Answer:

  x = -20

Step-by-step explanation:

First, simplify the equation. Eliminate parentheses and combine terms.

  3(x -1) -8 = 4(1 +x) +5 . . . . . . . given

  3x -3 -8 = 4 +4x +5 . . . . . . . . eliminate parentheses (distributive property)

  3x -11 = 4x +9 . . . . . . . . . . . . combine like terms

We can put all the x-terms on the right by subtracting 3x from both sides.

  3x -11 -3x = 4x +9 -3x

  -11 = x +9

And we can get the x-term by itself by subtracting 9 from both sides.

  -11 -9 = x +9 -9

  -20 = x . . . . . . . . . . this is the solution

__

Check

3(-20 -1) -8 = 4(1 -20) +5

3(-21) -8 = 4(-19) +5

-63 -8 = -76 +5

-71 = -71 . . . . . . . . . true, the answer checks OK

Additional comment

We observe that the two x-terms are 3x and 4x. The smaller of these is 3x, so when we subtract that from 4x we will have a positive result. That is why we chose to subtract 3x, even though it leaves the x-term on the right side of the equation. We could have subtracted 4x to get -x -11 = 9. I find it easier not to make a mistake if the variable has a positive coefficient.

Answer:

ten thousands place

Step-by-step explanation:

10,000 × 10 = 100,000

6 3/4 per hour or, in an hour

2 1/4 miles in 3/4 of an hour

2 1/4 miles = 9/4 miles in 1/3 of hour

9/4 miles divided by 1/3 hr

9/4 ÷ 1/3

Remember: Keep, Change Flip

9/4 x 3/1 = 27/4

Simplify:

27/4 = 6 3/4

So,

6 3/4 in one hour

Answer:

The perimeter of a rectangle is the sum of all of it’s sides. Since a rectangle has 2 lengths of the same size and two widths of the same size, the perimeter is length + length + width + width, or 2(length) + 2(width), or, to make it shorter, 2l + 2w.

Since the length of the rectangle (l) in this scenario is really 4w, we can replace those, and get 2(4w) + 2w, and since we know the total is 50, we can say 2(4w) + 2w = 50.

Using the distributive property, we get 8w + 2w = 50, and 10w = 50, or w = 5. Since the length is 4w, the length is 4*5 = 20.

To find the area, you multiply length and width to get 5 * 20 = 100 sq meters.

Answer:

12/11

Step-by-step explanation:

11/11=1

1/11=1/11

11/11+1/11=12/11

[tex]1\frac{1}{11}[/tex]  rewritten as a single fraction is 12/11

[tex]1\frac{1}{11}[/tex] is a mixed fraction.

A fraction is a number that is made up of a numerator and a denominator.

A mixed fraction is made up of a whole number and a proper fraction. A proper fraction is a fraction that is made up of a numerator that is less than a denominator.

For example, [tex]\frac{1}{11}[/tex] is a proper fraction. The numerataor,1, is less than the denominator, 11.

We are to convert the mixed fraction to an improper fraction. An improper fraction is a fraction that its numerator is greater than the denominator.

In order to convert to an improper fraction, take these steps

Answer:

2√(17) or about 8.2462 units.

Step-by-step explanation:

We want to determine the distance between the two points (-10, -7) and (-8, 1).

We can use the distance formula. Recall that:

[tex]\displaystyle d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]

Substitute and evaluate:

[tex]\displaystyle \begin{aligned} d &= \sqrt{((-10)-(-8))^2 + ((-7) - (1))^2} \\ \\ &=\sqrt{(-2)^2+(-8)^2} \\ \\ &= \sqrt{(4) + (64)} \\ \\ &= \sqrt{68}\\ \\ &= 2\sqrt{17}\end{aligned}[/tex]

Hence, the distance between (-10, -7) and (-8, 1) is 2√(17) units or about 8.2462 units.

Answer:

Step-by-step explanation:

Keep in mind we read graphs from left to right just like how we read and write.

We can use those tips to solve the problem.

Option A:

4/5 is a positive slope so it will rise from left to right.

Option B:

No slope automatically means "undefined" so that falls in the definition of a vertical line.

Option C:

A slope of 0 is defined as a horizontal line.

Option D:

-4/5 is a negative slope so it will fall from left to right.

Answer:

10

Step-by-step explanation:

So you start with

0.10x+0.25(24-x)=4.50

First you do the parenthesis

.25x24 is 6.

So

.10x+6-.25x=4.5

Combine like terms

-.15x+6=4.5

Now isolate the x so you can find what x is

4.5-6

-.15x=-1.5

Then divide

-1.5/-.15

The two negatives make it positive

So 1.5/0.15

Comes to 10.

x=10

The 10 comes like this .15 is 15/100

Simplify that to 3/20

1.5 is 15/10

Simplify that to 3/2

Then divide those

3/2 ÷ 3/20

You cant divide fractions so flip the other side and multiply

3/2 × 20/3

60/6

10

Hope this helps

Answer:

x = 10

Step-by-step explanation:

[tex]0.10x + 0.25(24 - x) = 4.50[/tex]

[tex]0.1x + 6 - 0.25x = 4.5[/tex]

[tex] - 0.15x + 6 = 4.5[/tex]

[tex] - 0.15x = - 1.5[/tex]

[tex]x = 10[/tex]
