bazaltina [42]3 years ago
3 0

Answer:

The total amount paid by Jill  = $ (3 d)

Step-by-step explanation:

Here, the cost of 1 book = $ d

Now, the number of books purchased by Jill = 3

So, the total cost of 3 books  = 3 x ( Cost of 1 book)

                                                 = 3 x ($d)  = 3 d

So, if Jill purchased 3 books, the total amount paid by her = $ (3 d)

What are the solutions to the equation f(x)= g(x)?
PIT_PIT [208]

Answer:

2 solutions

Step-by-step explanation:

We are given the equations of f(x) and g(x).

To find f(x) = g(x), we just let those two equations equal each other

x^{2} -4x+5=x+1

Group all like terms,

x^{2} -3x+4=0

Factorise,

(x-4)(x+1)=0

x=4, x=-1

Therefore, there are two solutions

Hope this helped!!

HELP ME! In a complete sentence, describe the relationship between the three angles in the diagram below. Write and solve an equ
AlexFokin [52]

Answer:

  b = 17

  ∠QPS = 124°

  ∠SPT = 17°

  ∠TPR = 39°

Step-by-step explanation:

  • The sum of the three angles shown is a linear angle, with a measure of 180°.

This fact can be used to write an equation:

  (8b -12)° +b° +(2b+5)° = 180°

  11b -7 = 180

  11b = 187

  b = 17

  8b -12 = 8(17) -12 = 124

  2b +5 = 2(17) +5 = 39

The value of b is 17.

The angle measures are ...

  ∠QPS = 124°

  ∠SPT = 17°

  ∠TPR = 39°

The length f a rectangle is 3 ties its width, the perimeter of it is 24cm. what is the area of it?
andreyandreev [35.5K]

Answer: 27cm²

Step-by-step explanation:

lets take the width as x and length as 3x( since length is 3 times the width)…

Perimeter of the rectangle is 24 cm( 2*(l+b))= 2×(3x+x):24

2×4x=24

8x=24

X( width): 24/8=3cm

Length= 3x: 3*3=9cm

Area of the rectangle: ( l*w)= 9×3: 27cm²
