Answer:

18-ft.

Step-by-step explanation:

WHEW. Just buy it for 11.52. If you bought 18 yd of butcher paper from the 3 yd roll you would be spending almost 52 dollars!

Answer: 3-Yard roll or butcher paper

Step-by-step explanation:

3 Yards = 9 Feet. 3 yards is half of 18 feet. And the cost of 3 yards is only 2.88, And since it is half of the amount of 18 feet, we multiply by two. ($5.76). Meaning 3 Yards is better to buy.

Step-by-step explanation:

You multiply the two other sides by itself like 12x12=144 and do that for all the sides that you know then you add up all of the numbers you got from adding like 144 plus 64 equals 208 and then 208 is the hypotenuse.

Answer:

1.) 10

2.) 8

3.) 24

4.) 4

5.)39

6.) 45

7.) 15

8.) 6

Step-by-step explanation:

1.) 9+8= 17, 17-7=10

2.) 7-5=2, 2+6=8

3.) 4(-1)= -4, -6(-4)=24

4.)8/4=2, 2(2)=4

5.) 6+7=13, 3(13)=39

6.) 10-1=9, 5(9)=45

7.) 72/9=8, 8+7=15

8.) 4+4=8, 48/8=6

Hope this helps.

Step-by-step explanation:

9+8-7=(9+8)-7=17-7=10

7-5+6=(7-5)+6=2+6=8

-6*4(-1)=-6*(-4)=24

8/4*2=2*2=4

3(6+7)=3*13=39

5(10-1)=5*9=45

72/9+7=8+7=15

48/(4+4)=48/8=6

Answer:

0.64

Step-by-step explanation:

Find the number in the hundredth place  4  and look one place to the right for the rounding digit  1 . Round up if this number is greater than or equal to  5  and round down if it is less than  5 .

Answer:

7

Step-by-step explanation:

Let’s think about this like a number line.

If we have a number line with the ends of F and H, and G is somewhere in between, it would look something like this.

F———-G———H

We know that FH = 19 and that FG is 12.

This means that GH will be the FH - FG

[tex]19 - 12 = 7[/tex]

So FG is 7.

Answer:

  the comparison was not reversed when dividing by -9

Step-by-step explanation:

It looks like Eduardo's steps might be ...

  −5(x + 4) + 21 ≥ −3 + 4(x − 8)

  −5x − 20 + 21 ≥ −3 + 4x − 32  . . . .  correct

  −5x + 1 ≥ 4x − 35  . . . .  correct

  −9x ≥ −36  . . . .  correct

  x ≥ 4  . . . . .  should be x ≤ 4

Dividing by -9 should reverse the comparison symbol.

Answer:

should be x ≤ 4

Step-by-step explanation:

3n-7n-n = 15

5n = 15

n = 15 ÷ 5

n = 3

Step-by-step explanation:

3n−15=7n+n

3n-15=8n

3n-15+15=8n+15

3n=8n+15

3n-8n=8n+15-8n

-5n=15

answer:

n= -3

Answer:

5 because -20 divided by -4 is 5

Step-by-step explanation:

Step-by-step explanation:

(x^3 - 9x) divided by (x^3 + x^2 - 6x)

= x(x^2 - 9) divided by x(x^2 + x - 6)

= x(x + 3)(x - 3) divided by x(x - 2)(x + 3)

= (x - 3)/(x - 2).

Answer:

Y=-16

Step-by-step explanation:

-3(6)+3

-18+2

y=-16

Answer:

-16

Step-by-step explanation:

We can evaluate y = -3x + 2 for x = 6.  Substituting 6 for x in y = -3x +2, we get:

y = -3(6) + 2 = -18 + 2 = -16

The equation  y = -3x + 2 has already been "solved" for y.  At this point you are evaluating this equation  at x = 6.

Answer:

3.6 hours

Step-by-step explanation:

One person can complete a typing project in 6 hours,

Hence, in 1 hour, 1/6 of the project is completed by person A

Another can complete the same project in 9 hours.

Hence, in 1 hour, 1/9 of the project is completed by person B

Let the number of hours of completing the project be represented by 1

Hence,

x/6 + x/9 = 1

We find the L.C.M

9x + 6x/54= 1

15x/54 = 1

Cross Multiply

15x = 54

x = 54/15

x = 3.6 hours.

Therefore, both people can complete the project in 3.6 hours.

Answer:

The ratio for AD:DC is 2:3

Step-by-step explanation:

The given information are;

The ratio by which point B splits AC as AB:BC = 2:1

The ratio by which point D splits AB as AD:DB = 3:2

Therefore, we have;

The fraction of AC that is equal to AB is given as follows;

AB = 2/(2 + 1) × AC = 2/3 × AC

AB = 2/3 × AC

Similarly

BC = 1/3 × AC

Also the fraction of AB that is equal to AD is given as follows;

AD = 3/(3 + 2) × AB = 3/5 × AB

AD = 3/5 × AB

Therefore, the fraction of AC that is equal to AD is given as follows;

AD = 3/5 × AB = 3/5 × 2/3 × AC = 2/5 × AC

Therefore, DC = (1 - 2/5) × AC = 3/5 × AC

Which gives the ration of AD to DC or AD:DC as being;

AD:DC = 2/5 × AC : 3/5 × AC  = 2/5:3/5 = 2:3

The ratio for AD:DC = 2:3.

Answer:

Terminating decimal.

Step-by-step explanation:

We need to find, if a fraction converts into a decimal that eventually stops what do we call it.

If a fraction converts into a decimal that eventually stops is called terminating decimals.

For example : 0.1, 2.45, 3.4657 etc.

If a fraction converts into a decimal that is repeating and do not stops is called non-terminating recurring decimals.

For example : 0.333..., 2.3454545... etc.

If a fraction converts into a decimal that is not repeating and do not stops is called non-terminating, non-recurring decimals.

For example : 0.2345172..., 2.34093795... etc.

Therefore, required answer is terminating decimal.

Answer:

The answer is

Step-by-step explanation:

- 2x + 4 > - 4x + 8

Add 4x to both sides of the inequality

That's

- 2x + 4x + 4 > - 4x + 4x + 8

2x + 4 > 8

Subtract 4 from both sides

That's

2x + 4 - 4 > 8 - 4

2x > 4

Divide both sides by 2

That's

[tex] \frac{2x}{2} > \frac{4}{2} [/tex]

We have the final answer as
