Answer:
x/10=-30/100 : -3
5/35 = 1/a : 7
2/x = 100/15 : .3
12/k = 4/1 : 3
2/8 = g/4 : 1
Step-by-step explanation:
Given:
The tens digit of a two digit number is 5 greater the units digit.
If you subtract double the reversed number from it, the result is a fourth of the original number.
To find:
The original number.
Solution:
Let n be the two digit number and x be the unit digit. Then tens digit is (x+5) and the original number is:

Divide both sides by 55.


The unit digit is 2. So, the tens digit is
.
Therefore, the original number is 72.

or


Step-by-step explanation:
L is the number of hours Landen spent at the beach. Mateo spent 15% less time. This means he spent 85% of it. So 0.85 times L. We can also calculate it by subtracting the difference between the two kids. - 15%. 15% is 0.15L or
. We subtract by L-0.15L or as
. This fraction can simplify to
