A bag has 30 tiles, numbered 1-30. Write the ratio even tiles to odd tiles in simplest form.

guapka [62]

Answer:

r=1

Step-by-step explanation:

<u>Ratio of Values </u>

A ratio compares two values by diving them. If the ratio is greater than one, then the value in the numerator is greater than the value in the denominator. The opposite relation gives ratios lower than 1. A ratio of 1 means both values are the same

We have a set of tiles numbered 1 to 30:

1,2,3,4,5,6...,29,30

Note that each odd-numbered tile is followed by an even-numbered tile. It means we have 15 odd tiles and 15 even tiles. The ratio is

$\displaystyle r=\frac{even}{odd}$

$\displaystyle r=\frac{15}{15}$

r=1

3p-2 greater than or equal to 4 or 7p>-28

Leona [35]

Answer:

$\large \boxed{\boxed{p>-4}}}$

Step-by-step explanation:

$3p-2\geq4\ or\ 7p>-28\\\\(1)\\3p-2\geq4\qquad\text{add 2 to both sides}\\3p-2+2\geq4+2\\3p\geq6\qquad\text{divide both sides by 3}\\\dfrac{3p}{3}\geq\dfrac{6}{3}\\\boxed{p\geq2}\\\\(2)\\7p>-28\qquad\text{divide both sides by 7}\\\dfrac{7p}{7}>-\dfrac{28}{7}\\\boxed{p>-4}\\\\\text{From (1) and (2) we have:}\\\\p\geq2\ or\ p>-4\Rightarrow \boxed{\boxed{p>-4}}$

Dolve the equation <br> 11q-6=3q+8q

Amanda [17]

Answer:

no solution

Step-by-step explanation:

Simplifying

11q + -6 = 3q + 8q

Reorder the terms:

-6 + 11q = 3q + 8q

Combine like terms: 3q + 8q = 11q

-6 + 11q = 11q

Add '-11q' to each side of the equation.

-6 + 11q + -11q = 11q + -11q

Combine like terms: 11q + -11q = 0

-6 + 0 = 11q + -11q

-6 = 11q + -11q

Combine like terms: 11q + -11q = 0

-6 = 0

Solving

-6 = 0

Couldn't find a variable to solve for.

This equation is invalid, the left and right sides are not equal, therefore there is no solution.
