No.
If a rational number can be an integer, x and y could be 5.5 and .5, or something that adds up to (number).0. This means, if the two non-rational numbers add up, they could be irrational, but the result isn't.
You will have to divide 15 and 5
-3/8 divided by 7/12
-3/8 times 12/7 ( 7/12 is switched because it is changing from division to multiplication)
-3/8 times 12/7= -9/14
Hope this helped
Answer : b= -1
just move -7 to the right side of the equal sign so you will know what b equals. So now -7 is a postive number ( 7) -8+7 = -1
so B= -1
It decreases by 1.28.
hope this helps!
