Answer:
1, 4 or 7
Step-by-step explanation:
The divisibility rule/shortcut for 3 is that the sum of its digits is divisible by 3. So, you currently have 29 (7+1+7+6+2+6+0), and you have to make that number divisible by 3.
adding 1 gets you 30, which we know is divisible by 3.
then, instead of trying every digit, we can note that
30 , 33 , 36 , 39 ....
are divisible by 3.
But the most we can add to the sum of 29 is 9 (because that is the highest digit possible)--so numbers above 38 are irrelevant
so, we want to find out if we can make 29 into 30, 33, or 36
adding 1 to 29 = 30
adding 4 to 29 = 33
adding 7 to 29 = 36
So, by making the first digit 1 , 4 , or 7, you make the number divisible by 3 (making the sentence true)
Answer:
x=-2, y=-10
Step-by-step explanation:
Since both equations are equal to y, we can set them equal to each other and solve
x-8=5x
Subtract x from both sides
-8=4x
Divide both sides by 4
x=-2
Next, we need to find a y
Substitute -2 in for x in one of the equations and solve
y=5x
y=5*-2
y=-10
x=-2, y=-10
This should be anegative decrease
Answer:
normally i would but i think it will be better if you did it yourself. i mean you can always use a calculator
explanation:
I hope this helps you!
I think its about 62 hours because you multiply the 185 days by 20 minutes and get 3,700 so you divide that by 60 and get 61.6666667. so the answer is 62 hours?
