Zoe counts 5 times as many black kittens as white kittens for sale at the pet store. she counts a total of 25 kittens how many m

malfutka [58]

Let us say that:

a = black kittens

b = white kittens

We know that:

a = 5 b

a + b = 25

Therefore:

5 b + b = 25

6 b = 25

b = 4.17

But we cannot have a fraction value for the number of kittens, so round off:

b = 4

So a is:

a = 25 – 4 = 21

Hence Zoe counts additional 1 black kitten.

The length of a rectangle is 6m longer than its width. If the perimeter of the rectangle is 52m, find its area

sveticcg [70]

If length is x, then width is 6+x
Perimeter = 2*(x + 6+x) = 52 
2*6 + 2*2x = 52 
4x = 52 - 12 = 40 
x = 40/4 = 10 

Area = length*width = 10*(6+10) 
Area = 10*16 = 160 meter square

Please help!!!!!!!!!!

Delicious77 [7]

$f(x)=2x^2-4x+1$

Substitute the values of x to the equation of the function f:

$x=-1\to f(-1)=2(-1)^2-4(-1)+1=2(1)+4+1=7\\\\x=2\to f(2)=2(2^2)-4(2)+1=2(4)-8+1=1$

Therefore we have two points (-1, 7) and (2, 1).

We can calculate the slope of line l.

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

Substitute:

$m=\dfrac{1-7}{2-(-1)}=\dfrac{-6}{3}=-2$

<h3>Answer: A) -2.</h3>

(60)x = 1, what are the possible values of x? Explain your answer.

Gnesinka [82]

Answer:

$\frac{1}{60}$

Step-by-step explanation:

Problem:

The possible values of x in the equation (60)x = 1;

Solution:

Such a problem like this in which the highest power of the unknown is 1 will have just one solution.

60x = 1

To solve this, we take the multiplicative inverse of 60;

the multiplicative inverse of 60 = $\frac{1}{60}$

Use this inverse to multiply both sides of the expression;

$\frac{1}{60}$ $x$ 60x = 1 x $\frac{1}{60}$

x = $\frac{1}{60}$
