Answer:

The more accurate thing to do would be to work out the exact value. However, if in a rush, you should estimate the value with the prices rounded to the next whole number.

PLEASE HELP ASAP FOR LOTS OF POINTS AND BRAINLIEST

Answer:

x = 55

y = 60

Step-by-step explanation:

If a quadrilateral is inscribed in a circle, then its opposite angles are supplementary. So E and G are supplementary, and H and F are supplementary.

x + 15 + 2x = 180

3x + 15 = 180          combine like terms

3x = 165                  subtract 15 from both sides

x = 55                       divide both sides by 3

y + 3y - 60 = 180

4y - 60 = 180           combine like terms

4y = 240                  subtract 60 from both sides

y = 60                      divide both sides by 4

Write the equation of the graph shown below in factored form.
Ira Lisetskai [31]

Answer:

  y = (x +2)(x -1)(x -3)

Step-by-step explanation:

For each x-intercept (r) the corresponding factor is (x -r). For x-intercepts -2, 1, 3, the factors are ... (x+2), (x-1), (x-3). Then the equation is ...

  y = (x +2)(x -1)(x -3)

Can someone assist me with this?
Mnenie [13.5K]

Answer:

29: 7

Step-by-step explanation:

\frac{8}{3x - y}  =  \frac{5}{x + 3y}

<em>Cross</em><em> </em><em>multiply</em><em>:</em>

8(x + 3y) = 5(3x - y)

<em>Expand</em><em> </em><em>bracket</em><em>:</em>

8x + 24y = 15x - 5y

<em>Bring</em><em> </em><em>x</em><em> </em><em>terms</em><em> </em><em>to</em><em> </em><em>1</em><em> </em><em>side</em><em>,</em><em> </em><em>y</em><em> </em><em>terms</em><em> </em><em>to</em><em> </em><em>the</em><em> </em><em>other</em><em>:</em>

15x - 8x = 24y + 5y

<em>Simplify</em><em>:</em>

<em>7x = 29y</em>

<em>Divide</em><em> </em><em>by</em><em> </em><em>7</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>:</em>

x =  \frac{29}{7} y

<em>Divide</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>by</em><em> </em><em>y</em><em>:</em>

<em>\frac{x}{y}  =  \frac{29}{7}</em>

∴ The ratio of x to y is 29:7.
