Answer:

Burger = $15

Hot Dog = $10

Step-by-step explanation:

b=35-2h

4(b-2h)+6h=120

4(35-2h)+6h=120

140-8h+6h=120

140-2h=120

-2h=120-140

-2h=-20

h=10

b=35-2h = 35-20 = 15

Answer:

Step-by-step explanation:

The formula for the account balance from continuously compounded interest at annual rate r for t years is ...

  A = Pe^(rt) . . . . P = principal invested

  A = 8820e^(0.05·3) ≈ 10,247.38 . . . continuous compounding

__

The formula for the account balance from interest compounded semiannually at annual rate r for t years is ...

  A = P(1 +r/2)^(2t)

  A = 8820(1 +.05/2)^(2·3) ≈ 10,228.50 . . . semiannual compounding

Continuous compounding earns more.

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the first equation be = A

Now , the value of A is

x - 4y = 1   be equation (1)

Let the first equation be = B

Now , the value of B is

3x + 2y = -11   be equation (2)

Now , on simplifying both equations , we get

Multiply equation (1) by 3 , we get

3x - 12y = 3   be equation (3)

Subtracting equation (2) from equation (3) , we get

-12y - 2y = 3 - ( -11 )

-14y = 14

Divide by -14 on both sides of the equation , we get

y = -1

So , the value of y = -1

Substitute the value of y in equation (1) , we get

x - 4y = 1

x - 4 ( -1 ) = 1

x + 4 = 1

Subtracting 4 on both sides of the equation , we get

x = -3

So , the value of x = -3

Hence , the value of x is -3 and value of y is -1

Answer:

nothing times 3 is 35 so your sum cant equal 37

Step-by-step explanation:

hope this helps in some way

Answer:

Prime number: A prime number has factor of only 1 and itself.

Ex: 3: 1 and 3 are the only ways to compose 3.

A whole number that has factors other than 1 and itself is called a composite number.

Ex: 8: the factors of 8 include 1,2,4,8

Circle 5,7,2,19,3,11

Box 18,20,22,16,15,30,26,38,45,10,21,6,14

To determine the prime factorization of a number, you must break down a number into its factors. (im not sure?)

Continute until all of the factors are (im not sure)

Prime factorization is written exponential form (im not quite sure)

30= 2x3x5

30= 2^1 3^1 5^1

Answer:

"I can find the maximum or minimum by looking at the factored expression of a quadratic function by reading off its roots and taking the arithmetic average of them to obtain the [tex]x[/tex]-coordinate of the quadratic function, and then substituting that value into the function."

Step-by-step explanation:

Because of the symmetry of quadratics (which is the case here because we have two factors of degree 1, so we are dealing with a polynomial of degree 2, which is a fancy way of saying that something is a quadratic), the [tex]x[/tex]-coordinate of the extremum (a fancy way of saying maximum or minimum) is the (arithmetic) average of the two roots.

In the factored form of a quadratic function, we can immediately read the roots: 3 and 7. Another way to see that is to solve [tex](x-3)(x-7)=0[/tex], which gives [tex]x-3=0 \vee x-7=0[/tex] (the 'V' stands for 'or'). We can take the average of the two roots to get the [tex]x[/tex]-coordinate of the minimum point of the graph (which, in this case, is [tex]x=\frac{3+7}{2} = \frac{10}{2} = 5[/tex]).

Having the [tex]x[/tex]-coordinate of the extremum, we can substitute this value into the function to obtain the maximum or minimum point of the graph, because that will give the [tex]y[/tex]-coordinate of the extremum.

20/10 = 2

15/8 = 1 7/8

13/6 = 2 1/6

Hope this helped!

Answer:

6, 2, 8 7/8, 2 1/3

Step-by-step explanation:

36/6 represents a division: 36 divided by 6

answer: 6

20/10 also division: 20 divided by 10

answer: 2

15/8 also division (long division...) 15 divided by 8

you will have a remainder (that will become your numerator)

the decimal of that division is 1.875 as a fraction that is a mixed number:

8 AND 875/1000  but!! you are not done yet (that fraction has to be simplified)

If you divide the fractional portion by the greatest common factor (125) you can simplify your fraction to 8 7/8

13/6 is 13 divided by 6 = 2 with a remainder of 2 = 2 2/6 simplified = 2 1/3
