Answer:

1) 18. 2) -5. 3) He did not subtract 12 from 36. 4) zero. 5) 5.

Step-by-step explanation:

Question 1:

x-7 = 11

x = 11+7 = 18.

Question 2:

11+z = 6

z = 6-11 = -5.

Question 3:

we have 12 + x = 36, we need to subtract 12 from 36 to find x.

Question 4:

x + 5 = x

5 = x-x

5 = 0.

this has no sense, then there are not solution.

Question 5:

6x = 30

x = 30/6

x = 5.

Amanda used 24 grams of paint to paint a wooden cube. When it dried, she cut the cube into 8 equal cubes. How many more grams of
kari74 [83]

Answer:

<h2>Amanda needs 72 grams of paint</h2>

Step-by-step explanation:

Notice that she already painted one face of each cube, that is, 8 faces in total, and she used 24 grams for that.

Now, there remain 3 faces per cube to be painted, which means there are 24 faces.

Then, we use the rule of three, if she used 24 grams of paint for 8 faces, how much grams of paint she would need to paint 24 faces?

24 \times \frac{24}{8}= 72 \ grams

Therefore, Amanda needs 72 grams of paint for the unpainted surfaces.

Given the linear system:
azamat

Answer:

y=x+1/2z+-1/2

Step-by-step explanation:

Let's solve for y.

2x−2y+z=1

Step 1: Add -2x to both sides.

2x−2y+z+−2x=1+−2x

−2y+z=−2x+1

Step 2: Add -z to both sides.

−2y+z+−z=−2x+1+−z

−2y=−2x−z+1

Step 3: Divide both sides by -2.

-2y/-2 = -2-z+1/-2

y=x +1/2z+-1/2
