Answer:

Well, I'm not sure what you mean but Ptolemy's Theorem gives a relationship between the side lengths and the diagonals of a cyclic quadrilateral; it is the equality case of Ptolemy's Inequality. Ptolemy's Theorem frequently shows up as an intermediate step in problems involving inscribed figures.

Michael rode his bike 2 2/3 miles on saturday. He rode another 1 5/6 miles on Sunday. How many miles did Michael ride his bike o

svlad2 [7]

To find the miles Michael rode, we can simply add up the miles he rode for both day:

$2 \frac{2}{3} + 1 \frac{5}{6} \\ = \frac{2 + 2 \times 3}{3} + \frac{5 + 6}{6} \\ = \frac{8 \times 2}{3 \times 2} + \frac{11}{6} \\ = \frac{16 + 11}{6} \\ = \frac{27}{6} \\ = 4 \frac{3}{6} \\ = 4 \frac{1}{2}$
Therefore the answer is 4 1/2 miles.

Hope it helps!

Emmanuel bought 40 lb of potting soil this week. This amount is 4 lb more than three times the amount of potting soil he bought

aivan3 [116]

(a)
The unknown information is the amount of potting soil Emmanuel bought last week.

(b)
40 lb of potting soil is 4 lb more than 3 times p (the amount of potting soil he bought last week).

The equation:
$40=3p+4$

(c)
$40=3p+4 \ \ \ |\hbox{subtract 4} \\
36=3p \ \ \ \ \ \ \ \ |\hbox{divide by 3} \\
p=12$

The solution to the equation is 12.

(d)
Last week Emmanuel bought 12 lb of potting soil.

Alonzo wrote the equation x = 2+4y-5. Which equation is equivalent?

elena-s [515]

Consider the equation $x = 2+4y-5$ , it can be expressed as $x = 4y-3$ .

Now, we have to write the equivalent equation.

Since, Equivalent equations are those equations which have exactly same solution. We can say that the two equations are equivalent if solution of one equation is the solution of other equation.

So, consider the equation $x = 4y -3$

Equivalent equation can be obtained by multiplying the given equation by any number say '2'.

Multiplying both sides of the given equation by '2'.

$x = 4y-3$

$2 \times x = 2 \times (4y-3)$

$2x = (2 \times 4y)-( 2 \times 3)$

$2x = 8y-6$ is the required equivalent equation.
