Answer:

I hope it helpss!!!!!!! :)

Step-by-step explanation:

Given

-30 = - 0.4 k

30 = 0.4k

k = 30 / 0.4

k = 75

hope it helps :)

Answer:

Simplifying

-38 = -0.4k

Solving

-38 = -0.4k

Solving for variable 'k'.

Move all terms containing k to the left, all other terms to the right.

Add '0.4k' to each side of the equation.

-38 + 0.4k = -0.4k + 0.4k

Combine like terms: -0.4k + 0.4k = 0.0

-38 + 0.4k = 0.0

Add '38' to each side of the equation.

-38 + 38 + 0.4k = 0.0 + 38

Combine like terms: -38 + 38 = 0

0 + 0.4k = 0.0 + 38

0.4k = 0.0 + 38

Combine like terms: 0.0 + 38 = 38

0.4k = 38

Divide each side by '0.4'.

k = 95

Simplifying

k = 95

Answer:

x = √6/2

Step-by-step explanation:

Side a = 1.73205 --> √3

Side b = 1.22474 --> √6/2

Side c = 1.22474 --> √6/2

Step-by-step explanation:

1) first eliminate constant(number without variable) you eliminate constant by doing the inverse operation(if constant is being added, then subtract)(if constant is being subtracted, then add it)

ex: if   x+9=32

subtract 9 from both sides to get rid of it

x=23

2) if there is another constant but this constant is being multiplied/divided then do the opposite operation to remove it

you could multiply by 3 on both sides:

x+9=69

x=60

Step-by-step explanation:

Answer:

x= -6

Step-by-step explanation:

5.(x+3) = 2x-3

5x+15=2x-3

5x-2x+15=-3

5x-2x=-3-15

3x=-3-15

3x=-18

x=-6

Step-by-step explanation:

5(X+3) =2X_3

Expand the brackets

5X + 15 = 2X _ 3

CLT(Collect like terms)

5X_2X= _3 _ 15

3X = _ 18

DBS( Divide both sides) by 3

3X/ 3 = _18 / 3

X = _9

Answer:

12

Step-by-step explanation:

add the numbers to get the total then divide the total by the amount of columns/numbers.

12 + 12 + 18 + 6 = 48

48 / 4 = 12

Answer:

12 + 12 + 18 + 6 = 48

48/4 = 12

Answer:

[tex]y=\dfrac{3}{4}x+15[/tex]

Step-by-step explanation:

Given that,

A line goes through the point (-8,9), and has a slope of 3/4.

We need to express in the form of Ax+B for this line.

We have, m = 3/4

So,

[tex]y=\dfrac{3}{4}x+B[/tex]

Put y = 9 and x = -8 in the above equation.

[tex]9=\dfrac{3}{4}(-8)+B\\\\9=-6+B\\\\9+6=B\\\\B=15[/tex]

So,

[tex]y=\dfrac{3}{4}x+15[/tex]

It is the required equation of the line.

Answer:

2t+5

Step-by-step explanation:

Answer:

(1,-4)

Step-by-step explanation:

First manipulate the second equation so that y is by itself

x-y=5

-y=-x+5

y=x-5

then substitute that y in for the y in the above equation and solve for y

y=-2x-2

x-5=-2x-2

3x-5=-2

3x=3

x=1

Now that you have the x-coordinate, find the y-coordinate by plugging in the x-value in either of the equations

y=-2x-2

y=-2(1)-2

y=-2-2

y=-4

I see that you're using deltamath, and I think for the graph questions, you could first place a point for the y-intercept of one of the equations, and then place another point that is on the graph of the equation. Once you plotted both lines, just see the point where they meet and that is where the two systems of equations meet.

Answer:

the answer is 5x + 2. I hoped that worked

Answer:

Perimeter of triangle = 14.82 approx.

Step-by-step explanation:

Given:

D(5, 6)

E (10, 9)

F(7, 11)

Find:

Perimeter of triangle

Computation:

Distance = √(x1-x2)² + (y1-y2)²

Perimeter of triangle = DE + EF + FD

Perimeter of triangle = √(5-10)² + (6-9)² + √(10-7)² + (9-11)² + √(7-5)² + (11-6)²

Perimeter of triangle = √25 + 9 + √9 + 4 + √4 + 25

Perimeter of triangle = √34 + √13 + √29

Perimeter of triangle = 5.83 + 3.6 + 5.3851

Perimeter of triangle = 14.8151

Perimeter of triangle = 14.82 approx.

Answer:

(6-2) (3/4-3/20)

4 ((3×20-3×4)/80)

4 48/80

4 3/5

Answer:

1.6

Step-by-step explanation:

7 and three tenths = 7 + 3/10 = 7.3

5 and seven tenths = 5 + 7/10 = 5.7

7.3-5.7 = 1.6 or can be written as 1 and six tenths, or 1 and three fifths.

Answer:

I think the answered is x = 16 hope I right

Answer:

X = 16

Step-by-step explanation:

2.5x+10 = 50

distribute the ten to the other side by substracting

2.5x = 50-10

2.5x = 40

Now divide 2.5 on both sides

2.5x/2.5 = 40/2.5

x = 16

Answer:

Y=4

Step-by-step explanation:

8*0+4=4

Answer:

[tex]40*a*b[/tex]

Step-by-step explanation:

40ab is 40 multiplied by a multiplied by b

To solve for X in this equation, you would subtract both sides by 14 because our goal is to get X on its own. If we write it out, we see that

X + 14 - 14 = 56 - 14

X=42

Because we have a positive 14, a negative 14 will average out to be 0, but what you do to one side, you must do to the other.

Answer:

[tex] {x}^{2} - 25[/tex]

Step-by-step explanation:

[tex](x + 5)(x – 5) \\ \\ = {(x)}^{2} - {(5)}^{2} \\ \\ = {x}^{2} - 25[/tex]

Answer:

x²-25

Step-by-step explanation:

To do a sum like this, break up the first bracket and multiply by the second (terms from the first bracket is in bold in first few steps for clarity):

(x + 5)(x – 5)

x(x-5)+5(x-5)

x²-5x+5x-25

x²-25

Step-by-step explanation:

[tex]4 \\ {x}^{2} = {16}^{2} + {14}^{2} \\ {x}^{2} = 256 + 196 \\ {x}^{2} = 452 = 2 \sqrt{113} = 21.26[/tex]

[tex]5 \\ {x}^{2} = {8}^{2} + {15}^{2} \\ {x}^{2} = 64 + 225 \\ {x}^{2} = 289 \\ x = 17[/tex]

Step-by-step explanation:

Answer:

Yes

Step-by-step explanation:

In the first equation, sub in (-3x/2) for y:

3x+4y=12

3x+4(-3x/2)=12

3x-(12x/2)=12

3x-6x=12

-3x=12

x=-4

y=-3x/2

y=-3(-4)/2

y=12/2

y=6

Since x=-4 and y=6, (-4,6) is a solution.
