Answer:

x = -6

Step-by-step explanation:

Solve for x:

(4 x + 6)/2 + 3 = -6

Hint: | Put the fractions in (4 x + 6)/2 + 3 over a common denominator.

Put each term in (4 x + 6)/2 + 3 over the common denominator 2: (4 x + 6)/2 + 3 = 6/2 + (4 x + 6)/2:

6/2 + (4 x + 6)/2 = -6

Hint: | Combine 6/2 + (4 x + 6)/2 into a single fraction.

6/2 + (4 x + 6)/2 = ((4 x + 6) + 6)/2:

(4 x + 6 + 6)/2 = -6

Hint: | Add the numbers in 4 x + 6 + 6 together.

Add like terms. 6 + 6 = 12:

(4 x + 12)/2 = -6

Hint: | Multiply both sides by a constant to simplify the equation.

Multiply both sides of (4 x + 12)/2 = -6 by 2:

(2 (4 x + 12))/2 = -6×2

Hint: | Cancel common terms in the numerator and denominator of (2 (4 x + 12))/2.

(2 (4 x + 12))/2 = 2/2×(4 x + 12) = 4 x + 12:

4 x + 12 = -6×2

Hint: | Multiply 2 and -6 together.

2 (-6) = -12:

4 x + 12 = -12

Hint: | Isolate terms with x to the left hand side.

Subtract 12 from both sides:

4 x + (12 - 12) = -12 - 12

Hint: | Look for the difference of two identical terms.

12 - 12 = 0:

4 x = -12 - 12

Hint: | Evaluate -12 - 12.

-12 - 12 = -24:

4 x = -24

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of 4 x = -24 by 4:

(4 x)/4 = (-24)/4

Hint: | Any nonzero number divided by itself is one.

4/4 = 1:

x = (-24)/4

Hint: | Reduce (-24)/4 to lowest terms. Start by finding the GCD of -24 and 4.

The gcd of -24 and 4 is 4, so (-24)/4 = (4 (-6))/(4×1) = 4/4×-6 = -6:

Answer: x = -6

Answer:

61 tickets

Step-by-step explanation:

It is given that,

The total profit from the Spanish club fund-raiser varies directly with the number of dinner tickets sold.

If the sale of 22 tickets results in a profit of $253.

Profit in 1 ticket = [tex]\dfrac{253}{22}=\$11.5[/tex]

Let x tickets are sold in order to reach the fund-raising goal of $700.

[tex]x=\dfrac{22}{253}\cdot700\\\\=\$60.86[/tex]

or

= 61 tickets

Hence, 61 tickets must be sold to reach the fund-raising goal of $700.

Answer:  (a) 6760000

(b) 5760000

Step-by-step explanation:

Total letters in English alphabet = 26

Total digits = 10

Given: Each automobile license plate number consists of two letters followed by a four-digit.

(a) If there are no restrictions, then the total number of license plates formed = 26 x 26 x 10 x 10 x 10 x 10

= 6760000

(b) if the letters O and I are not used, total letters can be used ]= 26-2=24

Then the total number of license plates formed = 24 x 24 x 10 x 10 x 10 x 10

=5760000

Responder:

x = 1100

y = 2350

z = 6550

Explicación paso a paso:

Dejemos que los 3 números = x, y, z (dispuestos en orden ascendente)

Diferencia entre los dos más pequeños:

y - x = 1250

y - 1250 = x - - - (1)

Diferencia entre los dos más grandes:

z - y = 4200

z = 4200 + y - - - (2)

x + y + z = 10000 - - - (3)

Sustituya (1) y (2) en (3)

y - 1250 + y + 4200 + y = 10000

3 años + 2950 = 10000

3 años = 7050

y = 2350

x = 2350-1250

x = 1100

z = 4200 + 2350

z = 6550

Answer:

Y= 3

Step-by-step explanation:

To do this u can subtract -4 on each side. Whatever u do to one side of the equal sign u have to do to the other.

+4 and -4 cancel each other out

-11 + -4 = -15

The next step is to divide -5y on each side.

-5y divide by negative -5y cancel each other out leaving the y isolated.

-15 divided by -5 gives u positive 3.

So the answer is y=3

Answer:

10m

Step-by-step explanation:

formula to find volume of a cube is v=a ³

if the volume of the cube is 1000, then 1000=a³ (a being the length of an edge of the cube)(the edges of a cube are all the same length)

cube root of 1000 is 10

The required height of the cubed aquarium tank is 10 meters.

As given that, A cubed aquarium tank holds 1,000 m³ of water, the height of the aquarium is to be determined.

