HELP!!!!

The total cost of Anja’s trip to the dentist was $628.35. She paid a flat fee of $89.95 which included the checkup and cleaning and then had 4 cavities filled, each of which cost the same amount. Which shows the correct equation and value of x, the cost of each cavity filling?

A. 4 x + 89.95 = 628.35; x = 134 dollars and 60 cents

B. 4 (89.95) + x = 628.35; x = 268 dollars and 55 cents

C. 4 x + 89.95 = 628.35; x = 179 dollars and 58 cents

D. 4 (89.95) + x = 628.35; x = 538 dollars and 40 cents

Answer:

Therefore, the birds visited the feeder = 96

Step-by-step explanation:

Five out of eight birds that visited the feeder ate the birdseed.

i.e. the ration is: 5/8

Given that 60 birds ate the birdseed today.

Note that if we multiply '5' by '12', we get the number 60.

Now, all we need to is to also multiply '8' by '12' to maintain the initial ratio which is 5/8.

i.e. (5×12) / (8×12) = 60/96

Therefore, the birds visited the feeder = 96

Answer:

28 shirts

Step-by-step explanation:

Let's see what we are given.

there are x amount of shirts ($616 total)

there are 12 in a dozen

the regular shirts are $16

the last 12 shirts are $14

Lets make an equation.

616= 14(12) + 16x

616=168+16x

448=16x

x=28

(Sorry if this explanation is bad)

Answer:

x>-33/2

Step-by-step explanation:

this is because you must solve the equation. when you divide by a negative number in order to get the x alone the sign of the inequality flips.

Answer:

[tex]x > \frac{ - 11 - 22}{2} [/tex]

Step-by-step explanation:

Step 1: Subtract 7x7x from both sides.

−11<9x+22.−7x

Step 2:Simplify 9x+22.-7x9x+22.−7x to 2x+22.2x+22.

−11<2x+22.

Step 3:Subtract 22.22. from both sides.

−11−22.<2x

Step 4:Divide both sides by 22.

[tex] \frac{ - 11 - 22}{2} < x[/tex]

Step 5, Switch sides.

[tex] x > \frac{ - 11 - 22}{2} [/tex]

I hope it helps you.

Answer:

Step-by-step explanation:

triangles have always total degrees as  180 degrees

let the 3 rd angle be x

so , 70 + 62 + x = 180

70 + 62 = 132

132 + x = 180

x = 180 - 132

x = 52 degrees

Answer:

Simplifying

y = 12x + 25

Reorder the terms:

y = 25 + 12x

Solving

y = 25 + 12x

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Simplifying

y = 25 + 12x

Step-by-step explanation:

To evaluate g(1) , substitute x = 1 into g(x), that is

g(1) = 4 - 2(3 - 1)

      = 4 - 2(2)

      = 4 - 4

      = 0

Answer: 91

Step-by-step explanation:

Angle between the two vectors u and v is option (a) 0 degree

Vector, in mathematics, a quantity that has both magnitude and direction

Given,

u=(-2,3)

v=(-6,9)

Angle between the two vectors θ =[tex]cos^{-1} \frac{u.v}{|u| |v|}[/tex]

[tex]u.v=(-2)(-6)+(3)(9)\\u.v=12+27\\u.v=39[/tex]

[tex]|u|=\sqrt{-2^{2}+3^{2} } \\|u|=\sqrt{13}[/tex]

[tex]|v|=\sqrt{-6^{2}+9^{2} } \\|v|=\sqrt{117}[/tex]

Angle between two vectors θ =[tex]cos^{-1} \frac{u.v}{|u| |v|}[/tex]

θ=[tex]cos^{-1} \frac{39}{\sqrt{13}.\sqrt{117} } \\cos^{-1}\frac{39}{39}\\ cos^{-1}1=0[/tex]

Hence, the angle between the vectors u and v is 0 degree
