5c+4 = 2 (c – 5)
What is the solution?

Answer:

I think they are both wrong

The correct way to solve it is this.

Step-by-step explanation:

Step 1: Subtract 4 from both sides.

[tex]-6x+4-4=-20-4[/tex]

[tex]-6x=-24[/tex]

Step 2: Divide both sides by -6.

[tex]x=4[/tex]

Answer:

x=4

This is a problem of equation part of Algebra.

Some important Algebra formulas.

(a + b)² = a² + 2ab + b²

(a − b)² = a² − 2ab − b²

(a + b)³ = a³ + 3a²b + 3ab² + b³

(a - b)³ = a³ - 3a²b + 3ab² - b³

a³ + b³ = (a + b)³ − 3ab(a + b)

a³ - b³ = (a -b)³ + 3ab(a - b)

a² − b² = (a + b)(a − b)

a² + b² = (a + b)² − 2ab

a² + b² = (a − b)² + 2ab

a³ − b³ = (a − b)(a² + ab + b²)

a³ + b³ = (a + b)(a² − ab + b²)

Here given, equation is [tex] - 6x + 4 = - 20[/tex]

Now,

-6x + 4 = -20

First we are separating variable and constant part.

So first we subtracting 4 from (-20) and get

[tex] - 6x = - 20 - 4[/tex]

or,[tex] - 6x = - 24[/tex]

Now (-24) is dividing by (-6) and get,

[tex]x = \frac{ - 24}{ - 6} \\ x = 4[/tex]

So, value of x is 4.

Answer:

  11.4 years

Step-by-step explanation:

We assume you want to know the time it takes for Lucy's investment of $1200 to have a value of $6400. The compound interest formula is good for finding that.

  FV = P(1 +r/n)^(nt)

for principal P invested at rate r per year for t years, compounded n times per year. We want to find t such that ...

  6400 = 1200(1 +0.15/4)^(4t)

  16/3 = 1.0375^(4t) . . . . divide by 1200

  log(16/3) = 4t·log(1.0375) . . . . take logarithms

  t = log(16/3)/(4·log(1.0375)) ≈ 11.4

It will take about 11.4 years for Lucy's investment value to be $6400.

Answer:

Yes, this is a right triangle.

Step-by-step explanation:

The Pythagorean Theorem states that if the sum of the squares of the two small sides of a triangle add up to the square of the longest side, then the triangle is a right triangle: a² + b² = c², where a and b are the smallest sides (called legs) and c is the longest side (called the hypotenuse).

Here, the two smallest sides are 10 and 49.5, so let's square them, add them up, and see if they add up to 50.5²:

10² = 100

49.5² = 2450.25

100 + 2450.25 = 2550.25

50.5² = 2550.25

Since 10² + 49.5² equals 50.5², we know that this is a right triangle.

Thus, yes, this is a right triangle.

Answer:

5/33

Step-by-step explanation:

five apples and seven peaches = 12 total

P( apple) = number of apples / total

               = 5/12

No replacement since you ate it

four apples and seven peaches = 11 total

P( peach) = number of peach / total

               = 4/11

Answer:

y = 5x + 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 5x + 9 ← is in slope- intercept form

with slope m = 5

Parallel lines have equal slopes, thus

y = 5x + c ← is the partial equation

To find c substitute (- 2, - 3) into the partial equation

- 3 = - 10 + c ⇒ c = - 3 + 10 = 7

y = 5x + 7 ← equation of parallel line

A,D,F

A is in Quadrant I.

D is in Quadrant III.

F is on the x-axis.

Step-by-step explanation:

got this right..... I did this like 3 months ago so I just answered this

hope this helps:)

The statements A is in Quadrant I is true, D is in Quadrant III is true and F is on the x axis is true.

Coordinate geometry is defined as the study of geometry using the coordinate points.

On a coordinate plane, point A is (2, 3),

point B is (3, 2),

point C is (negative 2, 2),

point D is (negative 3, negative 3),

point E is (0, 3),

point F is (2, 0), and

point G is (0, 0).

A coordinate geometry has 4 quadrants, in the first Quadrant the x and y axis values are positive.

In second quadrant the coordinates are (-x, y)

In third quadrant the coordinates are (-x, -y)

In fourth quadrant the coordinates are (x, y)

A is in Quadrant I is true

D is in Quadrant III is true

F is on the x axis is true.

Hence, the statements A is in Quadrant I is true, D is in Quadrant III is true and F is on the x axis is true.

Answer:

x = [tex]\frac{6}{4+a-2b}[/tex]

Step-by-step explanation:

Given

4x + ax = 2(bx + 3) ← distribute parenthesis

4x + ax = 2bx + 6 ( subtract 2bx from both sides )

4x + ax - 2bx = 6 ← factor out x from each term on the left side

x(4 + a - 2b) = 6 ← divide both sides by (4 + a - 2b)

x = [tex]\frac{6}{4+a-2b}[/tex]

Answer: 102.9m

Step-by-step explanation: From A to C you can go from the diagonal path and then go around the circular path and then continue the diagonal path. In order to work out the length of the diagonal, you can simply use pythagoras as the triangle is right angled. So to find the length of the whole diameter, you should do 50 squared plus 80 squared and then square root the answer to get 94.34. But then you have to subtract the part of the diagonal line which the circle takes up, so we already know that the diameter of the circle is 15m so we simply do 94.34-15 to get 79.34. This means that we have found the length of the two diagonals, but now we need to find the length of half the circumference of the circle so that the path is complete and to find half the circumference, we'd do Pi multiplied by the diameter (15) and then divide the answer by 2 (because we are only finding the circumference for half of the circle as we have you go around the circle), leaving us with the answer of 23.56. We then add this to the 79.34 to get the answer of 102.9m. We know this is the shortest route as going along the edges of the rectangle would be 130m which is longer than 102.9m.

Answer:

x = 4.3

Step-by-step explanation:

Lets solve!

1.2(x) = 5.16

Divide both sides by 1.2 to get

x = 4.3

Answer:x=4.3

Step-by-step explanation:

Step 1: Divide both sides by 1.2

1.2x/1.2=5.16/1.2

X=4.3

Let the first number = x

The second number would be x +1

3rd number = x +2

4th number = x +3

5th number = x+4

6th number = x+5

7th number = x +6

8th number = x +7

9th number = x+8

The sum is 279

Combine like terms in the 9 numbers to get: 9x + 36 = 279

Solve for x:

9x + 36 = 279

Subtract 36 from both sides:

9x = 243

Divide both sides by 9:

x =27

The first number is 27

The last number would be 27 + 8 = 35

The sum of the first and last would be 27 + 35 = 63
