18/19 as a decimal rounded to the nearest hundredth

Answer:

x=4

Step-by-step explanation:

2x+3x+1=21

(2x+3x)+(1)=21

5x+1=21

5x+1=21

Step 2: Subtract 1 from both sides.

5x+1−1=21−1

5x=20

Step 3: Divide both sides by 5.

Answer:

x=4

Step-by-step explanation:

2x+3x+1=21

Simplify both sides of the equation.

2x+3x+1=21

(2x+3x)+(1)=21(Combine Like Terms)

5x+1=21

5x+1=21

Subtract 1 from both sides.

5x+1−1=21−1

5x=20

Divide both sides by 5.

5x /5 = 20 /5

x=4

Answer:

i cant choose any that applies to this question because there is no picture added to it and there are no choices to choose from. If i were to solve it though, it would be; yes, he will save enough money for his vacation.

Step-by-step explanation:

I know he would have enough--and in this case more than enough, because since he's planning to save $30 for a whole year just for $50, when he could simply make $60--which is in fact more than needed for his goal-- in just 2 months. If he were to stick with his plan though, he'd make $360. I got that by multiplying 30 by 12.

Answer:

260 miles

Step-by-step explanation:

Given that:

Distance covered in 7 hours = 455 miles

Number of miles train will travel in 4 hours

Average travel speed per hour :

Distance traveled / time taken

455 miles / 7 hours

= 65 miles per hour

Number of miles traveled in 4 hours :

Average Speed per hour * time

(65 * 4) = 260 miles

Answer:

25%, since 1/4=0.25 and 0.25*100 is 25%

Hope it helps!

Answer:

Step-by-step explanation:

Given data:

The given fraction is [tex]\frac{1}{4}[/tex]

The given fraction can be written as,

[tex]\frac{1}{4}=0.25\\=\frac{25}{100} \\=25 percentage[/tex]

Thus , the given fraction is 25%.

Answer:

A: 11 cents per ounce

B: 11.5 cents per ounce

C: 14 cents per ounce

Bag A would be the best buy

Answer: 14

Step-by-step explanation: The perimeter is all of the side added together. When finding the perimeter of a rectangle the opposing sides have the same value. So the equation would be 2(12) + 2(a) = 52. 12 x 2 is 24. 52- 24 is 28 and youre left with 28 = 2(a). You divide each side by 2 and get 14 = a

Answer:

Answer:

B. [tex]-(3x+1) (x+5)[/tex]

Step-by-step explanation

factored the equation to solve. Hope this helps!

Answer:

2.0 , 2/1.

1.35 , 1  7/20.

1.52, 1 13/25

0.0003, 3/10000

0.0045, 9/2000

Step-by-step explanation:

1.35 =  1 35/100 = 1 7/20

1.52 = 1 52/100 = 1 13/25

0.0045 = 45/10000 = 1 9/2000.

Step-by-step explanation:

Answer:

The equation of the straight line is  x - 2y +6 =0

Step-by-step explanation:

Explanation:-

Given a point ( 2, 4) and slope m =  [tex]\frac{1}{2}[/tex]

The equation of the straight line passing through the point and having slope 'm'

          y - y₁ = m ( x - x₁)

           y - 4 = [tex]\frac{1}{2}[/tex] ( x - 2)

          2( y -4) = ( x-2)

          2 y - 8 = x -2

          x - 2 y - 2 + 8 =0

          x - 2y + 6 =0

The equation of the straight line is  x - 2y +6 =0

The answer is:

y = 1/2x + 5

Work/explanation:

Since I have a point and the slope, I will write the equation in point slope form.

Point slope is

[tex]\sf{y-y_1=m(x-x_1)}[/tex]

where m = slope and (x₁, y₁) is a point on the line

Plug in the data

[tex]\sf{y-4=\dfrac{1}{2}(x-2)}[/tex]

Now let's simplify to slope intercept

                    [tex]\large\begin{gathered}\sf{y-4=\dfrac{1}{2}x+1}\\\sf{y=\dfrac{1}{2}x+1+4}\\\sf{y=\dfrac{1}{2}x+5}\end{gathered}[/tex]

Answer:

136

Step-by-step explanation:

triangles CAB and CED are similar, their sides are proportional

set up a proportion:

[tex]\frac{51}{144-x}[/tex] = [tex]\frac{3}{x}[/tex]

cross-multiply:  51x = 3(144 - x)

                         51x = 432 - 3x

                         54x = 432

                          x = 8

Plug in:

144 - 8 = 136

Answer:

y=3x+4

Step-by-step explanation:

First, you want to get the 'y' by itself.

5y=15x+20

Now, you want to divide everything by 5.

y=3x+4

I think the answer is A. 3.

B. no, to big a number

C. no, to small a number

D. no, again, too big a number.

Have a nice day and hope this helps!

An absolute value is the positive value of the number between the vertical lines.

If the number in between the vertical lines is negative, the absolute value become a positive.

 If the value in between the lines is already positive, it stays positive.

17. |-8| = 8

18. |13| = 13

19. |3 6/7| = 3 6/7

20. |-1.34| = 1.34

Answer:

17. 8

18.13

19. 3 6/7

20. 1.34

Step-by-step explanation:

The absolute value would just be the opposite of the original value.

Answer:

always true

Step-by-step explanation:

Given

2(x + 3) = 5x + 6 - 3x ← distribute left side

2x + 6 = 2x + 6

Since both sides are equal then any real value of x is a solution.

Thus the equation is always true
