No. 26,341 is not evenly divisible by 3 .
Here's the trick you can use to decide this
just by looking at a big number:
==> If a number is divisible by 3, then the
sum of its digits is divisible by 3.
I've never taken the trouble to figure out why this works,
but it does work. I didn't make it up. It's widely known.
So let's look at 26,341 .
The sum of the digits is (2 + 6 + 3 + 4 + 1) = 16 .
16 is not divisible by 3 , so 26,341 is not divisible by 3 .
Is that cool or what !
Answer:
1/4x (8 x - 15)
Step-by-step explanation:
write the division as a fraction
1/2x + 3/2x (x - 5 ÷ 2)
factor out 1/2 from the expression.
1/2x(x + 3(x - 5 ÷ 2))
divide the numbers.
1/2x(x + 3(x - 2.5))
distribute 3 through the parentheses.
1/2x(x + 3x - 7.5)
collect like terms.
1/2x(4x - 7.5)
1/2x(4x - 15/2)
factor out 1/2 from the expression.
1/2 x 1/2 x (8 x - 15)
multiply the fractions
= 1/4 x (8x - 15)
or alternative form
= 0.25(8x - 15)
Answer: point, line, and plane.
Step-by-step explanation:
N=(-1,-4)
hmm, a 270 counterclockwise rotation is the same as a 90 degree clockwise
so that would become (-4,1)
N'=(-4,1)
