They need to have common denomenators so change the fractions to 12/15 - 5/15 which is 7/15.
The answer is 160 because 312÷2 equals 156 and 156 is closer to 160 than 150
Hello!
Angles CAD and EAB are congruent.
The reason why is that they are vertical angles. Their points meet and therefore they are congruent.
I hope this helps!
We could do it with algebra. But we can also do it the long way, which is
shorter than the algebraic way.
The digit in the tens place is 3 times the digit in the units place.
So the number MUST be
31, or
62, or
93 .
It can't be anything else.
Now here they are again, with the reverse of each one:
31 . . . 13 The new number is 18 less.
62 . . . 26 The new number is 36 less.
93 . . . 39 The new number is 54 less.
Obviously, the original number is 62.
