How do you solve 5v-4 over 10 equals 4/5

First you multiply each side by 10. Your new equation is: 5v-4 = 40/5. This simplifies to 5v-4=8.

Next, you add four to each side, getting 5v = 8+4 or 5v = 12.

Finally, you divide each side by 5. The answer is: v = 12/5

QUESTION POSTED AT 08/12/2019 - 10:46 PM

What is 345 written as a percent

Answer: 34500%.

Step-by-step explanation:

When we convert a number into percent , we multiply it by 100.

For example:  To convert 0.56 into percent, we have

0.56\times100=56\%

Let's take one more example , to convert 12 into percent , we have

12\times100=1200\%

The given number : 345

So to convert 345 into percent , we just multiply it by 100 , we get

345\times100=34500\%

Hence, 345 is 34500%.

Thus , the correct answer is 34500%.

Since the 3 is outside of the parentheses you would have to distribute it. This means that you multiply x by 3, then you multiply 4 by three to get 3(x) + 3(4). SO 3 time x equals 3x plus 3 time 4 equals 12
 This would give you 3x+12
