Can someone please explain to me how to find the value of m? thanks-10 = -10 + 7m

                                        -10  =  -10  +  7m

Add  10  to each side:      0  =          7m

Divide each side by  7 :    0  =          m


Please take a second and just LOOK at the equation you started with.
It says: 

--  You have this number '-10' . 

--  Your number  -10  is going to be exactly the same size
     after you add 7 of something to it.

The ONLY way that could happen is if the 'something' is 'nothing' .

       ' m '  must be nothing.

To find the value of m you need to change the equation so it is x=m. First, we do inverse operations. Since multiplication came first, we do it last. So, -10 becomes +10. You add 10 to both sides. You get 0=7m because -10 cancels itself out. Then you divide by 7 on both sides. You get 0=m. You get this because 0 divided by 7 is 0. To check your work insert 0 into m's place. -10= -10 + 7(0). You get -10=-10. Now you know that m does indeed equal 0.

how do you write the quotient (9+i) over (9-i) in standard form? I need the answer but more importantly, I need to learn how to
Scorpion4ik [409]
Since they are the conjugates of each (9-a and 9+a are conjugates, or with any number replacing 9) , we multiply it by (9+i)/(9+i) to get (9+i)^2/(9-i^2)=(81+2i+i^2)/(9-(-1))=(81-1+2i)/(10)=80/10+2i/10=8+i/5. Conjugates work because they make i into i^2 (-1) without any of the sneaky i's in the middle!

Jorge is mixing a special shade of orange paint. He mixed 1 gallon of red paint with 3 gallons of yellow paint. Based on this ra
astra-53 [7]

Answer:

a. b. c. and d.  are true; e. is false

Step-by-step explanation:

1 gallon of red paint : 3 gallons of yellow paint

                                  &

1 gallon of red paint + 3 gallons of yellow paint = 4 gallons of orange paint

<em>a. 3/4 of a 4-gallon mix would be yellow paint.</em>

<em>True. 3 out of 4 gallon mix is yellow and 1 out 4 is red</em>

<em />

<em>b. Every 1 gallon of yellow paint requires 1/3 gallon of red paint.</em>

1 gallon of red paint : 3 gallons of yellow paint

divide by 3 in both sides of :

1/3 gallon of red paint : 3/3 gallons of yellow paint

<em>1/3 gallon of red paint: 1 gallon of yellow paint. True</em>

<em />

<em>c. Every 1 gallon of red paint requires 3 gallons of yellow paint.</em>

<em>True. </em>1 gallon of red paint : 3 gallons of yellow paint

<em />

<em>d. There is 1 gallon of red paint in a 4-gallon mix of orange paint.</em>

<em>True. 1 out of 4 is red and 3 out of 4 is yellow.</em>

<em />

<em>e. There are 2 gallons of yellow paint in an 8-gallon mix of orange paint.</em>

<em />

1 gallon of red paint + 3 gallons of yellow paint = 4 gallons of orange paint

Multiply by 2 each side of the equation

2(1 of red paint + 3 of yellow paint) = 2(4 of orange paint)

apply to each member of the parenthesis ()

2 of red paint + 6 of yellow paint = 8 of orange paint

Actually there are 6 gallons of yellow paint in a 8 gallon mix. So e. is false.
