Round 0.97 to the nearest tenth

Mathematics

0.97 the tenth digit is the first digit after the decimal point.

That is the 9.

The digit after the 9 is 7, and this is more than 5, so we add an extra 1 to the 9, and it becomes 10.

The 1 spills over to the right sides of the decimal point.

0.97 ≈ 1.0 to the nearest tenth.

The tens column is the one directly to the right of the decimal, so you need to get rid of the seven. Since the 7 is closer to ten than it is to zero (it's bigger than 5), you will round up. When you round up, you add 1 to the number on the left, the 9. So it will become 10, or 1.0

Solve the system of linear equations using multiplication.
Anna71 [15]

Answer:

(8,-1)

Step-by-step explanation:

The given system is:

3x+3y=21

6x+12y=36

Since I prefer to use smaller numbers I'm going to divide both sides of the first equation by 3 and both sides of the equation equation by 6.

This gives me the system:

x+y=7

x+2y=6

We could solve the first equation for x and replace the second x with that.

Let's do that.

x+y=7

Subtract y on both sides:

x=7-y

So we are replacing the second x in the second equation with (7-y) which gives us:

(7-y)+2y=6

7-y+2y=6

7+y=6

y=6-7

y=-1

Now recall the first equation we arranged so that x was the subject. I'm referring to x=7-y.

We can now find x given that y=-1 using the equation x=7-y.

Let's do that.

x=7-y with y=-1:

x=7-(-1)

x=7+1

x=8

So the solution is (8,-1).

We can check this point by plugging it into both equations.

If both equations render true for that point, then we have verify the solution.

Let's try it.

3x+3y=21 with (x,y)=(8,-1):

3(8)+3(-1)=21

24+(-3)=21

21=21 is a true equation so the "solution" looks promising still.

6x+12y=36 with (x,y)=(8,-1):

6(8)+12(-1)=36

48+(-12)=36

36=36 is also true so the solution has been verified since both equations render true for that point.
