Answer:
Yes they are rational numbers
Step-by-step explanation:
Rational numbers are Any number that can be written in fraction form is a rational number. This includes integers, terminating decimals, and repeating decimals as well as fractions. ... So, any terminating decimal is a rational number.
I would use elimination. I would multiply 4x+3y=2 by 3 so the it becomes 12x+9y=6, and I would multiply the bottom equation by 4 so that it becomes 12x+8y=4. Because I am using elimination I have to get rid of one variable, I chose to get rid of X hence that the coefficient of X in each equation is now 12. i simply subtract both equations and get y by itself. y=2. I plug in Y to find x in either of the original equations, where I get x=-1. To check my work substitute the values of x and y in the other equation. 4(-1)+3(2)=2 -------> 2=2
15/25 = .6
25+30=55
.6*55=33
the distance is 33 feet across.

Answer:
Solution given:
Percent change of 87 to 63
is difference/(initial value)*100%
here
difference=63-87=-24
initial value=87
now
substituting value we get
percentage change=
%
=-24/87*100
=-27.58%
