Answer:

9, -8, 15

Step-by-step explanation:

Equation 1

[tex]5(x+7)-3(x-4)=7x+2 \\ \\ 5x+35-3x+12=7x+2 \\ \\ 2x+47=7x+2 \\ \\ 47=5x+2 \\ \\ 45=5x \\ \\ x=9[/tex]

Equation 2

[tex]4(3x+5)-3=9x-7 \\ \\ 12x+20-3=9x-7 \\ \\ 12x+17=9x-7 \\ \\ 3x+17=-7 \\ \\ 3x=-24 \\ \\ x=-8[/tex]

Equation 3

[tex]\frac{1}{3}(5x-9)=2\left(\frac{1}{3}x+6 \right) \\ \\ 5x-9=2(x+18) \\ \\ 5x-9=2x+36 \\ \\ 3x-9=36 \\ \\ 3x=45 \\ \\ x=15[/tex]

Answer:

x = 25

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180

2x + 3x + 55 = 180, that is

5x + 55 = 180 ( subtract 55 from both sides )

5x = 125 ( divide both sides by 5 )

x = 25

Time in hours is directly proportional to the number of newspapers.

3 hours = 450 newspapers

=> 4 hours = 450 * (4/3) = 600 newspapers.

Hence Joy can deliver 600 newspapers in 4 hours.

Answer:

y= 45

x=9

Step-by-step explanation:

plug 5x into y since y=5x:

5x=4x+9

-4. -4

x=9

5(9)=45

Answer:

x=9 y=45

Step-by-step explanation:

y=4x + 9.......(1)

y= 5x.........(2)

Substitute 5x for y in equation 1.

5x= 4x + 9

5x - 4x = 9 (Collect like terms 5 and 4 have x in common if +4 crossover it changes to -4)

x = 9

substitute 9 for x in equation 2.

y = 5(9)

y = 5 x 9(multiplication)

y = 45

Answer:

  a6 = -196,608

Step-by-step explanation:

The general term of a geometric sequence with first term a1 and common ratio r is given by ...

  an = a1·r^(n-1)

For a1 = 6, r = -8, and n = 6, we find the 6th term to be ...

  a6 = 6·(-8)^(6-1)

  a6 = -196,608

Step-by-step explanation:

Step-by-step explanation:

Soln

given,

from the figure

coordinate of B is (5,3),

A(7,0) and C(0,4)

A. solution

let, M(x,y) be the mid point of AB

A(7,0) = (x1,y1)

B(5,3) = (x2,y2)

we know

x = (x2+x1)/2

or, x = (5+7)/2

or, x = 12/2

or, x = 6

and for y

y = (y2+y1)/2

or, y = (3+0)/2

or, y = 3/2

therefore M(x,y) = (6,3/2)

B. solution

let,

C(0,4) = (x1,y1)

B(5,3) = (x2,y2)

equation of line is ;

(y - y1)/(x - x1) = (y2 - y1)/(x2 - x1)

or, (y - 4)/(x -0) = (3 - 4)/(5 - 0)

or, (y - 4)/(x - 0) = -1 / 5

by cross multiply

or, 5×(y - 4) = -1×(x)

or, 5y - 20 = -x

or, x + 5y = 20 is the required equation.

Answer and Step-by-step explanation:

To find the surface area, all you have to do is find the area of each face of the prism, and then add them all together.

15 x 20 = 300

(15 x 8)/2 = 60

(15 x 8)/2 = 60

(There are two triangles)

8 x 20 = 160

20 x 17 = 340

Now, add them all together.

300 + 60 + 60 + 160 + 340 = 920

The surface area of the prism is 920 [tex]units^{2}[/tex]

Answer:

We are given

We are also given  and , which allows us to rewrite the equation as

(I substituted every "b" with "a" and every "c" with "9").

The solutions to this quadratic equation are -25 and 7. We discard -25 because a side with negative length would make no sense.

The required measure of side a of the rectangular prism is a = 9.3 meters.

The surface area of any shape is the area of the shape that is faced or the Surface area is the amount of area covering the exterior of a 3D shape.

Here,
SA = 2ab + 2bc + 2ac
434 = 2a² + 14a + 14a
434 = 2a² + 28a
2a² + 28a - 434 = 0
a² + 14a - 217 = 0
a² + 14a + 49 - 49 - 217 = 0
(a + 7)² = 266
a = 9.3 or a = -23.3

Since the negative measure of length can be neglected.
a = 9.3 = b

Thus, the required measure of side a of the rectangular prism is a = 9.3 meters.

Answer: The mass of the sun is 3.51 x 10^3 times greater.

Step-by-step explanation:

X= Mass of Sun/ Mass of Saturn

X= 1.998 x 10^30 / 5.69 x 10^26

1.998/ 5.69 = .351

10^30 / 10^26 = 10^4

You want to move the decimal a value so you would subtract 1 from 4

3.51 x 10^3

The mass of the Sun is 3.511 × 10³ (in scientific notation) times more than the mass of Saturn.

The division means the separation of something into different parts, sharing of something among different people, places, etc.

The sun’s mass is [tex]1.998 * 10^{30}[/tex] kg.

Saturn's mass is [tex]5.69 * 10^{26}[/tex] kg.

Let the mass of the Sun be X times more than the mass of the Saturn mass.

The equation that can be written as

1.998 × 10³⁰ = X × 5.69 × 10²⁶

On simplifying, the value f X will be

[tex]\rm X = \dfrac{1.998 * 10^{30}}{5.69*10^{26}}\\\\X = 3511.42 \\\\X = 3.511 * 10^3[/tex]

The mass of the Sun is 3.511 × 10³ (in scientific notation) times more than the mass of Saturn.

Answer:

y = 9.5

Step-by-step explanation:

Express the ratios in fractional form, that is

[tex]\frac{1.5}{4}[/tex] = [tex]\frac{9}{2y+5}[/tex] ( cross- multiply )

1.5(2y + 5) = 36 ( divide both sides by 1.5 )

2y + 5 = 24 ( subtract 5 from both sides )

2y = 19 ( divide both sides by 2 )

y = [tex]\frac{19}{2}[/tex] = 9.5
