If you multiply a number by 3 and then subtract 5, you will get 40 what is the number
Paul [167]

Answer:

Number  = 15.

Step-by-step explanation:

Given : If you multiply a number by 3 and then subtract 5, you will get 40.

To find : what is the number.

3x = 45 .

On dividing both sides by 3

x =  15.

Therefore, Number  = 15.

Find Z for the following proportion
krek1111 [17]
This is the simplest proportion i have seen.
This is how we do it:
\frac{z}{7} = \frac{1}{7}
The answer surprisingly is obvious, z = 1
But we can still do cross multiplication

7z = 7
Divide by 7 to isolate z

\frac{7z}{7} =  \frac{7}{7}
7 and 7 cancels out
z = 1
