Whats the answer to 1/5x=121 x=?

1 answer:

3 0

You have an algebraic expression in which you are solving for x. When you are solving for a variable, you need to isolate it all alone. Since you are multiplying by 1/5, you will have to undo it by multiplying by its reciprocal. In this case you are multiplying both sides by 5/1.

5/1 *1/5x = 121*5/1
x = 605

To check your answer, plug this value in for x and multiply it by 1/5. You should arrive at 121! Good luck!

Answer:

$\boxed{43}$

Step-by-step explanation:

I think the easiest way to solve this problem is by brute force: trial and error.

We must find numbers that when divided by

4 leave 3 (4n + 3)
5 leave 3 (5n + 3)
6 leave 1 (6n + 1)

Here is a list of multiples of the integer n that satisfy the three conditions. $\begin{array}{c|ccc}\mathbf{n} & \mathbf{4n+ 3} & \mathbf{5n + 3} & \mathbf{6n + 1}\\1 & 7 & 8 & 7\\2 & 11 & 13 & 13\\3 & 15 & 18 & 19\\4 & 19 & 23 & 25\\5 & 23 & 28 & 31\\6 & 27 & 33 & 37\\7 & 31 & 38 & \mathbf{43}\\8 & 35 & \mathbf{43} & 49\\9 & 39 & 48 & 55\\10 & \mathbf{43} & 53 & 61\\\end{array}\\\text{The only number that is common to all three lists is $\mathbf{43}$.}\\\text{The smallest possible number of muffins Mr. Baker could have baked is $\boxed{\mathbf{43}}$.}$

Check:

$43 \div 4 = 10R3\\43 \div5 = 8R3\\43 \div 6 = 7R1$

OK .

How is 21\30 bigger then 2\3

strojnjashka [21]

By reducing 21/30 you dived 21 and 30 by 3 and you will get 7/10. Is 7/10 larger than 2/3? If we put these fractions in decimal form we will see 7/10 turns into 0.7 and 2/3 turns into 0.667. So the answer is 21/30 is larger than 2/3.

Gina is travelling to the beach 20 miles away from her house.

On Ginas map her house and the beach are 4 inches apart

That is a distance of 20 miles is represented by the Ginas map in 4 inches

Therefore, on Ginas map one inch will be = 20/4 miles = 5 miles

So, the scale used for Gina's map is 1 inch = 5 miles

Hope this helps..!!

Thank you :)
