Henry has twice as many fiction.

Mathematics

Lostsunrise [7]3 years ago

Let x be the number of non-fiction books. We deduce that the number of fiction books is 2x, since they are twice as much.

Since the difference between the two numbers is 17, we have

2x-x=17\iff x=17

So, Henry has 17 non-fictional and 34 fictional books, for a total of 51 books.

Please help me‼️‼️‼️‼️‼️‼️‼️‼️‼️
galina1969 [7]

Step-by-step explanation:

1 m = 3.280839895... ft

therefore,

1 m² = 10.76391042... ft²

35 m² = 35 × 10.76391042... ft² =

= 376.7368646... ft²

the area of the circle is

pi×r²

r = 50/2 = 25 ft

so, the area of the red circle is

pi×25² = pi×625 = 1,963.495408... ft²

we need to paint it twice, so the area to be painted is twice the area of the circle

2×pi×625 = 3,926.990817... ft²

we need a many cans as the cover area of a single can fits into the total area to be painted :

3,926.990817... / 376.7368646... = 10.42369671... cans

we need to round this up to full cans.

so, we need 11 cans of red paint to give that red pad 2 coats of paint.

Solve the rational equation x divided by 6 equals x squared divided by quantity x minus 1 end quantity, and check for extraneous
pychu [463]

Answer:

x = 0 and x = \textrm{negative one fifth}

Step-by-step explanation:

Given:

The rational equation to solve is given as:

\frac{x}{6}=\frac{x^2}{x-1}


We use the cross multiplication rule and multiply the numerators one side with the denominators of the other side. Therefore,

x\times (x-1)=6\times x^2\\x^2-x=6x^2\\\textrm{Bringing all variables to the right side, we get:}\\6x^2-x^2+x=0\\5x^2+x=0\\x(5x+1)=0\\x=0\ or\ 5x+1=0\\x=0\ or\ x=-\frac{1}{5}


Now, for x=0, the rational equation is equal to 0. So, x=0 is a solution.

Also, x=-\frac{1}{5} is also a solution as the equation's denominator is defined at that point.

So, no extraneous solution.
