Anyone help me with this please:)

Answer:

=−3

Step-by-step explanation:

Answer:

B) x = -3

Step-by-step explanation:

3x - 4 = 7x + 8.

Subtract 7 from 3

3 - 7 = -4

-4x - 4 = 8

use additive inverses.

-4x - 4 + 4 = 8 + 4

8 + 4 = 12.

-4x ÷ -4 = 12 ÷ -4

x = -3.

Hope this helped.

Answer:

[tex]-x-3[/tex]

Step-by-step explanation:

They want you to simplify the expression.

Step 1: Apply the distributive property.

[tex]\frac{1}{5} (5x)+\frac{1}{5} (-15-2x)[/tex]

Step 2: Cancel the common factor of 5.

[tex]x+\frac{1}{5} (-15-2x)[/tex]

Step 3: Cancel the common factor of 5.

[tex]x-3-2x[/tex]

Step 4: Subtract 2x from x.

[tex]-x-3[/tex]

59 cents

Step-by-step explanation:

When finding the unit rate, you need to end up finding what is the price for one product (basically a fraction with one on the bottom) to find this I just did 3.55 / 6 which gave me 59 cents, the price of one coca cola bottle.

Answer:

A proportional relationship is any relationship that stays constant. since both sides of the equation do not change, this is a proportional relationship

Answer:

 The probability is  [tex]P( | \^ p - p| > 0.03) =0.9945[/tex]

Step-by-step explanation:

From the question we are told that

   The population proportion is  [tex]p = 0.05[/tex]

    The sample size is  n =  408

Generally the standard deviation of the sampling distribution is mathematically represented as

       [tex]\sigma = \sqrt{\frac{p (1- p)}{n} }[/tex]

=>    [tex]\sigma = \sqrt{\frac{ 0.05 (1- 0.05)}{408} }[/tex]

=>    [tex]\sigma = 0.0108[/tex]

Generally the probability that the sample proportion will differ from the population proportion by greater than 0.03 is mathematically represented as

        [tex]P( | \^ p - p| > 0.03) = P( \frac{|\^ p - p | }{\sigma } > \frac{0.03}{0.0108} )[/tex]

[tex]\frac{|\^ p -p |}{\sigma }  =  |Z| (The  \ standardized \  value\  of  \ |\^ p -p | )[/tex]

So    

       [tex]P( | \^ p - p| > 0.03) = P( |Z|> 2.778 )[/tex]

=>   [tex]P( | \^ p - p| > 0.03) = P( Z < 2.778) - P(Z < -2.777)[/tex]

From the z table  the area under the normal curve to the left corresponding to  2.778  and  -2.778  is

     [tex]P( Z < 2.778) = 0.99727[/tex]

and

     [tex]P( Z < -2.778) = 0.0027347[/tex]

So

     [tex]P( | \^ p - p| > 0.03) = 0.99727 - 0.0027347[/tex]

=>  [tex]P( | \^ p - p| > 0.03) =0.9945[/tex]

Answer:

Although the main objective of the Medieval fairs were trade and commerce, every fair contained some element of merry-making. Possibly starting from merchants trying to sell their goods, people were determined to attract the most customers to their stalls. ... Medieval tournaments sometimes coincided with Medieval fairs.

Step-by-step explanation:

Answer: 10,11,12

Step-by-step explanation:

1st integer= x-1

2nd integer= x

3rd integer= x+1

(x-1)(x) = 11(x+1)-22

x^2-x = 11x+11-22

simplify to: x^2-12x+11=0

factor to: (x-11)(x-1)

x=11, 1

1 doesn’t work because that would make the 1st integer equal to 0, and 0 isn’t a positive integer. So the three integers are 10, 11, and 12.

Answer:

A. 10.00, so total price is currently 40.00

B. 42.8

C. Total amount is 51.36

Step-by-step explanation:

20% of 50 is 10. Taking off 10% (your discount) would make it 40.

7% of 40 is 2.8. The total amount is now 42.8

20% (your tip) of 42.8 = 8.56.

42.8 + 8.56 = 51.36.

51.36 is your final cost.

Step-by-step explanation:

Answer:

Width = 4 in

Length = 8 in

Step-by-step explanation:

Given:

Area of a rectangle = 32 in²

Find:

Length and width

Computation:

Assume;

Width = x

Length = x + 4

Area of a rectangle = lb

32 = (x+4)(x)

x² + 4x = 32

x² + 4x - 32 = 0

x² + 8x - 4x - 32 = 0

x(x+8) - 4(x+8) = 0

(x-4)(x+8)

x = 4 , x = -8

So,

Width = x = 4 in

Length = x + 4 = 4 + 4 = 8 in

Answer:

5/4 kg is Parcel A

im guessing what you meant was that parcel B is 3 times as heavy as A.

Step-by-step explanation:

Lets say parcel A is x

3x would be parcel b

x + 3x = 5 kg

4x = 5 kg

x = 5/4 kg

Answer:

≈3.11

Step-by-step explanation:

The value of the quantity after 21 days, to the nearest hundredth, given the expoenential decay is 3.11.

When a quantity decays , it means that the value of the quantity declines with the passage of time.

The formula that can be used to determine the value of the quantity after a number of weeks is :

FV = P (1 - r)^n

Where:

920 x (1 - 0.85)^3

920 x 0.15^3 = 3.11

Step-by-step explanation:

Answer:

=  -5√7 -(√2)

Step-by-step explanation:

3√7- √7 -2√7+√8 -5√7-3√2

=3√7- √7 -2√7 -5√7+√8 -3√2   (first we place similar radicands together)

=-5√7+√8 -3√2                     ( solve the similar radicands)

=-5√7+√2³ -3 (2^1/2)          ( break 8 into powers of 2)

=-5√7+ (2)^3/2  -3 (2^1/2)        (solve 2 power with the radical sign)

=  -5√7+(2^1/2){ 2-3}             ( taking2^1/2 as common)

=  -5√7+(2^1/2){ -1}                  ( solving the co - efficients of 2^1/2)

=  -5√7 -1 (2^1/2)  

=  -5√7 -(√2)          {answer}
