Literally put a dot on 40 and 60 and connect the dots
Answer:
LCM(30;105)=210: least common multiple, calculated.
Step-by-step explanation:
30= 2x3x5
30 is not a prime, is a composite number;
105=3x5x7;
105 is not a prime, is a composite number;
*Positive integers that are only dividing by themselves and 1 are called prime numbers. A prime number has only two factors: 1 and Itself.
* A composite number is a positive integer that has at least one factor (divisor) other than 1 and itself.
Answer:
no real answer
Step-by-step explanation:
distribute the -4 and combine all of the like terms on the left side = r-8-4r, then -8-3r
then we have 7-3r=-8-3r
from here, we can already tell that there's no real answer. this is because the two -3r will cancel, leaving no variable.
since 7 doesn't equal -8, there is no answer.
if, for example, the value on both sides of the equal sign were the same after the variable was eliminated, then your answer would be all real numbers
If you subtract 71 and 27, you will get 44
Answer:
No
