Answer:

$\frac{1}{8}$

Step-by-step explanation:

To divide the 2 fractions

leave the first, change division to multiplication and turn the second upside down, that is

$\frac{2}{20}$ × $\frac{10}{8}$ ( cancel 2 and 8 by 2 and 10 and 20 by 10 )

= $\frac{1}{2}$ × $\frac{1}{4}$ ( multiply numerators and denominators )

= $\frac{1}{8}$

Answer: y = |x+3|-2

Step-by-step explanation:

The answer is the second one, y = |x+3|-2

It's similar to Parabola, |x+3|-2 is just like (x+3)^2-2, except about the graph. So (-3,-2)

Of the total number of spectators at a circus show, 1/4 are men. 2/5 of the remaining number of spectators are women. There are

ch4aika [34]

Answer: There are $198$ children at the circus show.

Step-by-step explanation:

Let be "x" the total number of spectators at the circus show and "c" the number of children at the circus show.

Knowing that $\frac{1}{4}$ of the spectators are men, we can find the remaining:

$x-\frac{1}{4}x=\frac{3}{4}x$

Since $\frac{2}{5}$ of the remaining number of spectaros are women and there are a total of 132 women, we can write the following equation:

$(\frac{2}{5})(\frac{3}{4}x)=132$

Solving for "x", we get:

$x=(132)(\frac{20}{6})\\\\x=440$

Therefore, we get that "c" is:

$c=440-\frac{1}{4}(440)-132\\\\c=198$

Select all expressions that are equivalent to 4x+2(2x-5)-(3-5x)

Arada [10]

For this case we have the following expression:

$4x + 2 (2x-5) - (3-5x)$

Applying distributive property to the terms within parentheses taking into account that:

$- * + = -\\- * - = +$

We have:

$4x + 4x-10-3 + 5x =$

We add similar terms taking into account that:

Equal signs are added and the same sign is placed.

$4x + 4x + 5x-10-3 =\\13x-13$

Thus, an equivalent expression is:

$13x-13$

Answer:

$13x-13$
