Answer:

f=8/5

Step-by-step explanation:

f*2+=f7

2f-7f=-8

-5f=-8

6/3=22/x (i really need help
Tpy6a [65]
Well, we can begin by simplifying.

6/3 equals 2, so we make the left side 2.

2 = 22/x

x is being divided by 22, so to undo it, we multiply.

therefore it becomes:

2 times x = 22
2x = 22

we can divide by 2 on both sides.

we are left with


x = 22/2

22/2 is 11, so x = 11.

hope this helps!

Complete each ordered pair so that it is a solution of the given linear equation. x - 3y=4;(.-3), (-11, ) The first ordered pair
AURORKA [14]

Answer:

Step-by-step explanation:

x - 3y = 4

x - 3(-3) = 4

x + 9 = 4

x = -5

(-5, -3)

-11 - 3y = 4

    - 3y = 15

        y = -5

(-11, -5)

I don't see how (0, -3) could be a solution to the equation.

P=2l+2w. solve for w. show all steps. please
aliina [53]

Answer:

Step-by-step explanation:

You need to get w on one side by itself.

Start out by subtracting 2l from both sides.

p−2l=2w.

Now since w is being multiplied by 2 we need to divided both sides (all terms) by 2.

w=p2−I
