5x-25=-10<br><br> Please HELP
solong [7]

Answer:

We simplify the equation to the form, which is simple to understand  

5x+25=10

We move all terms containing x to the left and all other terms to the right.  

+5x=+10-25

We simplify left and right side of the equation.  

+5x=-15

or this is another way

Simplifying

5x = 25 + -10

Combine like terms: 25 + -10 = 15

5x = 15

Solving

5x = 15

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Divide each side by '5'.

x = 3

Simplifying

x = 3

We divide both sides of the equation by 5 to get x.  

x=-3

If 5/9 of a tank can be filled in 2 minutes how many minutes will it take to fill the whole tank
asambeis [7]

Answer:

3 3/5 minutes

Step-by-step explanation:

Let one measure of volume be 5/9 of a tank, or (5/9)(tank).

We're interested in filling the whole tank, which we represent by (1)(tank) or (9/9)(tank.

Write and solve an equation of ratios:

 (5/9) (tank)        2 minutes

------------------- = ----------------

  (9/9) (tank)               x

Solve for x, which represents the number of minutes required to fill the whole tank:

(5/9)(x) = (9/9)(2), or (after simplifying) 5x = 18, or x = 18/5 (3  3/5 minutes)

The whole tank will be filled in 3  3/5 minutes.

3 times x=9
3x=9
divide both sides by 3
x=3
