Answer:

x + y + z = 49

2.50x + 7y + 1.50z = 147

y + 7 = z

Step-by-step explanation:

Before you even start setting up the equations, create variables for information needed, but not given in the problem:

Variable x = number of tacos

Variable y = number of burritos

Variable z = number of sodas

The first piece of information we are given is the number of items so make this into an equation:

x + y + z = 49

Next we are told how much everything cost in total so make this into an equation:

2.50x + 7y + 1.50z = 147

Lastly, we are informed Rosa bought 7 more sodas than burritos so form an equation using this information:

y + 7 = z

Answer:

Step-by-step explanation:

g(f(x)) = g(x²) = x²- 3

f(g(x)) = f(x-3) = (x-3)² = x²+ 6x + 9

The composition of two functions will be ; f(g(x)) = x²+ 6x + 9 and g(f(x)) = x² - 3.

Two functions f(x) and g(x) are given in the question.

We have to find the composition of the two functions.

What is a function ?

The function is the description of how the inputs relate to the output. Each input has only one output.

As per the question ,

f(x) = x²

g(x) = x - 3

The composition of these two functions can be defined as ;

   g(f(x)) = g ( x² )  

⇒ g(f(x)) = x²- 3

and

   f(g(x)) = f(x-3)

   f(g(x)) = (x-3)²

⇒ f(g(x)) = x²+ 6x + 9

Thus , the composition of two functions will be ; f(g(x)) = x²+ 6x + 9 and g(f(x)) = x² - 3.

Answer:

Step-by-step explanation:

Given,

Length of the rectangle = 12 meters = 1200 cm

Width of the rectangle = 400 cm

Therefore,

Perimeter of the rectangle = 2(l+w)

= 2(1200+400) cm

= 2 × 1600 cm

= 3200 cm (Ans)

Answer:

3200 cm

Step-by-step explanation:

12m = 12,000 cm so therefore the answer is 3200cm

Answer:

-19

Step-by-step explanation:

-13-25-24-14

= -76/4

= -19

Answer:

Let x=Width

Length = 7x-22 (22m less the 7 times width)

A=L*w

A=(7x_22)x

7805=7x^2-22x

7x^2-22x-7805=0

(7x-223) (7x+223)=0

7x-223=0

7x=223

x=223%7

x=35

Now,

Length =7x-22

=7(35)-22

=223

therefore,length =223

If the area of the rectangle is 7805 square meters, The length of the rectangle will be 223 units

It is defined as two-dimensional geometry in which the angle between the adjacent sides is 90 degrees. It is a type of quadrilateral. The area occupied by the rectangle in two-dimensional planner geometry.

The area of a rectangle can be calculated using the following formula:

Rectangle area = length x width

It is given that, A rectangle has a length of 22 meters less than 7 times its width. If the area of the rectangle is 7805 square meters,

Suppose the width of the rectangle is x.

Length = 7x-22 (22m less the 7 times width)

A=L*w

A=(7x_22)x

7805=7x²-22x

7x²-22x-7805=0

(7x-223) (7x+223)=0

7x-223=0

7x=223

x=223/7

x=35

As a result

Length =7x-22

=7(35)-22

=223 units.

Thus, if the area of the rectangle is 7805 square meters, The length of the rectangle will be 223 units

Answer:

∠DAC is 35°

Step-by-step explanation:

Given:

Measure of ∠DAB = 64°

Measure of ∠CAB = 29°

Solution:

∠DAB shows the value of the overall angle.

∠CAB shows the value for almost half of the angle.

∠DAB - ∠CAB = ∠DAC

64° - 29° = ?

∴ 64° - 29° = 35°

Here we want to make a system of equations and solve it for the smallest angle of a triangle.

We will find that the smallest angle is 5.625°

First, let's define the variables:

a₁ = smallest angle

a₂ = middle angle

a₃ = largest angle.

We know that the sum of all interior angles of a triangle is equal to 180°, then we can write:

a₁ + a₂ + a₃ = 180°

We also know that:

"the largest angle of a triangle is the sum of the other two angles"

This can be written as:

a₃ = a₁ + a₂

And we know that:

"The smallest angle is one 16th of the largest angle"

Then:

[tex]a_1 = \frac{a_3}{16}[/tex]

Writing together these 3 equations we get our system:

a₁ + a₂ + a₃ = 180°

a₃ = a₁ + a₂

[tex]a_1 = \frac{a_3}{16}[/tex]

Now we want to solve this for a₁

To do it we need to replace equations into other equations.

How do we do this?

Notice that in the third equation we have:

a₃ = a₁ + a₂

Then we can replace it in the first equation:

a₁ + a₂ + a₃ = 180°

(a₁ + a₂) + a₃ = 180°

a₃ + a₃ = 180°

2a₃ =  180°

a₃ =  180°/2 = 90°

a₃ = 90°

Now we can use the last equation:

[tex]a_1 = \frac{a_3}{16}[/tex]

To get the value of the smallest angle:

[tex]a_1 = \frac{90 \°}{16} = 5.625 \°[/tex]

Step-by-step explanation:

Recall that [tex]7^a\cdot 7^b = 7^{a+b}[/tex]

So now

[tex]7^{2/3} \cdot 7^{1/3}\\= 7^{\frac{2}{3}+\frac{1}{4}}\\=7^{\frac{8}{12}+\frac{3}{12}}\\=7^{11/12}[/tex]

The equivalent value of the expression is A = 7^ ( 11/12 )

When you raise a quotient to a power you raise both the numerator and the denominator to the power. When you raise a number to a zero power you'll always get 1. Negative exponents are the reciprocals of the positive exponents.

The different Laws of exponents are:

mᵃ×mᵇ = mᵃ⁺ᵇ

mᵃ / mᵇ = mᵃ⁻ᵇ

( mᵃ )ᵇ = mᵃᵇ

mᵃ / nᵃ = ( m / n )ᵃ

m⁰ = 1

m⁻ᵃ = ( 1 / mᵃ )

Given data ,

Let the exponential equation be represented as A

Now , the value of A is

Let the first number be p = 7 ^ ( 2/3 )

Let the second number be q = 7 ^ ( 1/4 )

And , A = pq

On simplifying , we get

A = 7 ^ ( 2/3 ) . 7 ^ ( 1/4 )

From the laws of exponents , we get

mᵃ×mᵇ = mᵃ⁺ᵇ

So , A = 7 ^ ( 2/3 + 1/4 )

A = 7 ^ ( 11/12 )

Hence , the equation is 7^ ( 11/12 )

Hence,

Total ride cost = $8 + (fee per minute × number of Minutes)

If total Cost of ride = $12.14

Let number of minutes = m

Hence, we have :

12.14 = 8 + 0.06m

12.14 - 8 = 0.06m
