Answer:

5/6w=2/3

5/6(4/5)=2/3

20/30=2/3

20/30=10/15=2/3=2/3

Proof:

5/6w=2/3

6/5*5/6w=2/3*6/5

30/30w=2/3*6/5

w=12/15=4/5

Hope this helps ;) ❤❤❤

x+2y+2z=3. 2x-2y-z=3. x-2z=-5​
d1i1m1o1n [39]

Answer:

x = 1, y = -2, z = 3.

Step-by-step explanation:

x + 2y + 2z = 3      A

2x -2y - z = 3         B

x - 2z = -5              C

If we add equations A and B we eliminate y:

3x + z = 6       E

Multiply E by 2 :

6x + 2z = 12    F

Adding C and F we get:

7x = 7

x = 1.

Plug this into equaton C:

1 - 2z = -5

-2z =  -5 - 1 = -6

z = 3.

Now plugging x = 1 and z = 3 in equation A:

1 + 2y + 2(3) = 3

2y = 3 - 1 - 6 = -4

y = -2.

A. Is the attached image. The slope is 7.5x

b. 1 = 7.5x

x = 1.33333…

This is hours so we must multiply this by 60

I need to find a number that the "n" represents. The problem is 9/12=n/32
likoan [24]

The given equation is

\frac{9}{12} = \frac{n}{32}

Here we have to solve for n. First we need to get rid of the denominators and for that we do cross multiplication .

9*32 = 12n

Now we need to isolate n. And for that we need to get rid of 12, by dividing both sides by 12

\frac{9*32}{12}=n

\frac{288}{12} =n

n=24

And that's the required value of n .
