Answer:

Step-by-step explanation:

1) So -8+2v<2, 2v<10, v<5. That means that at "5" on the axis, you'll draw a circle that's <em>not</em> filled in (because it's <5, not \leq5) and then draw a box-y thing to the left. Sorry, can't really describe it, but if you look at the picture attached, you'll understand

2) -12m-8\leq-5m-7m, so -12m-8\leq-12m, -8\leq0. This one doesn't have a variable... so you can't really graph it?

If 8 pigs can fit in a pen, how many pens are necessary to make sure 71 pigs are all in a pen?
Ulleksa [173]

Answer:

9

Step-by-step explanation:

Each pen can only hold 8 pigs, and pens cannot be split up into fractions.

Divide. 71 / 8 = 8.875

There is no 7/8 of a pen, so you must round up.

8.875 → 9.

Four times the sum of half a number and 6 is 48
katrin [286]

Answer:

<h3>The number is 12</h3>

Step-by-step explanation:

Let the number be x

Half a number is written as 1/2x

So we have

Four times the sum of half a number and 6 is 48 is written as

4( \frac{1}{2} x + 6) = 48 \\ 2x + 24 = 48 \\ 2x = 48 - 24 \\ 2x = 24

Divide both sides by 2

That's

\frac{2x}{2}  =  \frac{24}{2}

We have the final answer as

<h3>x = 12</h3>

Hope this helps you
