The sum of two numbers is 56. the sum of the smaller and 5 times the larger is 192. find the numbers.
Kamila [148]

Let the numbers = x,y

x+y = 56      1st eqn

x+5y = 192   2nd eqn

56-y+5y = 192

4y = 136

y = 34

substitute that in 1st eqn, x = 56-34 = 22

So, smaller number = 22 & Larger number = 34

Answer:

Q4 = 4 || Q5 = 6 2/3 || Q6 = 4 4/7 || Q7 = 10 || Q8 = 3 1/3 || Q9 = 4 1/2

Step-by-step explanation:

In order to divide fractions, you just have to turn it into multiplying!
Flip the second fraction in the number sentence and then multiply!

Example: 5 divided by 6/7

Keep 5 as it is. Flip 6/7 to 7/6. 5 x 7/6 = 35/6

Now, simplify it! Simplifying is very simple. You just have to divide until they can't be divided anymore.

35/6 simplified = 5 5/6.

Reason:

How many 6's are in 35? 5 R: 5

So, then it would be 5 5/6.

Hope this helped and this was correct! If you have any more questions, I'll be here to answer them!
