the tens digit of a two digit is 7. if the order of the digit is reversed the new number obtained is 45 less than the original number. what is the number?​

9514 1404 393

  72

Step-by-step explanation:

The difference of 45 means the difference of digits in the number is 45/9 = 5. So, the ones digit is 7-5 = 2, and the number is 72.

__

If you want an equation, you can use x for the ones digit.

  70 +x = 45 +(10x +7)

  18 = 9x . . . . . . . . . . . . . subtract 52+x from both sides

  2 = x

The ones digit is 2, so the number is 72.

Further explanation

If you start with the two digits xy in a number and reverse them, the difference between the numbers xy and yx is ...

  (10x +y) -(10y +x) = 9(x -y)

This tells you the difference between the digit-reversed numbers is 9 times the difference between the digits.

the answer is 72

step-by-step explanation:

there has been genes found in the x chromosome of males that have been linked to [homo/hetero]sexuality. in addition to the reign of the x chromosome, a section of chromosome 8 has also been link to, "alot of ppl are so " these facts were proven true after a 2014 study of a gay male and his strait brother. according to newscientist.com,"chromosome 14 and is mainly active in the thyroid, but also the brain. called tshr, it makes a type of receptor protein that recognises and binds to a hormone that stimulates the thyroid. in this way, the gene plays an important role in controlling thyroid function. the fact that tshr seems to be involved in sexual orientation fits with evidence that thyroid function seems to be linked to sexuality."

in conclusion, "ppl are so gay" due to their genetics.
