Answer:

63

Step-by-step explanation:

Set up the proportion

(6x+3)/17 = (8x - 1)/21                 Cross Multiply

21 * (6x + 3) = 17 (8x - 1)             Remove the brackets

126x + 63 = 136x - 17                 Subtract 126x from both sides

63 = 136x - 126x - 17                 Combine

63 = 10x - 17                              Add 17 to both sides

63 + 17 = 10x                             Combine the left

80        = 10 x                             Divide by 10

80/10 = x

x = 8

Now you want 8x - 1

8*8 - 1 = 63

If five slices of pizza costs 5.50 how much would two slices cost? ten slices? half a slice?
tensa zangetsu [6.8K]

Answer:

The first thing we must do for this case is to define variables.

We have then:

x: number of slices

y: total cost

We write the linear function that relates the variables.

We have then:

Then, we evaluate the number of slices to find the total cost.

-two slices cost:

We substitute x = 2 in the given equation:

Answer:

two slices = 2.2 $

-ten slices cost:

We substitute x = 10 in the given equation:

Answer:

ten slices = 11 $

-half a slice cost:

We substitute x = 1/2 in the given equation:

Answer:

half a slice = 0.55 $

Lesechka [4]

Answer:

29622 m^2

Step-by-step explanation:

SA = 2 ( lw+ wh+ lh)  where l = length  w = width  h = height

SA = 2 ( 81*75+ 75* 56+ 81*56)

     = 2 (6075+4200+4536)

      = 2(14811)

The function g(x) is a transformation of the quadratic parent function, fx):
77julia77 [94]

Answer: D

Step-by-step explanation:

The graph is narrower, so the coefficient of x^2 has an absolute value more than 1.

  • Eliminate B and C.

Also, because g(x) opens down, the coefficient of x^2 is negative.

  • Eliminate A.

This leaves D as the answer.

Pleaseeee helppppp meeee
abruzzese [7]

Answer:

y = 11x

Step-by-step explanation:

We have two points so we can find the slope

(1,11) and (2,22)

m = (y2-y1)/ (x2-x1)

   = (22-11)/(2-1)

   = 11/1

The slope is 11

We can use the point slope form to get an equation

y-y1 = m(x-x1)

y-11 = 11(x-1)

Distribute the 11

y-11=11x -11

Add 11 to each side

y-11+11 = 11x-11+11

y = 11x
