Round off 3. 55 to one significant figure
Anika [276]

Answer:

3.6

Step-by-step explanation:

We must first clarify how a number is rounded.

To round a number to unity we have to look at the first number after the comma.

If this number is less than 5 (1, 2, 3, 4) we should not do anything, but if that number is 5 or greater (5, 6, 7, 8, 9) we must add a unit to the number.

That is to say:

<5 do nothing

=> 5 round to the next number (+1)

So in the case of 3.55 it would be.

3.55 = 3.6

Explain how you would graph 3x+9y= -18 without converting to slope-intercept form​
Zolol [24]

Answer:

you would solve using x and y intercepts.

Step-by-step explanation:

for the X intercept, Y=0

3x=-18. you divide by three on both sides

x=-6. (-6,0)

the for the y intercept, X=0

+9y=-18. you divide 9 on both sides.

y=-2. (0,-2)

then you graph both and connect the points on the x and y axis.

galben [10]

Answer:

I think it goes like this : 20:4=5 so there's five monsters in the room

Step-by-step explanation:

if that's the case of this question it should go like this:

9(rooms)×5(monsters per room)= 45 monsters

30(monsters):5(monsters per room)=6 rooms

13(rooms)×5(monsters per room)=65 monsters

35(monsters):5(monsters per room)=7 rooms

I hope you do well in your assignment.

I hope I helped at least a little!
