Answer:
x= 24/19 or 1.263
Step-by-step explanation:
If you need an explanation lmk.
You can either graph the two lines on an online graphing website and find where they intersect.
If you aren't allowed to do so, just plug in one equation into the other.
y=3x+12, so plug in y into 2y= -x-11.
Then you get 2(3x+12)=-x-11.
Distribute to get 6x+24= -x-11
At this point I hope you can solve for x by yourself, but if you can't, here's how:
7x+24=-11
7x=-25
x=
To find y, plug in x into either equations: <span>2y= -x -11 and y=3x + 12.
</span>You get about -3.714
So coordinate of interesection=
, -3.714
well, 61.53 is really 10 + 10 + 10 + 10 + 10 + 10 + 1.53.
well, 1.53 doesn't really come nowhere near close to round up to 10, so it boils down to 0, so 61.53 will just be 10 + 10 + 10 + 10 + 10 + 10 + 0 or just 60 once rounded up, now, what's 15% of 60?
well, we can get the 15% of 61.53 by just (15/100) * 61.53
however, the exercise is asking on rounding it up to "tens" first
61.53 has "10" six times plus 1.53, the rounding happens with the "surplus"
in this case the surplus is 1.53.
now, for rounding anything the tipover point is at the half, for $10 the half is $5, so if the amount is $5 or more, rounds up to $10, if less than that goes to 0.
1.53 is nowhere near 5, which is the halfpoint or tipover point, because of that, it rounds up to 0, so 61.53 rounded up to "tens" only will be "six tens" only, or 60.

<span>Multiples
of 3 are {3, 6, 9, 12, 15, 18, 21, 24, 27, 30, …….} , these are all the
multiples of 3.
Now, we are looking a negative multiple of 3, which means, we need to a
negative value of 3 multiples.
=> -3 {-3, -6, -9, -12, -15, -18, -21, -24, -27, -30,…..} These are all the
negative multiple of 3 in set builder notation.
Notice, that the numbers are of divisible by 3. Any number that Is divisible by
3 is called multiple of 3.
