Answer: x = 72
Step-by-step explanation: Although the problem is saying "X over 8", this really signifies that the <em>x</em> is being divided by 8 which is what a fraction is, numerator divided by a denominator.
Let's first undo what has been done. Since our variable is being divided by 8, we'll undo that by multiplying by 8 on both sides. It's important to remember, whatever you do on one side,
you <u><em>must</em></u> do to the other side.
If you look now, the 8 in the numerator and the 8 in the denominator will divide out and it will leave us with our variable which is <em>x</em>. Working on the other side now, 9 x 8 is equal to 72 so <em>x = 72</em> is our answer.
We can check our answer by plugging a 72 back into the original equation. So we have 72/8 = 9 which is a true statement
so our answer is correct.

Answer:
The actual length of the bridge is 600 meters
Step-by-step explanation:
we know that
The scale on a map is
That means
1 unit on a map represent 40,000 units in the actual
1 cm on a map represent 40,000 cm in the actual
Remember that
so
we can rewrite the scale as
using proportion
Find out the actual length of the bridge in meters if the length of a bridge on a map is 1.5 cm.
Let
x ----> the the actual length of the bridge in meters
