Answer:

x=5

Step-by-step explanation:

Answer:

m = 8

k = 7

Step-by-step explanation:

Diagonals of a parallelogram bisect each other. This implies that:

m = 8, also,

k + 4 = 11

k = 11 - 4 (subtraction property of equality)

k = 7

Step-by-step explanation:

Answer:

9 bookcases

Step-by-step explanation:

(6 1/4) divide by 2/3 convert the first one to a mixed fraction, 6*4 =24 +1 = 25/4

and then common denominator 2/3 = 8/12 and 25/4 = 75/12 and then 75 / 8 = 9.----- but you can only paint 9.

Answer: $1.60

Step-by-step explanation:

Bag of soil normally sells for $15.99.

If it is discounted by 10%, a person can save:

= 15.99 * 10%

= 1.599

= $1.60

Answer:

m=1/2, b=1

Step-by-step explanation:

y=1/2x+1

y=mx+b

y is the y coordinate

m is the slope

x is the x coordinate

b is the y-intercept

You would identify that 1/2 is substituted into the equation as m aka the slope and 1 substituted for the b value aka y-intercept

Answer:

(a+2) (a-18)

Step-by-step explanation:

Factoring a2-16a-36

The first term is, a2 its coefficient is 1 .

The middle term is, -16a its coefficient is -16 .

The last term, "the constant", is -36

Step-1 : Multiply the coefficient of the first term by the constant 1 • -36 = -36

Step-2 : Find two factors of -36 whose sum equals the coefficient of the middle term, which is -16 .

-36 + 1 = -35

-18 + 2 = -16 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -18 and 2

a2 - 18a + 2a - 36

Step-4 : Add up the first 2 terms, pulling out like factors :

a • (a-18)

Add up the last 2 terms, pulling out common factors :

2 • (a-18)

Step-5 : Add up the four terms of step 4 :

(a+2) • (a-18)

Which is the desired factorization

Answer: w= -10

Step-by-step explanation: move all terms not containing w to the right side of the equation

Answer:

You multiply 5 by 1/5 to get 1. So with 2x, you multiply by 1/(2x) to get 1. That's about all you know, since we only know that x is positive.

Answer:

[tex]\frac{25}{10x-1}[/tex]

Step-by-step explanation:

The multiplicative inverse of "a" is " [tex]\frac{1}{a}[/tex] "

a × [tex]\frac{1}{a}[/tex] = 1

~~~~~~~~~~~

[tex]\frac{1}{5}[/tex] ( 2x - [tex]\frac{1}{5}[/tex] ) = [tex]\frac{2}{5}[/tex] x - [tex]\frac{1}{25}[/tex]

1 ÷ ( [tex]\frac{2}{5}[/tex] x - [tex]\frac{1}{25}[/tex] ) = 1 ÷ ( [tex]\frac{10x}{25}[/tex] - [tex]\frac{1}{25}[/tex] ) = 1 ÷ ( [tex]\frac{10x - 1}{25}[/tex] ) = [tex]\frac{25}{10x-1}[/tex]

The multiplicative inverse of the product is  [tex]\frac{25}{10x-1}[/tex]

Answer:

12a^3b^4

Step-by-step explanation:

area of triangle = bh/2

area = 3ab^3 * 8a^2b / 2

area = 24a^3b^4/2

area = 12a^3b^4

Answer:

0.8

Step-by-step explanation:

5 is divided by 5 to get to 1. Divide 4 by 5 to get 0.8.

In a ratio, whatever you do to one side you have to do to the others.

Answer:

it will be

4/5 : 1 or 0.8 : 1

in n : 1 form

Answer:

the dimensions are 3 and 6 feet

Step-by-step explanation:

xy=18

x+y=9

x=9-y

y(9-y)=18

-y^2+9y -18=0

y^2-9y+18=0

(y-6)(y-3)=0

if y=6, x=3

if y=3, x=6

Answer:

38

Step-by-step explanation:

Answer: Elena's running speed = 5 miles per hour.

Step-by-step explanation:

Length of track = [tex]\dfrac14 \text{ mile}[/tex]

Time taken to complete one lap = [tex]\dfrac{1}{20}[/tex] of an hour.

Elena's running speed = [tex]\dfrac{Distance}{Time}[/tex]

[tex]=\dfrac{\dfrac14}{\dfrac1{20}}\text{ miles per hour}\\\\=\dfrac{20}{4}\text{ miles per hour}\\\\=5\text{ miles per hour}[/tex]

Hence, Elena's running speed = 5 miles per hour.

The answer is A. One / 1

Answer:

The answer is C. -1

<NPQ = <NMQ i believe, making it so that <NPQ is 62 degrease

Answer:

118 degrees

Step-by-step explanation:

quadrilaterals add up to 360

NMQ is 62 degrees so MPQ must be too

62 x 2=124   360-124=236

236/2=118

Answer:

The correct answer is Option B: $39000

Step-by-step explanation:

Given that

Price of House = P = $650000

Rate of commission = r= 6%

In order to calculate the commission amount of Kathy, we only have to calculate 6% of $650000 or by simply multiplying the price by 0.06

So,

[tex]Commission = 6\%\ of\ 650000\\=0.06*650000\\=39000[/tex]

The commission is: $39000

Hence,

The correct answer is Option B: $39000

Answer:

c =2

Step-by-step explanation:

2(6c+2)+3c=2 (19 -c)

1. Distribute

2(6c +2 ) + 3c = 2 ( 19 - C )

12c + 4 +3c = 2 (19 - C )

2. Combine like terms

12c + 4 + 3c = 2 ( 19 - c )

15c + 4 = 2 (19 - c )

3. Rearrange terms

15c + 4 = 2( 19 - C )

15c + 4 = 2 ( -c + 19 )

4. Distribute

15c + 4 = 2 ( -c + 19 )

15c + 4 = -2c + 38

5. Subtract 4 from both sides of the equation

15c + 4 = -2c + 38

15c + 4 -4 = -2c + 38 -4

6. Simplify

Subtract the numbers

Subtract the numbers

15c = -2c +34

7. Add 2c to both sides of the equation

15c = -2 +32

15c +2c = -2c + 34 + 2c

8. Simplify

Combine like terms

Combine like terms

17c = 34

9.Divide both sides of the equation by the same term

17c = 34

17c/17 = 34/17

10. Simplify

Cancel terms that are in both the numerator and denominator

Divide the numbers

c = 2
