Step-by-step explanation:

[tex]-\dfrac23y-\dfrac35x+\dfrac29-\dfrac45x+\dfrac13y[/tex]

Collect like terms:

[tex]\implies -\dfrac23y+\dfrac13y-\dfrac35x-\dfrac45x+\dfrac29[/tex]

Combine like terms:

[tex]\implies -\dfrac13y-\dfrac75x+\dfrac29[/tex]

[tex]\dfrac13y-\dfrac75x+\dfrac23-\dfrac23y-\dfrac49[/tex]

Collect like terms:

[tex]\implies \dfrac13y-\dfrac23y-\dfrac75x+\dfrac23-\dfrac49[/tex]

Combine like terms:

Thomas uses 4 1/2 cups of flour to make 3 loaves of banana bread. Write and solve an equation to find how many cups of flour are needed to make one loaf of banana bread.

Answers

The equation that best represents the relationship between the number of loaves of bread which is denoted by b and the number of cups of bananas which is denoted by c is c = 2 1/4b.

We know that we need 11 ¼ cups of bananas are needed to make 5 loaves of bread.

We need to divide 11 ¼ to 5 which the answer is 2 ¼. The 2 ¼ represents how many cups are needed to make 1 loaf of bread.

Answers

State B with the second-lowest population has the lowest population density. Then the correct option is B.

What is decision-making?

The process of making choice is by identifying the correct decision, gathering information, and assessing alternative solutions.

The second-lowest density for the states will be given as

[tex]\rm D_A = \dfrac{1055173}{2677} = 394.16[/tex]

[tex]\rm D_B = \dfrac{1333089}{36418} = 36.61[/tex]

[tex]\rm D_C = \dfrac{3596677}{5543} = 648.87[/tex]

[tex]\rm D_D = \dfrac{6745408}{10555} = 639.07[/tex]

Thus, state B with the second-lowest population has the lowest population density. Then the correct option is B.

105° = 57° + ∠BCA

Subtracting 57 to both sides

∠BCA = 105°-57°

PLEASE HELP!! What is the equation of the following graph in vertex form?

Answers

Answer:

             y = (x - 4)² - 4

Step-by-step explanation:

The vertex form of an equation of the parabola:  

                                                      f(x) = a(x - h)² + k

the vertex is (4, -4)  ⇒   h = 4,  k = -4

so:

  f(x) = a(x - 4)² + (-4)

    f(x) = a(x - 4)² - 4

So the right answer is the first one.

Please explain

Answers

Answer:

X = 10

Step-by-step explanation:

Multiply both sides of the equation by 5

x + 2x - 60 = -30

Collect like terms

3x - 60 = -30

Move constant to the right-hand side and change its sign

3x = -30 + 60

Calculate the sum

3x = 30

Divide both sides of the equation by 3

x = 10

Solution

x = 10

Answer: x = 10

Step-by-step explanation:

1/5x + 2/5x - 12 = -6    Add 12 to both sides

                   +12    +12

1/5x + 2/5x = 6     Combine like terms on the left side

3/5x = 6         Divide both sides by 3/5

x =  10

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is,

⇒ ([x/(y - 1)](-4) - [xy + (-3)]/ (-1)

Now, We can put x and y in above expression as;

⇒ ([x/(y - 1)](-4) - [xy + (-3)]/ (-1)

⇒ [- 5 / (- 2 - 1) ] (- 4) - [- 5×- 2 + (- 3)] / (- 1)

⇒ [ - 5/- 3 ] (- 4) - [10 - 3] / (- 1)

⇒ - 20/3 + 7

Answers

Answer:

mode is 16

Step-by-step explanation:

because there are 3 16s which is the most common number in this data set

Answer:

16

Step-by-step explanation:

Your mode would be 16

Your mode is 16 because the mode is the number that appears most in the data set and 16 appears 3 times in the data set.

Here is some extra answers just incase.


median=14.5

Because median is the middle number and because 13,16 are the middle numbers then you split that in middle and plus you also have to sort it least to gretest.

Mean=14.5 also because mean is the average of all the numbers in the data set.

range is 8

Range is the highest number subtracting lowest number so 19-11=8

Minimum is 11

The minimum is the lowest number and the data set so 11

maximum is 19

Maximum is the highest number in the data set.

47 = 2(x + 3) + 3(x - 3)
what's the answer to this ?

Answers

the answer should be x=10

[tex]47 = 2(x + 3) + 3(x - 3)[/tex]

[tex]47 = 2x + 6 + 3x + - 9[/tex]

[tex]47 =(2 x + 3x) + (6 + - 9)[/tex]

[tex]47 = 5x + - 3[/tex]

[tex]47 = 5x - 3[/tex]

[tex]5x - 3 = 47[/tex]

[tex]5x = 47 + 3[/tex]

[tex]5x = 50[/tex]

[tex]x = \frac{50}{10} [/tex]

[tex]x = 10[/tex]

Let us check whether or not we have found out the correct value of x by placing 10 in the place of x .

So :-

[tex]47 = 2(10 + 3) + 3(10 - 3)[/tex]

[tex]47 = (20 + 6) + (30 - 9)[/tex]

[tex]47 = 26 + 21[/tex]

[tex]47 = 47[/tex]

LHS = RHS

As the left hand side of the equation is equal to the right hand side of the equation , we have found out the correct value of x .

Therefore , 47 = 2 ( 10 + 3 ) + 3 ( 10 - 3 ) and x = 10 .
