Answer:

x=30

Step-by-step explanation:

8x - 3(2x-4) = 3(x-6)

first let's get rid of the brackets:

8x- 3·2x + 3·4 = 3x - 3·6

8x - 6x + 12 = 3x - 18

now group all the x terms and number terms

8x - 6x - 3x = -18 - 12

-x = -30

x = 30

Answer:4(x - 1) - x = 3(x + 5) - 11

Step-by-step explanation:

Lily's work:

4(x – 1) – x = 3(x + 5) – 11

4x – 4 – x = 3x + 15 – 11

3x – 4 = 3x + 4

Her partial solution, 3x - 4 = 3x + 4, can be interpreted as a FALSE statement because 3x - 4 does NOT equal 3x + 4.

Since it is a false statement, the equation has no solution.

The number of the solution will be infinity. Then the correct option is D.

The solution of the equation means the value of the unknown or variable.

The equation is given below.

4(x – 1) – x = 3(x + 5) – 11

Simplify the equation, we have

4x – 4 – x = 3x + 15 – 11

3x - 3x = 8

The variable x is eliminated.

Then the number of the solution will be infinity.

Then the correct option is D.

Step-by-step explanation:

I think.

Jesse Owen speed is 9.71 meters per seconds.

Speed is a scalar quantity that refers to "how fast an object is moving.

In other words, speed is the distance travelled per unit of time.

Therefore, it can be represented mathematically as follows:

speed = distance / time

Jesse Owen covers 100 meters dash for 10.3 seconds. Therefore, the speed he used for the race can be calculated as follows:

speed = distance / time

distance = 100 meters

time = 10.3 seconds

Hence,

speed = 100 / 10.3

speed = 9.70873786408

speed = 9.71 meters per seconds

Therefore, Jesse Owen speed is 9.71 meters per seconds.

Answer:

y = 6

Step-by-step explanation:

(7y-8y)2+14=2

First, simplify the left side

7y - 8y = -y

2*-y = -2y

Now solve the equation

-2y + 14 = 2

Subtract 14 from both sides

-2y = -12

Take away the negative signs since both sides are negative

2y = 12

Divide both sides by 2

y = 6

(If the variable was x instead of y the variable would still equal 6)

Answer:

x = 6, y = 5

Step-by-step explanation:

Solve the following system:

{5 y - 6 x = -11 | (equation 1)

{-11 y + 6 x = -19 | (equation 2)

Add equation 1 to equation 2:

{-(6 x) + 5 y = -11 | (equation 1)

{0 x - 6 y = -30 | (equation 2)

Divide equation 2 by -6:

{-(6 x) + 5 y = -11 | (equation 1)

{0 x + y = 5 | (equation 2)

Subtract 5 × (equation 2) from equation 1:

{-(6 x) + 0 y = -36 | (equation 1)

{0 x + y = 5 | (equation 2)

Divide equation 1 by -6:

{x + 0 y = 6 | (equation 1)

{0 x + y = 5 | (equation 2)

Collect results:

Answer: {x = 6, y = 5

The value of the probability is P(Large or Blue) = 7/10

The given parameters are represented on the table

Using the table parameters, we have

P(Large or Blue) = [(Large) + (Blue) - (Large and Blue)]/Total

This gives

P(Large or Blue) = ((17 + 8) + (17 +3) - 17)/(17 + 3 + 8 + 12)

This gives

P(Large or Blue) = 28/40

Simplify

P(Large or Blue) = 7/10

Hence, the value of the probability is P(Large or Blue) = 7/10

158.93 yd³ water it would take to completely fill the swimming pool.

Given that, a swimming pool has a volume of 32,100 gal and we have to find out that how many cubic yards of water it would take to completely fill the swimming pool.

1 cubic yard (yd³) ≈ 201.97 gallon (gal)

So, by using the conversion given above we can simply find the water in cubic yards that it would take to completely fill the swimming pool.

Volume of the swimming pool = 32,100 gal

and we know that, 1 cubic yard (yd³) ≈ 201.97 gallon (gal)

Now, we get

water needed in cubic yards to completely fill the swimming pool

= 32,100/201.97

= 158.93 yd³

Hence, 158.93 yd³ water it would take to completely fill the swimming pool.

Therefore, 158.93 yd³ is the required answer.

The length of the ladder is 58.31 inches and the angle made by the ladder with the ground is θ = 59.04°.

The distance between the ladder and the wall is 30 inches.

The height at which the ladder touches the wall is 50 inches from the ground.

Let x be the slant height when the ladder touches the wall.

Then, by using a Pythagorean theorem:

(Base)² + (Altitude)² = (Hypotenuse)²

(30)² + (50)² = x²

x² = 900 + 2500

x² = 3400 inches²

x = √[ 3400 inches²]

x = 10√34 inches

x = 58.31 inches

Then the angle made by the ladder with gound is :

tan (θ) = opposite / adjacent

tan (θ) = 50/30

tan (θ) = 5/3

θ = tan⁻¹ ( 5/3 )

θ = 59.04°

Therefore, the ladder is 58.31 inches long and the angle between the ground and the ladder is 59.04°.

Answer:

  1500z

Step-by-step explanation:

Given a bacteria population that is multiplied by z every hour, and the population after 2 hours is 1500, you want the population after 3 hours in terms of z.

The problem statement tells you the population is multiplied by z every hour. After 2 hours, the population is 800 +300 +400 = 1500. After 3 hours, that value will be multiplied by z:

  1500z . . . . . population after 3 hours

__

Additional comment

The given values of population tell us z = 1100/800 = 1.375 for the first hour, and z = 1500/1100 ≈ 1.364 for the second hour. The average value of z for the two-hour period is √(15/8) ≈ 1.369. The desired expression could be any of ...

Presumably z would have different values in each case, and we hesitate to predict what those values might be. Perhaps the population is being rounded to the nearest 10 or 100.

An exponential regression calculation models the population as ...

  p = 801.945×1.36812^t . . . . . . . z ≈ 1.36812

Using this formula, we get the given population numbers by rounding to the nearest 10.

• If b² - 4ac > 0 and a perfect square then 2 real rational roots

• If b² - 4ac = 0 then 1 real double root

• If b² - 4ac < 0 then 2 complex roots

Given

x² + 3x - 7 = 0 ← in standard form

with a = 1, b = 3, c = - 7 , then

Answer:

[tex]y = 6.495x + 6.495[/tex]

Step-by-step explanation:

Represent years with x and cost with y.

So, we have:

[tex](x_1,y_1)=(1,12.99)[/tex]

[tex](x_2,y_2)=(3,25.98)[/tex]

Required

Determine the slope intercept equation

First, we calculate the slope (m)

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{25.98 - 12.99}{3 - 1}[/tex]

[tex]m = \frac{12.99}{2}[/tex]

[tex]m = 6.495[/tex]

The equation is then calculated as:

[tex]y - y_1 = m(x - x_1)[/tex]

Where

[tex]m = 6.495[/tex]

[tex](x_1,y_1)=(1,12.99)[/tex]

[tex]y - 12.99 = 6.495(x - 1)[/tex]

[tex]y - 12.99 = 6.495x - 6.495[/tex]

Make y the subject

[tex]y = 6.495x - 6.495 + 12.99[/tex]

[tex]y = 6.495x + 6.495[/tex]
