1200 milligrams because 400 times 3 would equal a full 24 hours
Answer:
Infinite solutions.
Step-by-step explanation:
Let's solve your system by substitution.
3y=9x+15;3x−y=−5
Rewrite equations:
3x−y=−5;3y=9x+15
Step: Solve 3x−y=−5 for y:
3x−y=−5
3x−y+−3x=−5+−3x(Add -3x to both sides)
−y=−3x−5
−y −1 −1=−3x−5
(Divide both sides by -1)
y=3x+5
Step: Substitute 3x+5 for y in 3y=9x+15:
3y=9x+15
3(3x+5)=9x+15
9x+15=9x+15(Simplify both sides of the equation)
9x+15+−9x=9x+15+−9x(Add -9x to both sides)
15=15
15+−15=15+−15(Add -15 to both sides)
0=0
Hello lucker
1. The answer would be "-15" since integers are composed of whole numbers and negatives.
2. The statement "<span>Every real number is a rational number." is false, since real numbers are composed of both rational and irrational numbers.
3. The number "</span><span>8.52624 . . ." because this is the only non-terminating number, which makes it the only irrational number on the list.
4. "</span><span>Irrational numbers cannot be classified as rational numbers." is the only correct statement. No irrational numbers can be rational numbers, and the opposite is also true.
5. Only the statement "</span><span>Every irrational number is a real number.</span>" is true.
