Because if the number was rational then we can tell by looking at the numbers. The rational number should be one number or a repeating decimal or terminating number. plus because if a number was like this 5.7696... that means its irrational because we dont know the end of the number. The rational numbers are terminating numbers or either decimal or repeating numbers because we know the end of those numbers.
Observe.
6/2(1+2)
6/2(3)
6/6
1
Thus, the answer is: 1
yes, I'm pretty shure they do
Answer:
24 yards, $77.40
Step-by-step explanation:
1) brown braid : 4*2.40 = $16.80
black lace : 7*2.40 = $29.40
gold ribbon : 13*2.40 = $31.20
2) 4 + 7 + 13 = 24 yards <
3) 16.80 + 29.40 + 31.20 = $77.40 <
3n+4=-5
do the opposite of adding 4. this means you have to subtract 4 from 4. whatever you do to the problem, you must do to the answer. now subtract 4 from -5.
-5-4=-9
since 4-4=0, we can take 4 out of the equation. now you have:
3n=-9
now divide -9 by 3
-9/3=-3
n=-3
hope this helps :)
