0.329 is a rational number because the decimal stops. If it had continued on and on with no particular pattern, it would have been irrational. It can be a fraction too (329/1000)...
127.5 is a rational number because again the decimal ends. It can also be converted into a fraction which is another sign that it is rational (127 1/2)...
-89 is a rational number because negatives are rational numbers. It is also in the category of an integer, which means that is a rational number also...
The last one is a non-perfect square, which means no number squared could ever give you 101. When you solve for it, it is also a non-terminating decimal.
X=420. You can find this by cross multiplying.
It's 35, I dont really need to work it out I know how to do it in my head lol but if you would like me too I will :)
Answer:
C) m = -63 is your answer
Step-by-step explanation:
Isolate the variable (m). Note the equal sign, what you do to one side, you do to the other.
Multiply 3 to both sides
-21 = (m/3)
(-21)(3) = (m/3)(3)
m = (-21)(3)
Combine like terms. Simplify.
m = -21 * 3
m = -63
C) m = -63 is your answer