Volume is defined as the ratio of the mass of an object to its density.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
A cubed aquarium tank holds 1,000 m³ of water,
The volume of the cube = 1000
side ³ = 1000
side = ∛1000
side = 10

Thus, The required height of the cubed aquarium tank is 10 meters.

Answer:

three small smoothies require one and one-third bananas.

Step-by-step explanation:

Assuming that the three small smoothies are equal, and their sum equals the one large smoothie;

Number of bananas required for one large smoothie = three and three-third

three-thirds mean that out of three parts, three parts were selected. Therefore, three-thirds is the same thing as a whole or 1

∴ three and three-third  [tex]= 3 + \frac{3}{3} = 3 + 1 = 4[/tex]

Therefore, the one large smoothie required 4 bananas.

Large smoothie = 4 bananas

three small smoothies [tex]= \frac{4}{3} = 1 \frac{1}{3}[/tex]

Hence, three small smoothies require one and one-third bananas.

Answer:

55.648

Step-by-step explanation:

The easiest way is turning both of these numbers into whole numbers by moving the decimal point to the right twice for both numbers. Now our equation will be....

376*1480

Now, we can solve this.

the answer to that equation is 556480.

Since we moved the decimal point to the right before, we have to move it to the left the same amount. Since we moved both of the numbers decimal point to the right twice, we add 2+2 to get 4 which means we have to move the decimal point to the left 4 times.

Our final answer : 55.648

Step-by-step explanation:

We have been given that Judi is making a rope ladder. She uses 1/2 yard of rope for each step.

Since Judi makes each step of ladder with 1/2 yard of rope, so one yard of rope will make two steps.

Therefore, Judi can make 12 steps of ladder from 6 yards of rope.

Answer:

1) Domain: -∞ < x < +∞

2) Range: y > 0

3) y intercept: (0, 200)

4) Asymptote: y = 0

5) The growth rate; r = 0.08

6) The growth factor = 1.08

7) End Behavior: As x → -∞, f(x) → 0

8) End Behavior: As x → +∞, f(x) → +∞

Step-by-step explanation:

1) The domain of the function is given as the x values for which the function is valid which includes from -∞ < x  to +∞

2) The range of the function, are the range of the output values of the function for the given range of the input values

For the function, f(x) = 200·(1.08)ˣ, we have, f(x) = y > 0, for all values of x

3) The y-intercept is the value of y, when x = 0, given as follows;

y intercept = f(0) = 200·(1.08)⁰ = 200 × 1 = 200

4) The asymptote is the line that the function approaches but never reaches

In the question, as x tends to -∞, the function f(x) approaches 0. Therefore, f(x) = y = 0 is the asymptote of the function

5) The growth rate of an exponential function, y = a(1 + r)ˣ is r

Therefore, for the function, 200·(1.08)ˣ, which is equivalent to 200·(1 + 0.08) ˣ, the growth rate = 0.08

6) The growth factor of an exponential function, y = a(1 + r)ˣ is (1 + r)

Therefore, for the function, 200·(1.08)ˣ, which is equivalent to 200·(1 + 0.08) ˣ, the growth factor = (1 + 0.08) = 1.08

7) The end behavior as x tends to -∞, [tex]f(x) = y= 200 \cdot (1.08) ^{-\infty} \rightarrow 0[/tex]

8) The end behavior as x tends to +∞, [tex]f(x) = y= 200 \cdot (1.08) ^{-#+\infty} \rightarrow + \infty[/tex]

The texts that complete the blanks are:

The domain

The domain of an exponential function is all set of real numbers.

So, the domain is: -∞ < x < +∞

The range

The range of an exponential function is always greater than 0.

So, the range is y > 0

The y-intercept

This is when x = 0.

So, we have:

[tex]f(x) = 200(1.08)^x[/tex]

This gives

[tex]f(0) = 200(1.08)^0[/tex]

[tex]f(0) = 200[/tex]

So, the y-intercept is (0,200)

The asymptote

This is the line that is close to the function but is not on the function.

The range is:

y > 0.

So, the asymptote is y = 0

The growth rate and the growth factor

The function is given as:

[tex]f(x) = 200(1.08)^x[/tex]

The growth factor is 1.08, while the growth rate (r) is calculated as:

[tex]r = 1.08 - 1[/tex]

[tex]r = 0.08[/tex]

Hence, the growth rate is 0.08, and the growth factor is 1.08

The end behavior

The end behavior of an exponential growth function is:

a x → -∞, f(x) → 0 and as x → +∞, f(x) → +∞
