Answer:

$18

Step-by-step explanation:

378 ÷ 27 = 14

14 + 4 = 18

The normal cost per person = $18

The normal cost per person is $18.

Given,

Brad's science class is heading to Skylight Observatory on a field trip.

The observatory offers a group rate for students that is $4 less per person than the normal cost.

There are 27 students in Brad's science class.

The total cost for the class is $378.

We need to find the normal cost per person.

We divide the total cost by the number of items.

Example:

7 bags cost $49

1 bag cost = $49 / 7 = $7

We have,

The number of students = 27

The total cost of the class trip with the offer =  $378

Offer = $4 less than the normal cost per student

Now,

The offer cost for each person:

= $378 / 27

= $14

The normal cost for each person:

= $14 + $4

= $18

Thus the normal cost per person is $18.

Answer:

y = 140

Step-by-step explanation:

you'd do:

y=25(7)-35

y=175-35

y=140

to double-check your math:

140 = 25(7)-35

both sides will equal 140 (or the same value) if done properly

Step-by-step explanation:

→ 70 = 19 - 3x

→ - 19 + 70 = -3x

→ 51 = -3x

→ -3x = -51

→ x = -51/3 = -17

→ x = -17

therefore, value of x is -17.

hope this answer helps you dear!

Answer:

Answer: I believe it is a. Sorry if I am incorrect

Step-by-step explanation:

Functions assign outputs to inputs. The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0.

Answer:

I believe, that they are parallel because they both have 90° angles meaning that the other angle has to be 90° as well. I dont really know how to explain it but they are both in the same position and have 90° angles im not the best with these. •So im not exactly sure if this is correct though.

-They also have corresponding and congruent angles that do match up, so yes they are parallel to eachother

Step-by-step explanation:

length of a rectangle = 2b - 8c

breadth of a rectangle = 10b + 6c

now , formula to calculate the perimeter of rectangle is

p = 2 (l + w)

no substitute the value of l(length) and w(width)

p = 2{(2b - 8c) + (10b + 6c)}

p = 2(2b - 8c + 10b + 6c)

p = 2(12b - 2c)

p = 24b - 4c

Answer:

[tex] \frac{ {x}^{2} + - 4x - 2 }{ {x}^{2} - 4 } + \frac{8x + 6}{{x}^{2} - 4} \\ = \frac{ {x}^{2} + - 4x + 8x - 2 + 6 }{ {x}^{2} - 4 } \\ = \frac{ {x}^{2} + 4x + 4 }{ {x}^{2} - 4 } \\ = \frac{ {(x + 2)}^{2} }{(x - 2)(x + 2)} \\ = \frac{x + 2}{x - 2} [/tex]

Answer:

[tex]\sf f^{-1}(x) = \dfrac{x}{2}+4[/tex]

Step-by-step explanation:

A function is given to us and we need to find the inverse of the function in slope intercept form . The given function is ,

[tex]\sf\implies f(x) = 2x - 8 [/tex]

Let us assume that y = f(x) , so that ,

[tex]\sf\implies y = 2x - 8 [/tex]

Now interchange the positions of x and y , we have ,

[tex]\sf \implies x = 2y - 8[/tex]

Solve for y in terms of x ,

[tex]\sf \implies 2y = x + 8 \\\\\sf\implies y =\dfrac{x}{2}+4 [/tex]

This is the inverse of the function in slope intercept form. Now we can replace this y with f-¹(x) , as ,

[tex]\sf \implies \boxed{\pink{\frak{f^{-1}(x) = \dfrac{x}{2}+4}}}[/tex]

Answer:

x = 4

y = 2

Step-by-step explanation:

the third angle of the triangle

180 - (148 + 18) = 14º

Therefor

3x + y = 14

5x - y = 18

Add the equations

8x = 32

Divide both sides by 8

x = 4

Plug in x = 4

3(4) + y = 14

12 + y = 14

y = 2

9514 1404 393

Answer:

  (x, y) = (4, 2)

Step-by-step explanation:

The triangles are similar by AA similarity, so the corresponding angles are congruent.

  5x -y = 18 . . . . . . unmarked angles are congruent

  18 +(3x+y) +148 = 180 . . . . . sum of angles in a triangle is 180°

__

After subtracting 166 from both sides, the second equation simplifies to ...

  3x +y = 14

Adding this to the first equation gives ...

  8x = 32

  x = 4 . . . . . . divide by 8

Then substituting for x in the first equation gives ...

  5(4) -y = 18

  20 -18 = y = 2

The values of the variables are x = 4, y = 2.

The angle marked with a double mark is 14°, given by the simplified second equation.
