Step-by-step explanation:because it is

The tax amount for the dinner bill can be calculated with the given expression.The tax amount for the dinner bill given by Mr jaxon is $8.

Given-

Total Total amount of the bill dinner is $102.

Tips given by Mr. Jaxon [tex]t[/tex] percent is 25 percent of the dinner bill before tax.

The expression for the tip amount [tex]t[/tex] can be model as,

[tex]t=0.25(102-x)[/tex]

Here [tex]x[/tex] is the tax amount.

Put the value of  the tip in the above expression we get,

[tex]23.5=0.25(102-x)[/tex]

Divide by 0.25 both side, we get,

[tex]\dfrac{23.5}{0.25} =(102-x)[/tex]

[tex]94 =(102-x)[/tex]

Rewrite the equation for the [tex]x,[/tex]

[tex]x=102-94[/tex]

[tex]x=8[/tex]

Thus, the tax amount for the dinner bill given by Mr jaxon is $8.

Answer:

3z+2= x ; z=5

3(5)+2

15+2

17

Step-by-step explanation:

The value of the given expression at z = 5 is 45.

An algebraic expression can be obtained by doing mathematical operations on the variable and constant terms.

The variable part of an algebraic expression can never be added or subtracted from the constant part.

The given algebraic expression is 3z²− 6z.

The value of the expression at z = 5 is given as follows,

3z²− 6z

Substitute z = 5 to obtain,

3 × 5²− 6 × 5

= 75 - 30

= 45

Hence, the given expression can be simplified as 45.

Answer:

The length of the sky lift is 3.387.05 ft

Step-by-step explanation:

By an online search, i  found that the sky lift rises at an angle of 20.75 degrees.

Then we can think on a triangle rectangle, such that:

One cathetus is 1200ft, this is the opposite cathetus to the angle of 20.75°

The length of the ski lift would be the hypotenuse of this triangle rectangle.

Then we can use the relationship:

Sin(a) = opposite cathetus/hypoteuse.

such that:

a = 20.75°

opposite cathetus = 1200ft

then:

sin(20.75°) = 1200ft/hypotenuse

hypotenuse = 1200ft/sin(20.75°)  = 3.387.05 ft

The length of the sky lift is 3.387.05 ft

4. divide -16 by 8x= -2

you basically align the variables and solve down.

Answer:

C

Step-by-step explanation:

The x coordinate of the rest stop:

1/2 × (the sum of the x coordinates of the highschool and the stadium)

= 1/2 × (3+7)

= 1/2 × 10

= 5

The y coordinate of the rest stop:

- Same thing i did for the x coordinate, but use the y coordinates.

1/2 × (the sum of the y coordinates of the highschool and the stadium)

= 1/2 × (4 + 1)

= 1/2 × 5

=5/2

So the coordinate of the rest stop would be (5, 5/2).

Next for the distance, i used the pythagoras theory so it's like this:

a^2 + b^2 = c^2

Here you plot the highschool and the stadium on the coodinate plane, then connect the two dots to make a right triangle. The height of the triangle will be 3, and the base would be 4. So a=3, b=4 in the equation.

3^2 + 4^2 = c^2

9 + 16 + c^2

25 + c^2

c = 5

(Note that this isn't the real answer cuz at the end of the question it said that one UNIT equals 6.4 MILES.)

So the final answer is 5 × 6.4, which is 32. The answer is C.

Answer:

Because the total is 49.77 and the total is the bill + tip, then the tip is 49.77 - 42 or $7.77. To find the percentage, we just calculate 7.77/42 as a percentage to get 1.11/6 = (111/6)% or 37/2 percent or 18.5%

2x=−y+14

Step 2: Divide both sides by 2.

Answer:

∡BCE = 60

Step-by-step explanation:

Here, we want to find the angle marked BCE

From our diagram, the angle marked BCE is y

Looking at triangle BCE, we have the right angle, an angle measure of 30 and the angle marked y which we say is BCE

mathematically, the sum of all these will give 180 as the sum f the interior angles of a triangle is 180

Thus, we have that;

y + 30 + 90 = 180

y = 180-120

y = 60
