = ((2/3)/1)*(5/16) gallons of gas

x = ((2/3))*(5/16) gallons of gas

x = ((10/48) gallons of gas

x = (5/24) gallons of gas

I need help with math if you don't know the answer get out of the question and don't answer it and give the wrong answer or some
velikii [3]

Answer:

Step-by-step explanation:

Frequency table for the height of the seedlings,

Height (in inches)        Number of seedlings

          \frac{1}{2}                                      2              

          \frac{3}{4}                                      4

          \frac{5}{8}                                      2

          \frac{7}{8}                                      2

Now we can draw the line plot as attached.

Average height of the seedlings = \frac{2(\frac{1}{2})+4(\frac{3}{4})+2(\frac{5}{8})+2(\frac{7}{8})}{2+4+2+2}

                                                      = \frac{1+3+1.25+1.75}{10}

                                                      = \frac{7}{10}
