Answer: z = 3
Step-by-step explanation: To solve this equation for <em>z</em>, we can first combine our like terms on the left side of the equation. Since 12 and 7 both have <em>z</em> after their coefficient, we can subtract 12z - 7z to get 5z.
Now we have 5z - 2 = 13.
To solve from here, we add 2 to the left side of the equation in order to isolate 5z. If we add 2 to the left side, we must also add 2 to the right side. On the left side, the -2 and +2 cancel out. On the right, 13 + 2 simplifies to 15.
Now we have 5z = 15.
Solving from here, we divide both sides of the equation by 5 to get <em>z</em> alone. On the left side, the 5's cancel out and we are simply left with <em>z</em>. On the right side, 15 divided by 5 simplifies to 3 so we have z = 3.

Answer:
The length of the actual building is 112 meters long.
Step-by-step explanation:
The key words we need to know are these : scale is 1 millimeter = 7 meters, and 16 millimeters long.
The question is asking for the building's actual height.
To solve this, we need to set up a ratio, have the scale being one ratio and the other 16 millimeters over blank. It's going to look like this :
= 
We need to make sure all the units are lined up - the mm parts of the ratio are next to each other.
Now that we have our ratio set up we can cross product to solve for x.
1(x) = 16(7)
x = 112
So x is 112, or the length of the actual building is 112 meters long.

heights or lengths relative to the standards that they signify. The bars can
be designed vertically or horizontally. A vertical bar chart
is occasionally called a line <span>graph</span>
